Abstract
The microplastisphere is a dense consortium of metabolically active microorganisms that develops on the surface of microplastics. Since the discovery that it harbors antibiotic resistance genes (ARGs), there has been a quest to decipher the relationship between ARG occurrences and selective enrichment with plastic types, which is important to understand their fate in diverse environmental settings. Nonetheless, it remains a neglected topic, and this developing field of microplastics research could benefit from a comprehensive review to acquire a deeper understanding of the most recent advances and drive scientific progress. Accordingly, the goal of this review is to critically discuss and provide an in-depth assessment of the evidence of ARGs' global nature in microplastispheres, as well as explore factors that influence them directly and indirectly, highlighting important concerns and knowledge gaps throughout the article. By comprehensively covering them, we underscore the potential environmental implications associated with microplastisphere ARGs. From our analysis, it emerged that microplastisphere ARGs are likely to be impacted not only by differences in microplastic types and characteristics but also by how their environments are shaped by other agents such as physiochemical properties, socioeconomic factors, and contaminants coexistence, influencing ARG subtype, incidence, abundance, and selective enrichment. The intricate relationship of microplastisphere ARGs to environmental conditions and plastic types calls for multilevel investigations to clearly assess the environmental fate of microplastics. We anticipate that this review could assist researchers in strengthening their foundation and identifying efforts to advance knowledge in this research field.

Abstract
Excess fluoride (F-) in groundwater can be hazardous to human health of local residents who rely upon it. Beside natural sources, anthropogenic input may be an additional source to be considered. Twenty surface water and 396 groundwater samples were collected from the Nansi Lake Basin, with hydrogeochemical and isotope techniques employed to clarify the spatial variability, source, and the natural and anthropogenic factors regulating the occurrence of high F- groundwater. The factors responsible for elevated F- levels in surface water and deep confined aquifers are discussed based on their hydraulic relationship. Also a conceptual model of F- enrichment with different aquifer systems is put forward based on the geomorphic units of the basin. The results show that F- concentration is between 0.1 and 6.9 mg/L in the west of Lake, while ranged from 0.03 to 1.74 mg/L in the east of Lake. The hydrogeological setting and lithology are the primary factor determining the provenance of high-fluoride groundwater in the basin. Fluoride mainly originated from the dissolution of fluorine-bearing minerals, and is affected by the alkaline groundwater environment, cation exchange, adsorption, and evaporation. The landforms on the east side of Nansi Lake are low hills and piedmont sedimentary plains, where the aquifers consist of karst fissure water and overlying porewater. High F- groundwater is not observed in this area due to its rapid flow and Ca2+-enriched hydrochemical characteristics. The anthropogenic input (such as fertilizer application on farms and illegal industrial pollutant discharge), contribute F- to groundwater in varying degrees, especially in the shallow aquifers east of the lake and in some parts west of the lake. This work is a clear example of how natural processes together with human activities can affect the chemical quality of groundwater, which is essential to safeguard the sustainable management of water resources in semi-arid areas.

Abstract
Multisite phosphorylation of proteins regulates various cellular life activities, however, the capture of low abundance multi-phosphopeptides from biosamples and identification of phosphorylation sites are largely limited due to the limited enrichment materials and their unclear interactions with multi-phosphopeptides. Here we propose using two cheap raw materials (CaCl2·2H2O and Na2HPO4·12H2O) in 10 min at room temperature to synthesize the structurally simple Nanometric Calcium Phosphate (CaP) to resolve this challenge. The current results showed that the "simple" CaP has good selection specificity, high sensitivity and stability for multi-phosphopeptides enrichment and the identification of phosphorylation sites, which facilitate the popularization and application of phosphoproteomics research. Further, the interaction of CaP and multi-phosphopeptides were qualitatively characterized at the molecular/atomic level and the high affinity between them was quantified by the isothermal titration microcalorimeter based on the laws of thermodynamics. The results indicated that the interaction was a spontaneous (ΔG < 0) exothermic reaction with enthalpy reduction (ΔH < 0) and driven mainly by hydrogen bond and electrostatic interaction process.

Abstract
Soils developed in karst regions have naturally high background values of molybdenum (Mo) due to geological factors. However, the enrichment mechanism of Mo in these soils are not fully understood, making it challenging to assess their ecological risk and utilize Mo-rich land resources. To shed light on this issue, this study collected and analyzed data from the 1:50,000 geochemical survey in Guangxi, including 536,503 sets of soil data and 3043 sets of rock data, as well as 40 sets of carbonate rock-soil from typical karst regions. The results showed that soil Mo enrichment is highly correlated with the distribution of carbonate rocks in karst regions. The carbonate rocks in these regions contain Mo ranging from 0.03 to 1.06 mg·kg-1 (with a mean of 0.22 mg·kg-1). In comparison, the soil Mo derived from carbonate rocks can reach up to 6.00 mg·kg-1 (with a mean of 2.75 mg·kg-1), representing an average enrichment of soil Mo that is 24 times higher compared to the carbonate parent rock. The enrichment of soil Mo in karst regions is primarily controlled by secondary enrichment during the weathering process of carbonate. During the insoluble residue accumulation process, the dissolution of carbonate leads to a dramatic reduction in bedrock volume, and the adsorption of clay minerals and Fe minerals in insoluble residues plays an essential role in Mo enrichment during these stages. During the soil-forming stage of the insoluble residue, most Mo leaches into the water body due to the mineral transformation of insoluble residue. Consequently, as Fe-Mn nodules in soils become more enriched with increasing weathering intensity, some Mo is absorbed and passivated by iron and manganese oxides (hydroxides). Accordingly, the contribution of Fe-Mn nodules and the degree of leaching were closely related to the enrichment of soil Mo in karst regions. This study provides insights into the enrichment mechanisms of Mo in soils developed in karst regions, which will help to evaluate their ecological risk in these environments.

Abstract
Uranium (U) geochemistry and its isotopic compositions of reservoir sediments in U mine area were poorly understood. Herein, U and Th isotopic compositions were employed to investigate source apportionment and geochemical behavior of U in 41 reservoir sediments from a U mining area, Guangdong, China. The remarkably high contents of both total U (207.3-1117.7 mg/kg) and acid-leachable U (90.3-638.5 mg/kg) in the sediments exhibit a severe U contamination and mobilization-release risk. The U/Th activity ratios (ARs) indicate that all sediments have been contaminated apparently by U as a result of discharge of U containing wastewater, especially uranium mill tailings (UMT) leachate, while the variations of U/Th ARs are dominated by U geochemical behaviors (mainly redox process and adsorption). The U isotopic compositions (δ238U) showed a large variance through the sediment profile, varying from - 0.62 to - 0.04‰. The relation between δ238U and acid-leachable U fraction demonstrates that the U isotopic fractionation in sediments can be controlled by bedrock weathering (natural activity), UMT leachate (anthropogenic activity) and subsequent biogeochemical processes. The findings suggest that U-Th isotopes are a powerful tool to better understand U geochemical processes and enrichment mechanism in sediments that were affected by combined sources and driving forces.

Abstract
The lack of information on the origin and behavior of iodine in deep groundwater restricts the development and use of groundwater resources. To address this issue, the Cangzhou region in the eastern North China Plain (NCP) was selected for a case study. In total, 296 deep groundwater samples were collected, their iodine concentrations were determined, and the distribution characteristics of iodine concentrations were analyzed. Iodine concentrations ranged from < 0.002 to 1.22 mg/L, with a mean of 0.19 mg/L; 42% of the samples had high iodine concentrations. The levels were higher in the east than in the west, and most of the samples with high iodine concentrations were obtained from sites east of the boundary between the Cangxian uplift and the Huanghua depression. The weathering and dissolution of iodine-bearing minerals and the leaching of marine sediments can facilitate iodine enrichment. In the Cangxian uplift, iodine was mainly a result of the conversion of organic iodine, while in the Huanghua depression, iodine enrichment was a factor of the conversion of IO3-. Overall, the main factors for the enrichment of iodine are the sedimentary environmental and the hydrodynamic conditions. Our results provide a theoretical basis to understand the occurrence of high iodine concentrations in deep groundwater.

Abstract
Microplastics (MPs) are found to be ubiquitous and serve as vectors for other contaminants, and the inevitable aging process changes MP properties and fates. However, whether the MPs in aging process affects the fates of antibiotic resistance gene (ARGs) in aquatic environments is poorly understood. Herein, the physicochemical property alteration of MPs being aged in landfill leachate, an important reservoir of MPs and ARGs, was investigated, and microbial community evolution and ARGs occurrence of MP surface during the aging process were analyzed. Aging process remarkably altered surface properties, including increasing specific surface areas, causing the formation of oxygen-containing groups, and changing surface morphology, which further increased the probability of microbial colonization. The bacterial assemblage on MPs showed higher biofilm-forming and pathogenic potential compared to leachate. ARGs quantification results suggested that MPs exhibited selective enrichment for ARGs in a ratio of 5.7-103 folds, and the aging process enhanced the enrichment potential. Further co-occurrence networks suggested that the existence of non-random, closer and more stable ARGs-bacterial taxa relations on MP surface affected the ARG transmission. The study of ARG partitioning on MPs indicated that extracellular DNA was a nonnegligible reservoir of ARGs attached on MP surface, and that biofilm bacterial community influenced ARGs partitioning pattern during the aging process. This study confirmed that the aging process could enhance the potential of MPs as vectors for ARGs, which would promote the holistic understanding of MP behavior and risk in natural environments.

Abstract
Antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in fertilizers pose risks to human health and their variation in soil after fertilization has been reported. However, some important questions, such as the origin of ARG and ARB observed in soil following fertilization, which are present in soil regardless of fertilizer type (i.e., core (shared) ARGs and ARB), and the contribution of various ARG subtypes to the soil antibiotic resistome, need to be addressed. In this study, the effects of a long-term (9-year) application of organic (manure) and inorganic (chemistry) fertilizers on ARGs in greenhouse soils growing vegetables were investigated using metagenomic sequencing. The results showed that both organic and inorganic fertilizers application increased the diversity and abundance of soil ARGs. The dominant ARG types in organic fertilizer (OF) were different from that in organic fertilizer treated soil (SO), inorganic fertilizer treated soil (SI) and no fertilizer control plots (SC). The difference of core ARGs abundance reflected the variation of ARG profiles among SC, SI and SO. The OF is likely a source of the elevated ARG subtypes in soil and almost all the soil core ARG subtypes can be detected in organic fertilizer. Fifteen ARG types were enriched in the soil with OF, and some ARG subtypes such as sul1, sul2, tetX and tetL might derived from OF while others including as vanR, tcmA, rosB, and mexF might be from indigenous microbes in soil. The nutrition factors were found to influence the ARG profiles in fertilized soil. In summary, this study revealed the possible reason for the soil total ARG numbers and their relative abundance increase after fertilization, which will facilitate the control of ARGs and ARB dissemination.

Abstract
High concentrations of total arsenic (As), even above the Brazilian legislative threshold for marine sediments of 70 mg kg-1, were found in beach sands and near-shore surface sediments. Two mechanisms (anthropogenic activities and sedimentary processes in the coastal waters) are responsible for this contamination. The anthropogenic impact includes releases from metallurgical plants, phosphate fertilizer plants and gold and iron mining. In the coastal area sedimentary processes redistributed the As from the sediment into the porous structure of calcareous marine algae. These enriched calcareous algae are transported over time to the beach by wave action. As in the Brazilian coastal environment, increased As levels were also observed in other coastal environments of South America such as Rio Loa (Chile), Barbacoas Bay (Colombia) and the Southern Pampa region (Argentina). Finally, arsenic levels in fish from Brazilian coastal waters and North Sea, which is also an As-contaminated area, were compared. In both areas, short term health effects from fish consumption are not expected, but a lifetime cancer risk cannot be excluded.
