“…However, our previous study reported the concentration ranges of 45.7 to 1743 ng/L for OCPs and 0.051 to 4.32 ng/L for PCBs in the investigated Dongjiang River basin . In addition, the effects of metals or steroid hormones on EROD activity and CYP1A mRNA expression cannot be ignored, where mosquitofish are exposed to complex mixtures including metals and steroid hormones in the two rivers , Huang et al, 2013Huang et al, 2012;Lavado et al, 2006;Ying et al, 2012). It is noted in the present study that the correlations between EROD activity and CYP1A mRNA expression appear to be sex specific, which might be due to sex-related differences in P450 activity.…”

“…Among the available techniques, the use of biomarkers based on variations at the morphological, cellular and molecular levels in indicator species appears as a valuable tool to detect environmental stress of multiple contaminants in aquatic environments (Fernandes et al, 2007;Frenzilli et al, 2008;Lavado et al, 2006). Assessment of biomarkers in fishes can act as an early warning system predicting the pollution effects (Mierzejewski et al, 2014).…”

“…Another important issue that has to be considered here is the fact that certain ubiquitous contaminants as pharmaceuticals (diclofenac, carbamazepine, clofibrate etc. ), organochlorine residues and some metallic contaminants (organotins, mercury) were proven to inhibit the CYP-like enzymes and associated mixed function oxidase components (Thibaut et al, 2006;Lavado et al, 2006;Edwards et al, 2007;Faria et al, 2010) in several biological models. Thus, for sites as harbours, which are usually affected by complex mixtures of contaminants, the antagonism of chemicals on the EROD activity of aquatic biota might also be expected.…”

Stress biomarkers, which can outline impacts of contaminants in aquatic biota at the biochemical level, are increasingly used as early warning tools in environmental monitoring. Reliable biomarker based assessment schemes, however, request appropriate knowledge of baseline levels of selected endpoints, and the potential influence of a range of natural influencing factors (both abiotic and biotic) as well. In this study, we examined the interspecies variability of various biomarkers (metallothioneins (MT), ethoxyresorufin-Odeethylase activity (EROD), lipid peroxidation (LPO), DNA strand breaks (DNA_sb), vitellogenin-like proteins (Vtg)) in Dreissena polymorpha and Dreissena bugensis inhabiting either pristine-or moderately impacted sites of Lake Balaton (Hungary). Levels of all biomarkers considered revealed low interspecies variability in the two dreissenid species at all sampling sites, with consistently higher (but statistically insignificant) values in Dreissena polymorpha. Levels of all biomarkers varied within the two investigated seasons, with significant influence of the reproduction cycle particularly on the levels of metallothioneins and vitellogenin-like proteins. Each biomarker considered was elevated by October, with significantly higher values in the mussels inhabiting harbours. Insignificant spatial and temporal variability in the general health indicators (condition index, total protein content) of dreissenids was observed, which, in parallel with evident rise in biomarker levels, apparently suggest that the anthropogenic impacts in harbours affect mussel fitness yet at sub organismal level. Our data might serve useful basis for future environmental monitoring surveys, especially in habitats where the progressive replacement of Dreissena polymorpha by Dreissena bugensis is taking place, as the interspecies variability in susceptibility to chemical stress of the two species is well comparable.

“…Biochemical response capacities of defense system enzymes such as biotransformation system phase II enzyme glutathione-S-transferase (GST), the antioxidative enzymes such as catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD) provide results that are sensitive, informative, reproducible and can indicate potential toxicity in organisms such as fish, bivalves, aquatic worms, African common toad, mussels exposed to toxicant [14][15][16][17]. Some evidences indicate that the induction of the CAT activity is considered valid biomarkers of ambient oxidative pollutants in earthworm toxicology [18][19][20].…”

The survival, growth, activity of the biotransformation system phase II enzyme glutathione-S-transferase (GST) and the oxidative defense enzyme catalase (CAT) of earthworms exposed to the contaminated soils from a former DDT plant and reference soils were investigated, and compared with the corresponding indicators in simulated soil-earthworm system, unpolluted natural soils with spiked-in DDT series, to identify the toxic effects of DDT on earthworms and their cellular defense system in complex soil system. The results indicated that DDT level in the contaminated soils was significantly higher than that in the reference soils with similar level of other pollutants and soil characters. The mortality, growth inhibition rates, GST and CST activities of earthworms exposed to the contaminated soils were significantly higher than that in reference soils. The contribution of historical DDT in contaminated soils to earthworms was confirmed by the DDT spiked tests. DDT spiked in soils at rates of higher than 200 mg·kg −1 was significantly toxic to both the survival and the growth of earthworms. DDT significantly stimulated GST and CAT activity in earthworms after 14 days. The CAT and GST activities were also stimulated by DDT exposure at rates of 100 mg·kg −1 after chronic exposure (42 days). The results provide implications for validating the extrapolation from laboratory simulated soils criteria to contaminated soils and for making site risk assessments.
