Abstract
In the present study, the environmental changes over the past 100 years in the Cambé River watershed in Southern Brazil were investigated. For this, a sediment core was collected to examine the distribution of metals, polycyclic aromatic hydrocarbons (PAHs), and ecotoxicological markers. The core corresponds from 1914 to 2012, which was obtained by the decay of 210Pb. Changes in the study area also were examined by: Geoaccumulation index (Igeo) and enrichment factor (EF), sediment quality guidelines (SGQs), and ethoxyresorufin-O-deethylase (EROD) activity in Poeciliopsis lucida hepatocellular carcinoma (PLHC-1) cells line. The Σ16 PAHs ranged from 242.6 to 40,775 ng g-1, with pyrogenic source at the beginning of the core, which likely corresponds to the burning of forests to establish the city and the later use of fossil fuels from 1960 to 2012. In the 1930s, most of metals presented a concentration below the background. After the 1930s, high concentrations can be associated with the intense use of fertilizers (Cd, Cu, Zn, Hg) and increases in urban traffic (Zn and Pb). Igeo showed that the distribution of Cu is considered moderately to strongly polluted, and the EF of Pb was considered as moderately polluted. Statistical analyses showed a strong relation between the presence of the ANP, FLU, PHE, BaP, IND, and Bghi compounds and the induction of EROD activity, and no correlation with heavy metals. A prediction model for the linear regression was obtained between the ANP and BaP concentrations and the EROD activity, with an accuracy of 99%.

Abstract
The environmental quality of marine sediments collected in the area of influence of the Po and Danube Rivers was assessed by using a battery of bioassays based on the use of PLHC-1 cells, zebrafish-Pxr-transfected COS-7 cells, and sea bass ovarian subcellular fractions. This allowed the determination of multiple endpoints, namely, cytotoxicity, oxidative stress, induction of CYP1A, activation of zebrafish Pxr and inhibition of ovarian aromatase. Organic extracts of sediments influenced by the Danube River and collected near harbors and urban discharges showed significant cytotoxicity, CYP1A induction and inhibition of aromatase activity. An analogous response of CYP1A induction and zfPxr activation was observed, which suggests the existence of common ligands of AhR and PXR in the sediment extracts. The study highlights the usefulness of the selected bioassays to identify those sediments that could pose a risk to aquatic organisms and that require further action in order to improve their environmental quality.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are often detected in the environment and are regarded as endocrine disruptors. We here designated mixtures of PAHs in the environment as environmental PAHs (ePAHs) to discuss their effects collectively, which could be different from the sum of the constituent PAHs. We first summarized the biological impact of environmental PAHs (ePAHs) found in the atmosphere, sediments, soils, and water as a result of human activities, accidents, or natural phenomena. ePAHs are characterized by their sources and forms, followed by their biological effects and social impact, and bioassays that are used to investigate their biological effects. The findings of the bioassays have demonstrated that ePAHs have the ability to affect the endocrine systems of humans and animals. The pathways that mediate cell signaling for the endocrine disruptions induced by ePAHs and PAHs have also been summarized in order to obtain a clearer understanding of the mechanisms responsible for these effects without animal tests; they include specific signaling pathways (MAPK and other signaling pathways), regulatory mechanisms (chromatin/epigenetic regulation, cell cycle/DNA damage control, and cytoskeletal/adhesion regulation), and cell functions (apoptosis, autophagy, immune responses/inflammation, neurological responses, and development/differentiation) induced by specific PAHs, such as benz[a]anthracene, benzo[a]pyrene, benz[l]aceanthrylene, cyclopenta[c,d]pyrene, 7,12-dimethylbenz[a]anthracene, fluoranthene, fluorene, 3-methylcholanthrene, perylene, phenanthrene, and pyrene as well as their derivatives. Estrogen signaling is one of the most studied pathways associated with the endocrine-disrupting activities of PAHs, and involves estrogen receptors and aryl hydrocarbon receptors. However, some of the actions of PAHs are contradictory, complex, and unexplainable. Although several possibilities have been suggested, such as direct interactions between PAHs and receptors and the suppression of their activities through other pathways, the mechanisms underlying the activities of PAHs remain unclear. Thus, standardized assay protocols for pathway-based assessments are considered to be important to overcome these issues.

In vitro bioassays for detecting dioxin-like activity--application potentials and limits of detection, a review. THE SCIENCE OF THE TOTAL ENVIRONMENT 2014; 487:37-48.

Abstract
Use of in vitro assays as screening tool to characterize contamination of a variety of environmental matrices has become an increasingly popular and powerful toolbox in the field of environmental toxicology. While bioassays cannot entirely substitute analytical methods such as gas chromatography-mass spectrometry (GC-MS), the increasing improvement of cell lines and standardization of bioassay procedures enhance their utility as bioanalytical pre-screening tests prior to more targeted chemical analytical investigations. Dioxin-receptor-based assays provide a holistic characterization of exposure to dioxin-like compounds (DLCs) by integrating their overall toxic potential, including potentials of unknown DLCs not detectable via e.g. GC-MS. Hence, they provide important additional information with respect to environmental risk assessment of DLCs. This review summarizes different in vitro bioassay applications for detection of DLCs and considers the comparability of bioassay and chemical analytically derived toxicity equivalents (TEQs) of different approaches and various matrices. These range from complex samples such as sediments through single reference to compound mixtures. A summary of bioassay derived detection limits (LODs) showed a number of current bioassays to be equally sensitive as chemical methodologies, but moreover revealed that most of the bioanalytical studies conducted to date did not report their LODs, which represents a limitation with regard to low potency samples.

Abstract
This study characterizes the environmental quality of sediments from the Arade and Guadiana estuaries using different in-vitro bioassays: a) fish hepatoma cell line (PLHC-1) to determine cytotoxicity and presence of CYP1A and oxidative stress inducing agents; b) gonad subcellular fractions from sea bass (Dicentrarchus labrax) to detect compounds that are likely to act as endocrine disrupters by interfering with the synthesis of androgens (CYP17, CYP11β) and estrogens (CYP19). Approximately 60% of extracts from the Arade estuary were cytotoxic when tested at 60 mg eQsed/mL, while only one sample from Guadiana showed cytotoxicity. Sediments from Arade collected close to harbours and waste water effluents were enriched with CYP1A inducing agents, while those from the upper Guadiana induced oxidative stress in PLHC-1 cells. On the other hand, several extracts from both estuaries were able to significantly inhibit CYP17, CYP11β and CYP19 activities in gonad subcellular fractions of sea bass, which indicates the presence of endocrine disrupters, particularly in several sites from the Arade estuary. Overall, the study highlights the usefulness of in-vitro bioassays to identify those sediments that could pose risk to aquatic organisms and that require further action to improve their environmental quality.

Abstract
In North-East Estonia, considerable amounts of toxicants (e.g. polycyclic aromatic hydrocarbons (PAHs), phenols, heavy metals) leach into water bodies through discharges from the oil-shale industry. In addition, natural and anthropogenic hypoxic events in water bodies affect the health of aquatic organisms. Here we report a study on the combined effects of contaminated sediment and hypoxia on the physiology of gibel carp (Carssius auratus gibelio). We conducted a laboratory exposure study that involved exposure to polluted sediments from oil-shale industries (River Purtse) and sediments from a relatively clean environment (River Selja), together with sediments spiked with PAHs. The oxygen content (saturation vs. hypoxia (< 2 mg/L)) was changed to reflect hypoxia. A multi-biomarker approach was chosen to enable the combined effects to be assessed comprehensively and integratively. We used HPLC to measure the PAH concentration in sediment and fish muscle, fixed wavelength fluorescence (FF) analyses to indicate the presence of PAH metabolites in fish bile, and nuclear abnormalities in erythrocytes as markers of geno- and cyto-toxicity; and we monitored the change in body condition and measured EROD activity to indicate CYP1A induction. High levels of PAH conjugates in fish bile were found in the group exposed to the Purtse River sediment under hypoxia. The results suggested that induction of the CYP1A gene was modulated by hypoxia as well as by heavy metals. We found a correlation between several erythrocyte abnormalities (8-shaped nuclei and blebbed nuclei) and PAH metabolite content in fish. In conclusion, a measurable effect of pollution from the oil-shale industry on fish health parameters was clear under different oxygen levels.

Abstract
The responsiveness of CYP1A (gene transcription and EROD enzyme activity) in the cell line Poeciliopsis lucida hepatoma (PLHC-1) upon exposure to extracts of contaminated soil samples was investigated and compared to levels of PCDD/PCDFs and PCBs including non-ortho obtained by GC/MS analysis. Soil samples A and B were collected in sites A and B. Two fractions, not purified (np) and purified (p), were obtained from each sample and analyzed for PCDD/PCDF and PCB content by GC/MS; in parallel they were tested for 24 h with PLHC-1. CYP1A response was investigated at gene (RT-qPCR) level and as 7-ethoxyresorufin-O-deethylase (EROD) enzyme activity. Chem-TEQs and Bio-TEQs were then calculated. ∑TEQ calculated for PCDD/Fs and PCBs was 0.081 pg/g and 20.32 pg/g for samples A and B, respectively. PLHC-1 showed less up-regulation of cyp1a gene on exposure to the two purified fractions (Ap 2.1-fold and Bp 1.8-fold) than to non-purified fractions (up to 15-fold for Anp and 13-fold for Bnp). EROD was also induced 2.38- and 9.44-fold in the two purified fractions (Ap and Bp) compared to model inducer 2,3,7,8-TCDD, and up to 16.03-fold for non-purified Anp and 33.79-fold for Bnp. The combination of CYP1A response, obtained in a PLHC-1 cell-based bioassay, with contaminant residue analysis provided a better description of the presence and toxicity of dioxin-like compounds in an environmental matrix.

Abstract
The Mediterranean region includes many small coastal rivers about which little is known concerning organic contaminant loads in their sediment. This study was designed to assess organic contamination in one of these small coastal rivers (Lez River) and associated coastal sediments. Levels of alkylphenols (APs), polycylic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) were measured in sediments of the Lez River and two coastal lagoons impacted by wastewater discharges. In parallel, sediment surrounding a recently built submarine outfall that discharges treated wastewater, from an area encompassing some 450,000 inhabitants, into the sea was monitored a year after the beginning of emission via the outfall. Finally, these sediments were characterized by screening estrogenic, PAH-like and dioxin-like activities using in vitro bioassays. Both chemical analyses and bioassays revealed that wastewater inputs were a source of organic contamination of sediments from the Lez and lagoons, which still persisted 2 years after the discharges were stopped. APs could explain a small proportion of the overall estrogenic activities (up to 31%), suggesting that other estrogenic compounds were also present in the sediments. PAHs explained a great share (83% on average) of the EROD induction potency of the extracts. This survey should be the first step in the long-term monitoring of these sites.

The aim of this work was to evaluate the induction of protoporphyrins IX (PpIX) activity and superoxide anions (SO) in human leukocytes exposed to anthracene (ANT) and benzo(a)pyrene (B(a)P). The leukocyte LC(50)s for both hydrocarbons and the PpIX accumulation and SO overproduction were measured. The LC(50)s were 0.35 and 3.23μM for ANT and B(a)P, respectively. A linear relationship (r=0.97, p<0.01) between PpIX and ANT concentration was obtained. The induced accumulation of PpIX was proportional (r=0.63, p<0.01) to B(a)P concentration. SO overproduction showed a linear relationship (r=0.83, p<0.05) with ANT concentrations. The linear regression analysis of the effect of B(a)P on the superoxide anion overproduction showed a good coefficient (r=0.97, p<0.01), showed that ANT and B(a)P exposure induces PpIX accumulation, probably by disruption of the haem biosynthesis. ANT and B(a)P induce SO overproduction, perhaps through a process of redox cycling.

Abstract
In the present study, we assess the potential of fish cell lines (CHSE, EPC and RTG-2) to be used as screening tools for the ecotoxicological assessment of estuarine sediments. The processing of sediment to a form suitable for in vitro exposure is an inherent problem when using cell cultures. The approach employed in this study was to prepare aqueous elutriate extracts from whole sediments, which were subsequently used to reconstitute powdered media. This procedure allowed the exposure of cell cultures to concentrations of up to and including 100% of the original aqueous sample. Cytotoxicity was assessed using multiple endpoint measurements. Cell viability was quantified using the neutral red and alamar blue colorimetric assays, which specifically assess lysosomal and mitochondrial function, respectively. In addition, the total protein content of the cells was measured using the coomassie blue assay. Initial tests were conducted to ensure that any resultant cytotoxicity was due to sample contaminants and not osmotic stress. In addition, elutriate samples were spiked with a model toxicant to verify the ability of the cell lines to detect and respond to bioavailable contaminants. Chemical analyses were conducted on sediments from all sampling sites to assist in interpreting any observed cytotoxicity. A differential response was observed for the cytotoxicity assays following exposure treatments, which emphasises the importance of employing multiple endpoints for the determination of toxicity. Of the three cell lines utilised in this study, RTG-2 cells were the most suitable for the testing of estuarine aqueous elutriate samples on the basis of tolerance to osmolality effects. Slight toxicity was observed following exposure to the aqueous elutriates tested in this study using RTG-2 cells and the alamar blue assay. In order to fully evaluate the overall sensitivity of this cell line, further research is warranted using an extensive range of test sites incorporating more polluted sediments.

Abstract
Heterocyclic polyaromatic compounds, including dinaphthofurans, 2-(2-naphthalenyl)benzothiophene, methylated chrysene, and benz[a]anthracene, were identified and confirmed as major cytochrome P4501A (CYP1A)-inducing compounds in a contaminated sediment close to the industrial site of Bitterfeld (Germany). Identification was achieved by the application of an effect-directed fractionation and analysis approach. This approach comprised the combination of a rainbow trout liver cell line (RTL-W1) bioassay to select for CYP1A-inducing effects by measuring 7-ethoxyresorufin-O-deethylase activity, a multistep fractionation procedure, and various methods of chemical characterization. The identified nonpriority pollutants were found to be significantly more potent than the reference compound, benzo[a]pyrene, and among the most potent polycyclic inducers known. On the basis of the history of industrial activity at the contaminated site, the heterocyclic compounds identified in this study are thought to stem from 2-naphthol production. 2-Naphthol is one of the most high-tonnage products of the aniline dye industry in general, thereby indicating the potential environmental relevance of the identified heterocyclic aromatic compounds. To date, however, no or very little knowledge exists about their occurrence, fate, and biological effects.

Abstract
Aryl hydrocarbon receptor (AHR) ligands such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) cause altered cell proliferation in many tissues in vivo and cell types in vitro, and the AHR has been suggested to play a role in cell cycle regulation in mammalian systems. However, the mechanisms underlying these effects are poorly understood. The overall objective of the present work was to investigate possible interactions between cell proliferation, the cell cycle, and AHR signal transduction in a piscine system, the PLHC-1 cell line, which is being used increasingly in aquatic toxicological research. The specific objectives were to characterize proliferation rates and the cell cycle in these cells, to measure effects of TCDD on cell proliferation, and to determine if expression of the AHR varies during the cell cycle. The doubling time of PLHC-1 cells was determined to be 22 h, and the durations of the G1, S and G2/M stages of the cell cycle were 13, 3, and 6 h, respectively. A minimum seeding density of 1.2 x 10(5) cells/cm(2) in medium with 10% calf serum and 0.3 x 10(5) cells/cm(2) in 10% fetal bovine serum was found to be required for subsequent proliferation. Of several cell cycle inhibitors tested, only aphidicolin and nocodazole were effective for obtaining synchronous cell populations. TCDD was found to inhibit PLHC-1 cell proliferation in a time- and dose-dependent manner in multiple passages of one sub-clone, but not in several other sub-clones. Neither AHR mRNA nor protein expression varied during the cell cycle, as measured by RT-PCR and specific binding of [(3)H]TCDD in synchronous PLHC-1 cells. This work establishes techniques for identifying and characterizing possible interactions between the cell cycle and AHR signal transduction in PLHC-1 cells. Taken together, the results indicate that PLHC-1 cells are amenable to analysis of AHR-cell cycle interactions, but that heterogeneity of sub-clones may complicate their use for investigating AHR-mediated changes in proliferation.

Abstract
The oil-shale industry has created serious pollution problems in northeastern Estonia. Untreated, phenol-rich leachate from semi-coke mounds formed as a by-product of oil-shale processing is discharged into the Baltic Sea via channels and rivers. An exploratory analysis of water chemical and microbiological data sets from the low-flow period was carried out using different multivariate analysis techniques. Principal component analysis allowed us to distinguish different locations in the river system. The riverine microbial community response to water chemical parameters was assessed by co-inertia analysis. Water pH, COD and total nitrogen were negatively related to the number of biodegradative bacteria, while oxygen concentration promoted the abundance of these bacteria. The results demonstrate the utility of multivariate statistical techniques as tools for estimating the magnitude and extent of pollution based on river water chemical and microbiological parameters. An evaluation of river chemical and microbiological data suggests that the ambient natural attenuation mechanisms only partly eliminate pollutants from river water, and that a sufficient reduction of more recalcitrant compounds could be achieved through the reduction of wastewater discharge from the oil-shale chemical industry into the rivers.

Abstract
The present review describes international activities using bioassays/biomarkers in combination with chemical analysis to measure the effects of dioxin and dioxin-like compounds (DLCs) in the environment. The above authors reviewed already the state-of-art bioanalytical detection methods (BDMs) for dioxins and DLCs [Environ Int (2001)]. The aim of this study will be to review applications of these bioassays/biomarkers to evaluate potential dioxins and DLCs. The present literature study lists relative potencies (REPs) of polyhalogenated dibenzo-p-dioxins and -furans (PXDD/Fs; X = Cl, Br, F), their thio analogues polychlorinated dibenzothiophenes (PCDTs) and thianthrens (PCTAs), polyhalogenated biphenyls (PXBs), polychlorinated naphthalenes (PCNs) and other Ah receptor agonists measured by several biodetectors (Tier 3 screening). The authors will discuss some examples of the applications of some of these biodetectors in biomonitoring programmes and recently occurred dioxin crisis in feed/food. The diagnosis of the biopotency of these pollutants in technical processes like thermally treated waste, waste water treatment, landfill leachate treatment, commercial PCB-mixtures, the release into the environment (soil, air and water) and the final intake into wildlife and humans will be reviewed.

Abstract
In vitro systems such as primary cells and cell lines are of growing importance in ecotoxicology. Cells from different tissues and species of fish are used for the assessment of toxic action of chemicals and evaluation of environmental samples. For organotins and substituted phenols, we have found that the in vitro cytotoxicity is positively correlated with the acute toxicity in vivo, and therefore cytotoxicity assays may serve as an alternative for acute fish toxicity testing. We have been using the hepatocellular carcinoma (PLHC-1) cell line for the assessment of the cytochrome P4501A (CYP1A) induction potential of polyaromatic hydrocarbons (PAHs), nitro-PAHs and azaarenes. For these compounds, the CYP1A induction potential is found to be related to the molecular structure and lipophilicity. In mixtures, CYP1A induction of individual compounds is additive. Based on the comparative investigation of the induction potential we derived an induction equivalency (IEQ) concept that can be applied for the evaluation of environmental samples such as landfill leachates, sediments and motorway runoffs. Fish cell lines are also valuable, rapid and cost-effective tools for the assessment of estrogenic activity of chemicals and environmental samples. We have developed an estrogen-responsive reporter gene system using the rainbow trout gonad cell line RTG-2, in which an estrogen receptor beta form is expressed at very low levels, but is not inducible. As the estrogenic activity is dependent on the cellular level of estrogen receptor (ER), ER has to be co-transfected in transient transfections in addition to an estrogen-responsive reporter gene. Using a dual luciferase system, the estrogenic activity of 12 compounds including alkylphenols, DDT-isomers and its metabolites have been assessed. Our system shows a high sensitivity with a detection limit of 0.05 nM estradiol and is therefore more sensitive than many other mammalian or yeast systems. The relative estrogenic activity (e.g. o,p'-DDT) and other toxicological effects may differ from those in mammalian systems, indicating that a risk evaluation for fish could only be meaningfully assessed in fish-specific systems. This paper illustrates the versatility and high potential of fish cell lines in ecotoxicology.

Abstract
Nitrated polycyclic aromatic hydrocarbons (NPAHs) and N-heterocyclic aromatic hydrocarbons (azaarenes) are as ubiquitous in the environment as their parent PAH compounds, although occurring at lower concentrations. The toxicological importance of NPAHs and azaarenes is based on their mutagenic and carcinogenic potential. Azaarenes possess a higher solubility and mobility in the environment than PAHs. However, very little is known about the toxicity and cytochrome P450 (CYP)1A induction potencies of NPAHs and azaarenes in fish. Here we report on the cytotoxicities and relative CYP1A induction potencies of 12 NPAHs, 12 azaarenes, and 11 PAHs, determined as neutral red uptake and ethoxyresorufin-O-deethylase (EROD) activity, respectively, in fish hepatoma PLHC-1 cells. Additionally, CYP1A enzyme protein was determined by ELISA for two NPAHs, azaarenes, PAHs, and binary mixtures. Compared with the structurally analogous PAHs, 2-nitronaphthalene, 3-nitrofluoranthene, 2-aza- and 7-azafluoranthene, 1,6-dinitropyrene, benzo[a]acridine and benzo[h]quinoline revealed higher induction potencies, whereas the other compounds showed similar or less activity. The induction potency was highly dependent on the compounds structural properties, reflected by significant correlations between the half-maximal EROD induction (-log EC50) and the molecular descriptors lipophilicity (log Kow) and maximal molecular length (Lmax). Binary mixtures of 6-nitrochrysene + benzo[a]anthracene, 6-nitrochrysene + benzo[a]acridine, and benzo[a]acridine + benzo[a]anthracene showed an additive interaction. The CYP1A induction potencies of NPAHs and azaarenes, demonstrated here for the first time in fish hepatoma cells, suggest that their contribution to the overall CYP1A induction potencies in PAH-contaminated environmental samples have to be taken into account.
