Glutathione, glutathione-dependent and antioxidant enzymes in mussel, Mytilus galloprovincialis, exposed to metals under field and laboratory conditions: implications for the use of biochemical biomarkers
TL;DR: In this article, the effects of exposure to metals under and laboratory conditions were investigated in the Mediterranean mussel Mytilus galloprovincialis, including the concentrations of heavy metals, the level of glutathione, and the activity of several enzymes selected among glutathion-dependent oxidoreductases and hydrolases.

Induction of cytochrome P450 as a biomarker for environmental contamination in aquatic ecosystems
Thomas D. Bucheli,Karl Fent +1 more
TL;DR: Application of the induction of cytochrome P4501A (CYP1A), certainly the best studied biomarker, in field trials with freshwater and marine fish is reviewed and shows that CYP1A induction is significantly related to contaminant levels in the environment in 93% of the investigated field studies.
Journal ArticleDOI
Effects of chronic exposure of 2,4-dichlorophenol on the antioxidant system in liver of freshwater fish Carassius auratus.
TL;DR: Good dose-effect relations were found between 2,4-DCP level and CAT activity, GSSG content, Se-GPx activity, respectively, and SOD and Se- GPx may be potential early biomarkers of 2,3-dichlorophenol contamination in aquatic ecosystems, and further studies will be necessary.
Journal ArticleDOI
Antioxidant enzymes and peroxisome proliferation in relation to contaminant body burdens of PAHs and PCBs in bivalve molluscs, crabs and fish from the Urdaibai and Plentzia estuaries (Bay of Biscay).
TL;DR: The estuaries of Urdaibai and Plentzia can be considered as low to moderately polluted areas and levels of PAHs and PCBs do not show marked variations apart from seasonal variations.
Journal ArticleDOI
Oxidative stress in gill, erythrocytes, liver and kidney of Nile tilapia (Oreochromis niloticus) from a polluted site
TL;DR: Comparisons between some pro- and antioxidant parameters in erythrocyte, gill, liver and kidney of Nile tilapia, O. niloticus and from a polluted site in the Billings Reservoir provide useful data for future investigations of polluted aquatic sites to provide a data base relating the presence of pollutants to biological effects at a molecular level.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.

TL;DR: In this paper, the levels of four sets of pollutants (heavy-metals, artificial radionuclides, petroleum components, and halogenated hydrocarbons) have been measured in U.S. coastal waters, using bivalves as sentinel organisms.

Oxyradical production as a pollution-mediated mechanism of toxicity in the common mussel, Mytilus edulis L., and other molluscs
TL;DR: In this paper, normal and pollution-enhanced oxy- radical (02-, H202, OH) production in molluscs have been reviewed and discussed, and data are presented on the antioxidant enzyme responses and lipid peroxidation effects in diges- tive gland of Mytilus edulis L. exposed to 50p.p.b. benzo(a)pyrene (BaP) or 1 p.m.

Tissue and subcellular distribution of enzyme activities of mixed-function oxygenase and benzo [a] pyrene metabolism in the common mussel Mytilus edulis L.
TL;DR: A cytochrome P-450 mediated MFO system is present in mussels and an observed relationship between microsomal BP hydroxylase and NADPH-cytochrome c reductase activities is concluded.
