Abstract
Heavy metal-enriched fly ash (FA) deposits are recognized as hazardous contaminated sites on the earth, which pollute our ecosystems. Consequently, the present investigation was carried out to explore the phytoremediation potential of naturally growing medicinal plants in the FA dumpsite. This present study chose two native medicinal plants i.e., Bacopa monnieri and Acmella oleracea found to be naturally colonizing abundantly on FA dumpsite to assess heavy metal accumulation. FA sample of B. monnieri thriving sites found to have metal content in order Mn (216.6)> Cr (39.27)> Zn (20.8)> Ni (16.1)> Cu (15.03)> Co (6.7)> Pb (5.43) whereas for A. oleracea FA dumpsites, the order of metal availability was Mn (750.3)> B (54.5)>Cr (37.2)>Zn (31.33)> Cu (18.7)> Ni (16.93)> Co (7.7)>Pb (4.23). In B. monnieri, higher concentrations of Cr and Mn were observed in the shoot in comparison to the root, indicative of its potential as a hyperaccumulator plant. Conversely, in A. oleracea, greater amounts of Pb were detected in the shoot relative to the root. Hence, it is recommended that B. monnieri and A. oleracea grow on such heavy metal-enriched substrates should be avoided for medicinal purposes; however, these plants can be used for phytoremediation purposes.

Abstract
Fly ash application to the soil at lower doses with organic substrates has been advocated by researchers due to its beneficial soil ameliorative properties. But its xenobiotic effects in presence of vermicompost have not yet been studied fully. The hypothesis of the present study was to ascertain the ameliorative effects of fly ash and vermicompost amendment on the soil nematode and earthworm count and change in the soil carbon pool of the rice nursery. The native soil, fly ash, and vermicompost at 0%, 20%, 40%, 60%, 80%, and 100% combinations (by weight) in triplicate were investigated under a factorial complete randomized design. The fly ash affected the earthworm survivability to an extent that the earthworms could not survive in fly ash of concentration greater than 20%. On the contrary, the concentration of vermicompost positively influenced the earthworm and nematode count in the rice rhizosphere. The population of nematodes viz. Rhabditis terricola and Dorylaimids in the rhizosphere of rice nursery was positively linked with the vermicompost concentration, while fly ash had antagonistic effects. The absence of nematodes and earthworms at a higher concentration of fly ash could be linked to the xenobiotic effects of fly ash. However, on mild addition of fly ash and vermicompost (20% each) to the native soil, the carbon stock increased positively to the maximum extent due to the larger surface area of fly ash and its xenobiotic effects limiting respirational carbon loss.

Abstract
Aquatic algal communities demonstrated their appeal for diverse industrial applications due to their vast availability, ease of harvest, lower production costs, and ability to biosynthesize valuable molecules. Algal biomass is promising because it can multiply in water and on land. Integrated algal systems have a significant advantage in wastewater treatment due to their ability to use phosphorus and nitrogen, simultaneously accumulating heavy metals and toxic substances. Several species of microalgae have adapted to thrive in these harsh environmental circumstances. The potential of algal communities contributes to achieving the United Nations' sustainable development goals in improving aquaculture, combating climate change, reducing carbon dioxide (CO2) emissions, and providing biomass as a biofuel feedstock. Algal-based biomass processing technology facilitates the development of a circular bio-economy that is both commercially and ecologically viable. An integrated bio-refinery process featuring zero waste discharge could be a sustainable solution. In the current review, we will highlight wastewater management by algal species. In addition, designing and optimizing algal bioreactors for wastewater treatment have also been incorporated.

Abstract
Technogenic soil (technosol) developed from coal fly ash (FA) landfilling has been considered a critical environmental problem worldwide. Drought-tolerant plants often naturally grow on FA technosol. However, the impact of these natural revegetations on the recovery of multiple ecosystem functions (multifunctionality) remains largely unexplored and poorly understood. Here we assessed the response of multifunctionality, including nutrient cycling (i.e., carbon, nitrogen, and phosphorus), carbon storage, glomalin-related soil protein (GRSP), plant productivity, microbial biomass carbon (MBC), microbial processes (soil enzyme activities), and soil chemical properties (pH and electrical conductivity; EC) to FA technosol ten years' natural revegetation with different multipurpose species in Indo-Gangetic plain, and identified the key factors regulating ecosystem multifunctionality during reclamation. We evaluated four dominant revegetated species: Prosopis juliflora, Saccharum spontaneum, Ipomoea carnea, and Cynodon dactylon. We found that natural revegetation initiated the recovery of ecosystem multifunctionality on technosol, with greater recovery under higher biomass-producing species (P. juliflora and S. spontaneum) than lower biomass-producing ones (I. carnea and C. dactylon). The individual functions (11 of the total 16 variables) at higher functionality (70 % threshold) also exhibited this pattern among revegetated stands. Multivariate analyses revealed that most of the variables (except EC) significantly correlated with multifunctionality, indicating the capability of multifunctionality to consider the tradeoff between individual functions. We further performed structural equation modeling (SEM) to detect the effect of vegetation, pH, nutrients, and microbial activity (MBC and microbial processes) on ecosystem multifunctionality. Our SEM model predicted 98 % of the variation in multifunctionality and confirmed that the indirect effect of vegetation mediated by microbial activity is more important for multifunctionality than their direct effect. Collectively, our results demonstrate that FA technosol revegetation with high biomass-producing multipurpose species promotes ecosystem multifunctionality and emphasizes the significance of microbial activity in the recovery and maintenance of ecosystem attributes.

Abstract
Hyperaccumulators' ability to take up large quantities of harmful heavy metals from contaminated soils and store them in their foliage makes them promising organisms for bioremediation. Here we demonstrate that some ecotypes of the zinc hyperaccumulator Arabidopsis halleri are more suitable for bioremediation than others, because of their distinct influence on soil biota. In a field experiment, populations originating from metal-polluted and unpolluted soils were transplanted to a highly contaminated metalliferous site in Southern Poland. Effects of plant ecotypes on soil biota were assessed by measurements of feeding activity of soil fauna (bait-lamina test) and catabolic activity and functional diversity of soil bacteria underneath A. halleri plants (Biolog® ECO plates). Chemical soil properties, plant morphological parameters, and zinc concentration in shoots and roots were additionally evaluated. Higher soil fauna feeding activity and higher bacterial community functional diversity were found in soils affected by A. halleri plants originating from metallicolous compared to non-metallicolous ecotypes. Differences in community-level physiological profiles further evidenced changes in microbial communities in response to plant ecotype. These soil characteristics were positively correlated with plant size. No differences in zinc content in shoots and roots, zinc translocation ratio, and plant morphology were observed between metallicolous and non-metallicolous plants. Our results indicate strong associations between A. halleri ecotype and soil microbial community properties. In particular, the improvement of soil biological properties by metallicolous accessions should be further explored to optimize hyperaccumulator-based bioremediation technologies.

Abstract
Fly ash is an inevitable by-product from the coal-fired power plants in many developing countries including India that needs safe, timely and productive disposal. The addition of fly ash alters physicochemical properties of soil and hence could be used as a soil conditioner or modifier along with the appropriate level of vermicompost to support plant growth. Several studies have focalized sole use of fly ash and vermicompost in agricultural production systems lacking information on combined application effects. This work was carried out at Chiplima in the district of Sambalpur, Odisha, India, to ascertain the best suited combination of native soil, fly ash and vermicompost (from farmyard manure) for rice nursery based on the changing physicochemical properties and seedling growth. The experiment consisting of 21 treatment combinations of soil, fly ash and vermicompost at 0%, 20%, 40%, 60%, 80% and 100% by weight was laid out in a factorial complete randomized design with three replications. Fly ash and vermicompost at moderate concentrations significantly ameliorated the physical properties, viz., porosity, bulk and particle densities, water holding capacity, infiltration rate and the capillary rise of water in rice nursery soil that ultimately resulted in vigorous rice seedlings at 40 DAS through beneficial soil biota as well as better root and shoot development. The porosity, water holding capacity and infiltration rate significantly increased with the addition of vermicompost while fly ash addition substantially reduced them. Fly ash and vermicompost in moderate quantities smothered soil chemical properties like electrical conductivity and organic carbon that increased the availability of N, P, K, B, S and Zn. The pH did not differ significantly due to treatment effects owing to a marginal difference in pH of the substrates, whereas electrical conductivity increased significantly with only marginal addition of fly ash to vermicompost. Considering the economic feasibility and environmental impacts, 40% soil + 20% fly ash + 40% vermicompost may be recommend to the farmers for wet rice nursery raising and also for remediating the coal fly ash in agricultural production system.

Abstract
The soil samples of old Zawar mine sites were sandy texture, basic, electric conductivity range from 16 to 59 dSm-1 with a high content of heavy metals of Zn, Pb, Cd, and Fe, indicating poor soil-health. Two bacterial isolates Pseudomonas aeruginosa HMR1 and P. aeruginosa HMR16 (GenBank-accession-number KJ191700 and KU174205, respectively), differed in the Phylogenetic tree based on 16S-rDNA sequences. HMR1 isolate showed the high potential of Plant growth-promoting attributes like IAA, Phosphate-solubilization, Exopolysaccharide production, and Proline activities at high concentration of Zn augmented nutrient media after 24 h, followed by HMR1 + HMR16 and HMR16. Both isolates were survived at 100 ppm Zn (w/v) concentration, followed by Pb, Cd, and Fe. Linear RL value from Langmuir and Freundlich isotherms revealed that the suitable condition of Zn adsorption by HMR1 was at pH8 with 40°C. The value of r2 from pseudo-second-order kinetics and Transmission-Electron-Microscopic analysis confirmed Zn adsorption by HMR1.

Abstract
The current study focused on the pollution remediation of textile industry wastewater by using Chlorella pyrenoidosa in two different physical forms: free algal biomass and immobilized algal biomass. The hypothesis behind the present study was to analyze the pollution reduction efficiency of immobilized algal biomass and free algal biomass on comparative scale on the basis of the adsorption process which is directly proportional with the surface area of the adsorbate. So, in this context the immobilized form of algae could enhance the pollution reduction efficiency due to availability of more surface area. So, the textile industry wastewater was treated by both free algal biomass and immobilized algal biomass and the major wastewater contributors like nitrate, phosphate, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) were assessed before and after the treatment process. To conclude the optimum comparative results, the pH of wastewater was maintained constant, as it can capitalize or moderate the adsorption process (initial pH of was 8.2 ± 0.1, but it was maintained to 8). The contamination remediation was found to be effective with immobilized algal biomass (46.7% of nitrate, 59.4% of phosphate, 83.1% BOD and 83.0% of COD) than free algal biomass (43.2% of nitrate, 56.7% of phosphate, 71.4% of BOD and 78.0% COD).

Abstract
Plant species possess a huge potential in restoration of fly ash ecosystem. Litter deposition and its decomposition in the ash deposited sites are two important processes of the fly ash ecosystem. In order to identify the biological potential of a plant species to aid restoration of fly ash deposited sites, it is needed to assess leaf litter decomposition as well as nutrient release pattern. In the present investigation, we studied the leaf litter decomposition of the plant species (Leucaena leucocephala, Pithecellobium dolce and Prosopis juliflora) and mix plantation in the fly ash ecosystem. The litter bag experiment was conducted in the area of plantation on the fly ash deposited site during a period of 365 days. Percentage of C and N was higher in L. leucocephala > P. dolce >Mix Plantation > P. juliflora while C/N ratio was higher in P. juliflora >Mix Plantation > L. leucocephala > P. dolce. L. leucocephala and P. dolce showed relatively fast decomposition rates (k = 1.27, 1.17), respectively while mix plantation (k = 0.82) and P. juliflora (k = 0.73) exhibited relatively slower decomposition rates. Thus, we noted that the decomposition rate of L. leucocephala was greater than the other selected species. This shows that the species having faster decomposition rate and nutrient release could be a factual choice for rehabilitation of fly ash deposited sites.

Abstract
The present study focuses on the possibility of applying fly ash to agricultural fields for enhancing the production of agricultural crops. In this study, Pisum sativum L. was grown from germination stage to maturation stage in phytoremediated and non-phytoremediated or raw fly ash-amended soil. All the morphological (height, biomass, number of leaf, and leaf size) and physiological parameters like, protein content, chlorophyll content, nitrate reductase activity, and peroxidase activity were monitored to understand the effects of fly ash or its usefulness for using it as a fertilizer for facilitating micronutrients. Major finding of this study is that 40% (w/w) of non-phytoremediated fly ash amendment could be used for field application. Percentage increase of toxic metals in below ground organs was 6% for Cd, 6% for Cr, 5% for Cu, 15% for Mn, and 7% for Pb when compared with the control. In the non-phytoremediated fly ash-amended set, heavy metals and metalloids were present in the grains only at higher amendments T3 (60%) and T4 (80%). However, except Cd, all the metals were below the permissible limits suggested by the WHO. Phytoremediated fly ash could be used as a fertilizer up to 100% for the cultivation of pea plant as metals concentrations were found either below detection limit or below the WHO permissible limit.

Abstract
The present study aimed to elucidate the remediation potential of visibly dominant, naturally growing plants obtained from an early colonized fly ash dump near a coal-based thermal power station. The vegetation comprised of grasses like Saccharum spontaneum L., Cynodon dactylon (L.) Pers., herbs such as Tephrosia purpurea (L.) Pers., Sida rhombifolia L., Dysphania ambrosioides (L.) Mosyakin & Clemants, Chromolaena odorata (L.) King & H.E. Robins along with tree saplings Butea monosperma (Lam.) Taub. The growth of the vegetation improved the N and P content of the ash. Average metal concentrations (mg kg-1) in the ash samples and plants were in order Mn (345.1) > Zn (63.7) > Ni (29.3) > Cu (16.8) > Cr (9.9) > Pb (1.7) > Cd (0.41) and Cr (58.58) > Zn (52.74) > Mn (39.09) > Cu (10.71) > Ni (7.45) > Pb (5.52) > Cd (0.14), respectively. The plants showed fly ash dump phytostabilization potential and accumulated Cr (80.19-178.11 mg kg-1) above maximum allowable concentrations for plant tissues. Positive correlations were also obtained for metal concentration in plant roots versus fly ash. Saccharum spontaneum showed highest biomass and is the most efficient plant which can be used for the restoration of ash dumps.

Abstract
The present study entails the phytoremediation potential of different bamboo species on 5-year-old FA-dumped site near Koradi thermal power plant of Nagpur, Maharashtra, India. The selected FA-dumped site was treated with farmyard manure, press mud, and bio fertilizer followed by plantation of six promising species of bamboo namely Bambusa balcooa Roxb., Dendrocalamus stocksii (Munro.) M. Kumar, Remesh and Unnikrishnan, Bambusa bambos (L.) Voss, Bambusa wamin E.G. Camus, Bambusa vulgaris var. striata (Lodd. ex Lindl.) Gamble, and Bambusa vulgaris var. vittata Riviere and Riviere. The experimental results indicated that the organic input in the FA-dumped site nourished the soil by improving its physico-chemical, and biological characteristics. The results revealed the contamination of the site with different trace elements in varied quantity including Cr (89.29 mg kg-1), Zn (84.77 mg kg-1), Ni (28.84 mg kg-1), Cu (22.91 mg kg-1), Li (19.65 mg kg-1), Pb (13.47 mg kg-1), and Cd (2.35 mg kg-1). A drastic reduction in concentration of heavy metals in FA was observed after 1 year of bamboo plantation as compared to the initial condition. The results showed that bamboo species are good excluders of Ba, Co, Cr, Li, Ni, Mn, and Zn, whereas they are good accumulators of Cd, Pb, and Cu. The values of biochemical parameters, such as pH, total chlorophyll, ascorbic acid (AA), and relative water content of all the bamboo leaves ranged from 5.11-5.70, 1.56-6.33 mg g-1, 0.16-0.19 mg g-1, and 60.23-76.68%, respectively. It is thereby concluded that the bamboo plantation with biofertilizers and organic amendments may indicate adaptive response to environmental pollution on FA-dumped site.

Abstract
The presence of heavy metal in soil and water resources has serious impact on human health. The study was designed to examine the phytoremediation ability of plant species that are growing naturally on the Zn-contaminated site. For the study, six plant species and their rhizospheric soil as well as non-rhizospheric soil samples were collected from different parts of the industrial sites for chemical and biological characterization. Visual observations and highest importance value index (IVI) through biodiversity study revealed potential plants as effective ecological tools for the restoration of the contaminated site. Among the plants, almost all were the most efficient in accumulating Fe, Mn, Cu and Zn in its shoots and roots, while Cynodon dactylon, Chloris virgata and Desmostachya bipinnata were found to be stabilizing Cr, Pb and Cd (bioconcentration factor in root = 7.95, 6.28 and 1.98 as well as translocation factor = 0.48, 0.46 and 0.78), respectively. Thus, the results of this study showed that the naturally growing plant species have phytoremediation potential to remediate the electroplating wastewater-contaminated site. These plant species are successful phytoremediators with their efficient metal stabilizing and well-evolved tolerance to heavy metal toxicity.

Abstract
Soil contamination by heavy metals and metalloids is a serious problem which needs to be addressed. There are several methods for removal of contaminants, but they are costly, while the method of phytoremediation is eco-friendly and cost-effective. Pteridophytes have been found to remediate heavy metal-contaminated soil. Pteridophytes are non-flowering plant that reproduces by spores. Pteris vittata has been reported as the first fern plant to hyperaccumulate arsenic. The Pteris species belongs to the order Pteridales. Other ferns that are known phytoremediators are, for example, Nephrolepis cordifolia and Hypolepis muelleri (identified as phytostabilisers of Cu, Pb, Zn and Ni); similarly Pteris umbrosa and Pteris cretica accumulate arsenic in leaves. So, pteridophytes have a number of species that accumulate contaminants. Many of them have been identified, while various other are being explored. The present review article describes the phytoremediation potential of pteridophytes plants and suggests as a potential asset for phytoremediation programs.

Abstract
A field study was carried out on fly ash (FA) dumps of Panki Thermal Power Station to assess the phytoaccumulation of elements in various plant parts of edible fruit tree Ziziphus mauritiana. Of the twelve analyzed elements, the highest concentration was found for Fe followed by Mn > Se > Zn > Mo > Cu > Cr > Pb > Cd >Ni > As > Co in rhizospheric substrate of Z. mauritiana grown on FA dumps. Metal accumulation, bioconcentration factor, and translocation factor for each metal were calculated in various parts of the edible fruit tree. Significant variations of metal accumulations were observed among various plant parts. Accumulation of toxic elements was higher in roots, and it gradually declined toward the aerial parts of the plant corresponding to its distance from the ground. The concentration of some elements in fruit tree was found to be above prescribed limits in edible parts. Therefore, the present study suggested that additional care should be undertaken, if edible fruit trees are considered for phytoremediation or afforestation programs of FA dumps.

Abstract
The present study was focused on field research to examine the phytoremediation potential of naturally grown Eichhornia crassipes in fly ash (FA) pond. Field results indicate the efficiency of E. crassipes for remediation of heavy metals from FA pond. The bioconcentration factor trend was Cr (3.75) > Cu (2.62) > Cd (1.05), and Cu (1.35) in root and stem, respectively. The survival and abundance growth of E. crassipes in the circumstance of heavy metal enriched FA pond is another highlight of the present research that reveals its toxitolerant characteristics. Thus, this lesson on phytoremediation proved that E. crassipes is a potential accumulator of Cu, Cr, and Cd from FA ponds and is a promising species for FA pond's remediation globally.

Abstract
Proliferation of fly ash (FA) deposits and its toxicity have become a global concern, which contaminate the ecosystems of our Earth. In this regard, identification of potential plant species for FA deposits' restoration is the main concern. Keeping this view in mind, the present study was conducted to identify potential plant species naturally growing on FA deposits for the restoration purposes. Six intensive surveys were made during 2010-2014 to collect naturally growing plant species during different seasons from two FA deposits in Unchahar of Raebareli district, Uttar Pradesh, India. The plant species having potential for FA deposits' restoration were identified on the basis of their ecological importance, dominance at the study sites and socio-economic importance for rural livelihoods. Typha latifolia L., Cynodon dactylon (L.) Pers., Saccharum spontaneum L., Saccharum bengalense Retz. (syn. Saccharum munja), Prosopis juliflora (Sw.) DC., Ipomoea carnea Jacq. and Acacia nelotica L. are identified as potential plant species for FA deposits' restoration. Furthermore, the characteristics of naturally colonized species can be used for the phytorestoration during a revegetation plan of new FA deposits for multiple benefits.

Abstract
There are reports that the application of fly ash, compost and press mud or a combination thereof, improves plant growth, soil microbial communities etc. Also, fly ash in combination with farmyard manure or other organic amendments improves soil physico-chemical characteristics, rice yield and microbial processes in paddy fields. However, the knowledge about the impact of fly ash inputs alone or in combination with other organic amendments on soil methanotrophs number in paddy soils is almost lacking. We hypothesized that fly ash application at lower doses in paddy agriculture soil could be a potential amendment to elevate the paddy yields and methanotrophs number. Here we demonstrate the impact of fly ash and press mud inputs on number of methanotrophs, antioxidants, antioxidative enzymatic activities and paddy yields at agriculture farm. The impact of amendments was significant for methanotrophs number, heavy metal concentration, antioxidant contents, antioxidant enzymatic activities and paddy yields. A negative correlation was existed between higher doses of fly ash-treatments and methanotrophs number (R(2)=0.833). The content of antioxidants and enzymatic activities in leaves of higher doses fly ash-treated rice plants increased in response to stresses due to heavy metal toxicity, which was negatively correlated with rice grain yield (R(2)=0.944) and paddy straw yield (R(2)=0.934). A positive correlation was noted between heavy metals concentrations and different antioxidant and enzymatic activities across different fly ash treated plots.The data of this study indicate that heavy metal toxicity of fly ash may cause oxidative stress in the paddy crop and the antioxidants and related enzymes could play a defensive role against phytotoxic damages. We concluded that fly ash at lower doses with press mud seems to offer the potential amendments to improving soil methanotrophs population and paddy crop yields for the nutrient poor agriculture soils.

Abstract
Abundance of naturally growing Azolla caroliniana (water fern) on the surface of metal enriched fly ash (FA) pond reflects its toxitolerant characteristics. Results indicate the efficiency of A. caroliniana for phytoremediation of FA pond because of its higher bioconcentration factor. The metal concentration ranged from 175 to 538 and 86 to 753mgkg(-1) in roots and fronds, respectively. Bioconcentration factor (BCF) values of all metals in root and frond ranged from 1.7 to18.6 and 1.8 to 11.0, respectively, which were greater than one and indicates the metal accumulation potential of A. caroliniana. Translocation factor (TF) ranged from 0.37 to 1.4 for various heavy metals. The field result proved that A. caroliniana is a potential accumulator for the examined heavy metals and can be used for phytoremediation of FA pond.

Abstract
A hydroponics experiment was conducted to examine the phytofiltration of Cd by Limnocharis flava (L.) Buchenau grown in low-level Cd-contaminated water. For this, 45 d old seedlings of L .flava were transferred to a floating-support culture system containing nutrient solution spiked with four levels of Cd (0.5, 1, 2 and 4 mg l(-1)) and were separately harvested after 3, 7, 21 and 30 d. After 30 d harvesting, the percentage removal of Cd from the above four treatments reached up to 98, 96, 95 and 93%, respectively. Interestingly, all treatments had higher growth rate than control at 95% confidence level and plants still remained healthy at 4 mg l(-1) Cd exposure. The bioaccumulation study showed a linear relationship of Cd (R(2)=0.896-0.999) in all plant parts with the exposure time (3-30 d) and Cd concentrations in hydroponics system (0.5-4 mg l(-1)). Although, the root of L. flava had higher Cd concentration than leaf and peduncles, the total Cd concentrations in aerial plant parts were higher than the roots. The maximum bioconcentration factor (BCF) and translocation factor (TF) value of L. flava were calculated as 984.42 and 1.43, respectively. Estimated Cd accumulation capacity of L. flava per unit area (m(2)) was found to be in the range of 218. 35-1698.92 mg m(-2).The experimental results demonstrated that L. flava is a suitable candidate for the phytofiltartion (>93%) of Cd from low-level Cd-contaminated water.

Abstract
The present study was undertaken to examine the influence of the application of fly ash (FA) into garden soil for Cajanus cajan L. cultivation and on accumulation and translocation of hazardous metals from FA to edible part. Numerous studies have been reported on the growth and yield of agricultural crops under FA stress; however, there is a dearth of studies recommending the safe utilization of fly ash for crop production. Pot experiments were conducted on C. cajan L., a widely cultivating legume in India for its highly nutritious seeds. C. cajan L. were grown in garden soil and amended with varying concentrations of FA in a weight/weight ratio (0%, 25%, 50% and 100%; w/w). Incorporation of fly ash from 25% to 100% in garden soil increases the levels of pH, particle density, porosity and water holding capacity from 3.47% to 26.39%, 3.98% to 26.14%, 37.50% to 147.92% and 163.16% to 318.42%, respectively, than the control while bulk density decrease respectively from 8.94% to 48.89%. Pot experiment found that accumulation and translocation of heavy metals in tested plant depends on the concentration of FA. Addition of FA at lower concentration (25%) had shown positive results in most of the studied parameters of growth and yield (14.23% than control). The experimental results confirmed that lower concentration of FA (25%) is safe for C. cajan cultivation, which not only enhanced the yield of C. cajan L. significantly but also ensured the translocation of heavy metals to edible parts within the critical limits.

Abstract
Coal-based power generation is a principal source of electricity in India and many other countries. About 15-30% of the total amount of residue generated during coal combustion is fly ash (FA). FA is generally alkaline in nature and contains many toxic metals like Cr, Pb, Hg, As and Cd along with many essential elements like S, B, Ca, Na, Fe, Zn, Mn and P. Dumped FA contaminates the biosphere by mobilization of its fine particles and hazardous metals. Despite the negative environmental impact of FA, coal continues to be a major source of power production in India and therefore FA disposal is a major environmental issue. To overcome this problem, FA dumping sites have been started as a potential resource for biomass production of tree species. Phytoremediation is a strategy that uses plants to degrade, stabilize, and remove contaminants from soils, water and waste FA. Phytomanagement of FA is based on the plants' root systems, high biomass, woody nature, native nature, and resistance to pH, salinity, and toxic metals. Recently Indian researchers mostly from the National Botanical Research Institute have been working on phytoremediation and revegetation of FA dykes, inoculation of bacterial strains for reducing FA stress and biomass production from FA dykes. Many international researchers have worked on reclamation, revegetation and utilization of FA. FA utilization saves resources, mainly land (topsoil), water, coal, limestone and chemical fertilizer. Safe utilization of FA is a major concern around the world and regulatory bodies are enforcing stringent rules for the proper management of FA. This article summarizes various viable avenues in India for FA utilization and environmental management.

Abstract
Reactive oxygen species are a part of the normal physiology of the biological system but their subsequent defence undergoes alteration during diseased conditions. Administration of anaesthesia for surgery may also alter the formation of reactive oxygen species. The present work deals with the comparative status of oxidative stress (lipid peroxidation) and anti-oxidant defence markers (superoxide dismutase and catalase) in blood in 3 groups of 15 patients each receiving halothane, relaxant vecuronium and spinal form of anaesthesia with lignocaine 5% heavy. The results obtained depict that the formation of malonyl dialdehyde as well as decrease in superoxide dismutase and catalase activities was highest in spinal anaesthesia followed by halothane and then relaxant group. Therefore, it seems important to consider the pre-operative anti-oxidant status while administering anaesthesia to such patients in order to provide biologically safe anaesthesia.

Abstract
We have investigated the presence of total, free, protein-bound and peptide-bound hydroxyproline (Hyp) in the plasma of different mammals viz., camel, bovine, sheep, human, rabbit and rat. Total Hyp was significantly highest in human followed by rabbit, rat, bovine, sheep and camel (P<0.001). Free Hyp was significantly highest in human followed by rabbit, rat, camel, bovine and sheep (P<0.001). However, the protein-bound Hyp content was significantly highest in rat followed by bovine, human, camel, rabbit and sheep (P<0.001). Peptide-bound Hyp was significantly highest in human plasma followed by sheep and rabbit (P<0.001). No peptide-bound Hyp was detected in the plasma of camel, bovine or rat. In the human plasma, peptide-bound Hyp constituted 60% of the total plasma Hyp, followed by protein-bound Hyp, which was 35% of the total, Hyp and free Hyp, which was 15% of the total plasma Hyp. In the sheep plasma peptide-bound Hyp constituted about 50% of total Hyp followed by protein-bound (40% of the total Hyp) and free Hyp, which formed 10% of total Hyp. In the rabbit plasma protein-bound Hyp constituted 50% of the total Hyp fraction, followed by peptide-bound and free, which constituted about 30 and 20%, respectively, of the total Hyp fraction of the plasma. Peptide-bound Hyp formed 92, 84 and 82% of the total plasma Hyp in rat, camel and bovine, respectively. Free Hyp constituted about 8% of the total plasma Hyp in rat and 18% of total Hyp in bovine and camel, respectively. The causes of the significant variations in different collagen structure and composition with respect to the different species examined are not known, however, these variations may results from differences in turn-over rate of Hyp in those species.

Abstract
The NADH methemoglobin-reductase (EC 1.6.2.2) is mainly responsible for the maintenance of hemoglobin in its reduced and active state. The present study reveals the comparative status of this enzyme in normal Beagle dogs, rats, mice, mastomys and hamsters erythrocytes. The spectrophotometric and electrophoretic determinations showed that the above mentioned enzyme was deficient in the Beagle dog's erythrocytes. Furthermore, in vitro studies on the sensitivity of these rodents and Beagle dogs hemolysate towards oxidants, like primaquine and sodium nitrate, depicted a higher level of methemoglobin formation in the Beagle dogs hemolysate as compared to that of the rodent species. The deficiency of methemoglobin reductase in Beagle dogs erythrocytes could be responsible for their increased sensitivity towards oxidant induced methemoglobinemia.

Abstract
BACKGROUND Plasmodium yoelii nigeriensis (P. y. nigeriensis) produces lethal malaria infection in Swiss albino mice. Tumor necrosis factor (TNF) has been implicated in the pathogenesis of malaria by production of reactive oxygen species. Chloroquine is a traditionally used antimalarial and has been postulated to inhibit TNF secretion during malaria infection. OBJECTIVE The study the comparative effect of chloroquine and TNF treatment on hepatic oxidative stress and antioxidant defense indices in normal and P. y. nigeriensis-infected mice. MATERIALS AND METHODS The mice were divided into six groups, each consisting of four to six animals. They were normal mice, normal mice treated with chloroquine, normal mice treated with TNF-alpha, P. y. nigeriensis-infected mice, P. y. nigeriensis-infected mice treated with chloroquine and P. y. nigeriensis-infected mice treated with TNF-alpha. RESULTS Chloroquine treatment of the normal mice caused no significant alterations in hepatic oxidative stress and antioxidant defense indices while TNF treatment of normal mice caused a significant decrease in hepatic superoxide dismutase. Chloroquine treatment of P. y. nigeriensis-infected mice caused a decrease in blood parasitemia which was accompanied by restoration of altered indices to near normal levels. However, TNF treatment of P. y. nigeriensis-infected mice had no effect on blood parasitemia but caused a significant increase of hepatic xanthine oxidase and lipid peroxidation and a decrease in the activity of hepatic superoxide dismutase. CONCLUSION Exogenous TNF acts synergistically with P. y. nigeriensis infection to generate oxidative stress in the host and also causes an impairment of the antioxidant defense enzyme SOD, while chloroquine treatment reduces the severity of malaria infection by decreasing the blood parasitemia and also perhaps by inhibiting the TNF release.

Abstract
The methemoglobin reductase system plays a vital role in maintaining the equilibrium between hemoglobin and methemoglobin in blood. Exposure of red blood cells to oxidative stress (pathological/physiological) may cause impairment to this equilibrium. We studied the status of erythrocytic methemoglobin and the related reductase system during Plasmodium yoelii nigeriensis infection in mice and P. berghei infection in mastomys. Malaria infection was induced by intraperitoneal inoculation with 10(6) infected erythrocytes. The present investigation revealed a significant decrease in the activity of methemoglobin reductase, with a concomitant rise in methemoglobin content during P. yoelii nigeriensis infection in mice erythrocytes. This was accompanied with a significant increase in reduced glutathione and ascorbate levels. The activity of lactate dehydrogenase, glucose 6-phosphate dehydrogenase and glutathione reductase increased with a progressive rise in parasitemia. However, no methemoglobin or associated reductase activity was detected in normal and P. berghei-infected mastomys. P. berghei infection in mastomys resulted in an increase in the level of reduced glutathione and ascorbate in erythrocytes, and also in the activity of lactate dehydrogenase, glucose 6-phosphate dehydrogenase and glutathione reductase. These results suggest that antioxidants/antioxidant enzymes may prevent or reduce the formation of methemoglobin in the host and thereby protect the host from methemoglobinemia.

Abstract
BACKGROUND The methemoglobin reductase system plays a vital role in maintaining the equilibrium between hemoglobin (Hb) and methemoglobin (MetHb) in blood. Exposure of red blood cells to an oxidative stress (pathological/physiological) may cause impairment in this equilibrium. OBJECTIVE The status of MetHb and the related reductase system was studied during Plasmodium yoelii nigeriensis (P. y. nigeriensis) infection and beta-arteether treatment in mice. METHODS Mice were divided into four groups. Normal group, normal mice treated with beta-arteether, P. y. nigeriensis infected mice and P. y. nigeriensis infected mice treated with beta-arteether. RESULTS The present investigation revealed a marked decrease in the activity of MetHb reductase, with concomitant rise in MetHb levels during P. y. nigeriensis infection in mice erythrocytes (P < 0.001) as compared to normal mice. However, the activities of the associated enzymes viz., lactate dehydrogenase, glucose 6-phosphate dehydrogenase and glutathione reductase were found to be increased with progressive rise in parasitemia. beta-Arteether treatment (12.5 mg/kg body weight) of infected mice (parasitemia 20-25%) from day 5 of post infection resulted in complete clearance of parasitemia on day 7 of post infection, which was accompanied by restoration of all the altered above mentioned indices to near normal levels as compared to infected mice (P < 0.001). CONCLUSION These results suggest that there is a marked impairment of methemoglobin and methemoglobin reductase system during P. y. nigeriensis infection in mice. beta-Arteether treatment of infected mice resulted in complete clearance of parasitemia which also caused the restoration of methemoglobin and methemoglobin reductase system to near normal levels.

Abstract
BACKGROUND Plasmodium yoelii nigeriensis (P. y. nigeriensis) produces lethal malaria infection in Swiss albino mice. Reactive oxygen species (ROS) are important mediators of tissue injury during malaria infection. OBJECTIVE To study the status of hepatic oxidative stress and antioxidant defense indices during Plasmodium yoelii nigeriensis (P. y. nigeriensis) infection and poly ICLC treatment of normal and P. y. nigeriensis infected Swiss albino mice. METHODS Mice were divided into four groups viz., 1. Normal mice, 2. Normal mice treated with poly ICLC (5 mg/kg body weight, i.p.), 3. P. y. nigeriensis infected mice and 4. P. y. nigeriensis infected mice treated with poly ICLC (5 mg/kg body weight, i.p.). RESULTS P. y. nigeriensis infection caused a significant increase in hepatic oxidative stress indices viz., xanthine oxidase and lipid peroxidation. This was accompanied by a significant increase in antioxidant defense indices viz., reduced glutathione (GSH), glutathione reductase while superoxide dismutase and catalase showed a significant decrease with respect to normal mice. Poly ICLC treatment of P. y. nigeriensis infected mice did not cure blood parasitemia. However, poly ICLC treatment of normal and P. y. nigeriensis resulted in an increased generation of hepatic oxidative stress and an associated increase in the antioxidant defense indices. CONCLUSION poly ICLC therapy alone is not sufficient to treat the malaria infection caused by multiple drug resistant strain of P. y. nigeriensis. Therefore there is a need to develop newer antimalarias which can act alone or in combination with traditional antimalarials to be effective against drug resistant malarial parasite.

Abstract
BACKGROUND Plasmodium yoelii nigeriensis (P. y. nigeriensis) produces lethal malaria infection in Swiss albino mice. Reactive oxygen species (ROS) such as superoxide anion, hydrogen peroxide along with endogenously produced tumor necrosis factor (TNF) have been implicated in the pathogenesis of malaria. OBJECTIVE Study the effect of TNF on hepatic oxidative stress and antioxidant defense indices in normal and P. y. nigeriensis infected mice. METHODS Mice were divided into four groups. Normal group, TNF treated group, P. y. nigeriensis infected group, and P. y. nigeriensis infected mice treated with TNF group (250 microg/kg body weight, i.p.). RESULTS TNF treatment of normal mice caused a highly significant decrease in hepatic superoxide dismutase (SOD) while changes in other oxidative stress and antioxidant defense indices were nonsignificant. On the other hand, TNF treatment of P. y. nigeriensis infected mice caused a highly significant increase in hepatic xanthine oxidase, lipid peroxidation and a significant decrease in hepatic SOD with respect to infected mice. CONCLUSION These results suggest that exogenous TNF acts synergistically with P. y. nigeriensis infection to generate oxidative stress in the host and also causes an impairment of antioxidant defense enzyme such as superoxide dismutase.

Abstract
1-(3'-Diethylaminopropyl)-3-(substituted phenylmethylene)pyrrolidines were synthesized and evaluated for CQ-resistant reversal activity. In general the compounds of the series elicit better biological response than their phenylmethyl analogues. The most active compound 4b has been evaluated in vivo in detail, and the results are presented. The possible mode of action of the compounds of this series is by inhibition of the enzyme heme oxygenase, thereby increasing the levels of heme and hemozoin, which are lethal to the parasite.

Abstract
Hepatic mitochondrial cytochrome P-450 and b(5) activities were significantly depressed, whereas heme and hemozoin were increased during Plasmodium yoelii infection. Type II, aniline-HCl binding efficacy and polyacrylamide gel electrophoretic profile also depicted impairment of cytochrome P-450 during infection. However, the above alterations were more pronounced in the infected hepatic mitochondria, compared to microsomes. Oral treatment of pyrimethamine (10 mg/kg body weightx4 days) to P. yoelii-infected mice brought the altered levels of mitochondrial and microsomal cytochrome P-450 and b(5) to almost normal, whereas heme and hemozoin levels remained unchanged.

Abstract
Methemoglobin, a toxic ferric form of hemoglobin, is continuously formed in normal erythrocytes, but during abnormal situations in situ, the level is enhanced. 8-Amino-quinolines and related compounds are causative agents for methemoglobin formation. Employing oxyhemoglobin, methemoglobin toxicity was about six times higher with primaquine compared to CDRI Compound 80/53 at 10(-9) M concentration. Methemoglobin reductase activity was also completely inhibited by primaquine, whereas 24% inhibition was noted in the case of 80/53 at the same concentrations. Mastomys, a rodent animal model, was found to be equally good for comparative evaluation of methemoglobin toxicity. Further, with the use of primaquine transdermal tape on the Mastomys model, a rise in methemoglobin occurred with increase in time. In conclusion, the study presents simple, economical, less time-consuming methods for the evaluation of methemoglobin toxicity, in vitro and in vivo, without employing the conventional Beagle dog model.

Abstract
Reactive Oxygen species play an important role in pathology during malaria infection. The status of hepatic oxidative stress and antioxidant defence indices was studied during Plasmodium yoelii nigeriensis (P. y. nigeriensis) infection in mice and arteether treatment of P. y. nigeriensis infected mice. P. y. nigeriensis infection caused a significant increase in hepatic xanthine oxidase, rate of lipid peroxidation, reduced glutathione (GSH) and glutathione reductase with progressive rise in parasitemia. This was accompanied by a significant decrease in hepatic superoxide dismutase (SOD) and catalase with increase in parasitemia. Arteether treatment (10 mg/kg body weight of mice) of infected mice from day 2 of post infection resulted in complete clearance of parasitemia on day 4 of post infection which was accompanied by restoration of all the oxidative stress and antioxidant defence indices to normal levels.

Abstract
Reactive oxygen species are important mediators of tissue injury during malaria infection. The status of hepatic oxidative stress and antioxidant defence indices were studied during Plasmodium yoelii nigeriensis (P. y. nigeriensis) infection and chloroquine/ polyinosinic-polycytidylic acid stabilized with polylysine and carboxymethylcellulose (poly ICLC) treatment of infected mice. P. y. nigeriensis infection resulted in a significant increase in oxidative stress indices viz., xanthine oxidase and rate of lipid peroxidation (LPO). This was accompanied by a highly significant increase in antioxidant defence indices viz., reduced glutathione (GSH) and glutathione reductase while superoxide dismutase (SOD) and catalase showed a highly significant decrease with respect to normal mice. Chloroquine treatment of infected mice caused a decrease in parasitaemia which was associated with restoration of indices altered during infection towards normalization. Poly ICLC treatment of infected mice caused no change in blood parasitaemia but resulted in a significant increase in GSH, glutathione reductase, SOD and catalase with respect to infected mice. Combination therapy of chloroquine and poly ICLC resulted in clearance of parasitaemia and restoration of all oxidative stress and antioxidant defence indices to normal levels.

Abstract
Glutathione-S-transferase (GST) activity has been detected in rodent (Plasmodium berghei, P. yoelii), simian (P. knowlesi) and human (P. falciparum) malarial parasites, and in different intraerythrocytic stages of P. knowlesi (schizont > ring > trophozoite). In chloroquine-resistant strains of rodent and human malarial parasites GST activity significantly increases compared to sensitive strains. Further, the increase in enzyme activity is directly related to drug pressure of resistant P. berghei. Complete inhibition of chloroquine-sensitive and resistant P. berghei glutathione-S-transferase activities was observed at 2.5 and 5. micrometer concentration of hemin, respectively. An inverse relationship was found between the heme level and enzyme activity of chloroquine-resistant and sensitive P. berghei. Chloroquine, artemisinin, and primaquine noticeably inhibited GST activity in P. knowlesi.

Abstract
Intraerythrocytic stages of cell-free Plasmodium knowlesi possess significant activities of heme biosynthetic enzymes, viz. delta-aminolevulinic acid synthase (delta-ALAS), delta-aminolevulinic acid dehydrase (delta-ALAD), ferrochelatase (FC), and tryptophan pyrrolase (enzyme representing free heme pool). delta-Aminolevulinic acid synthase and FC showed higher activities in schizont than in ring trophozoite stage. Uninfected monkey erythrocytes did not possess the above-mentioned enzyme activities; on the contrary, leucocytes showed detectable enzyme activities. delta-Aminolevulinic acid synthase was not appreciably inhibited by different antimalarials. Succinyl acetone and hemin exhibited a concentration-dependent inhibition of delta-ALAD and delta-ALAS, respectively.

Abstract
The pathophysiological impact of infections with chloroquine-susceptible (CQS) and chloroquine-resistant (CQR) strains of Plasmodium berghei in Mastomys natalensis was studied with respect to changes in polyamine profiles in various tissues. Both CQS and CQR infections produced similar changes in polyamine profiles of various tissues. Maximum increase was recorded in spleen followed by liver and lungs. Renal, cardiac and cerebral tissues did not register significant changes. An increase in spermidine level was more prominent as compared to putrescine and spermine, leading to an overall increase in spermidine/spermine ratio. This ratio is an important index of cellular proliferation. Liver did not show considerable change in the activities of ornithine decarboxylase and S-adenosyl methionine decarboxylase, the regulatory enzymes of the polyamine biosynthetic pathway. Spleen however, registered marked induction of both the enzymes which was more prominent in the CQS infection than CQR. Normal erythrocytes contained traces of polyamine while the erythrocytes loaded with P. berghei parasites exhibited appreciably higher polyamine levels. Spermidine was detected in about five-fold higher concentrations than putrescine and spermine which were detected in equimolar levels. Again, CQS as well as CQR P. berghei, exhibited qualitatively and quantitatively similar polyamine profiles thus ruling out a role of polyamines in CQ-resistance in malaria.

Abstract
Plasmodium yoelii infected cerebral microvessels of mice had an enhanced time-dependent, temperature-sensitive, and saturable uptake of [14C]-amino acid. viz. leucine, valine and glycine. Metabolic inhibitors caused a noticeable inhibition of amino acid uptake in normal microvessels as compared to infected cerebral microvessels indicating that the uptake of [14C]-L-leucine, [14C]-L-valine and [14C]-glycine is an energy dependent process.

Abstract
Plasmodium yoelii infection alters the hepatic levels of key enzymes of urea cycle, viz.carbamoyl phosphates synthetase (EC 6.3.4.16) and ornithine transcarbamoylase (EC 2.1.3.3) and urea levels in mice. The urea level was found elevated in liver, brain and plasma during P. yoelii infection. However, carbamoyl phosphate synthetase and ornithine transcarbamoylase were noticeably decreased during P. yoelii infection. Pyrimethamine treatment (10 mg/kg body weight for 4 days) brought back the altered parameters to normal a week after cessation of drug treatment.

Abstract
Plasmodium yoelii infection resulted in depression of hepatic mitochondrial and microsomal mixed-function oxidase system indices, e.g. cytochrome P-450, cytochrome b5 and phase II detoxification enzyme glutathione-S-transferase, while heam and haemozoin registered a marked increase in Swiss albino mice. Phenobarbitone (inducer) treatment showed induced levels of hepatic mitochondrial and microsomal cytochrome P-450 and glutathione-S-transferase in normal as well as in infected mice. The induced cytochrome P-450 and glutathione-S-transferase activities were similar in normal and infected mice. The findings were further supported by the isoenzymic profile and drug-binding properties of the terminal monoxygenase, cytochrome P-450.

Abstract
N-acetyl penicillamine (NAP), a derivative of penicillamine and copper chelator has been employed as a potential protector of host stress organ injury during Plasmodium berghei infection in mice. Intramuscular injection of NAP (60 mg kg-1 body wt for 10 days) to P. berghei mice was able to restrict the hepato- and splenomegaly. The mortality rate of infected mice was decreased by 50% by NAP. The decreased protein and lipid peroxidation and increased copper contents during P. berghei were almost normalized after NAP treatment. The increased levels of erythrocytic superoxide anion and lipid peroxides due to infection were almost normalized after NAP treatment.

Abstract
Ammonia, lactate, glutamate and pyruvate levels in blood, liver, brain, spleen and kidney were determined during Plasmodium yoelii infection and pyrimethamine treatment in mice. Ammonia and lactate levels showed significant increase with rise in parasitaemia except in spleen where decrease in the lactate levels was observed. The glutamate level displayed a marked decrease in blood, liver and splenic tissues, whereas, significant increase in glutamate level in kidney was observed, although its level in cerebral tissue remained unaltered. The pyruvate level in blood and liver showed a noticeable decrease but brain, spleen and kidney registered an elevation of the same due to the parasitic infection. Pyrimethamine (oral) treatment (10 mg/kg body weight) to infected mice (5-10%) for four days brought back the altered levels of the above cellular constituents in different tissues to normal, a week after cessation of drug treatment.

Abstract
Promastigotes of Leishmania donovani (Dd-8 strain) showed presence of important key enzymes of heme synthesizing (delta-aminolevulinic acid synthase and ferrochelatase) and degrading (heme oxygenase and biliverdin reductase) systems, classical leishmanicidal drugs viz allopurinol, amphotericin B, pentamidine and CDRI compound 93/202 inhibited the heme oxygenase activity of the parasite, whereas, delta-aminolevulinic acid synthase activity practically remained unaffected. The Km, Vmax and pH values of heme oxygenase of promastigotes were found to be 1666 microM hemin, 625 nmol of bilirubin formed h-1 mg protein-1 and 7.5 respectively. The findings suggest the presence and importance of heme metabolism in the de novo synthesis of different hemoproteins of the Leishmania parasite as well as the detoxification and its defence against biological insults.
