Effects of copper on lipid peroxidation,glutathione,metallothionein, and antioxidative enzymes in the freshwater mussel Anodonta anatina
Copper is an essential element to all animals. At elevated concentrations, it is toxic and can participate in the formation of reactive oxygen species, leading to cellular damage.

| Summary: | Copper is an essential element to all animals. At elevated concentrations, it is toxic and can participate in the formation of reactive oxygen species, leading to
cellular damage. In this study, the ecotoxicological relevance of copper was investigated with freshwater mussels, Anodonta anatina. When the mussels were
exposed to copper at environmentally realistic concentrations, either via the water (0.3 mmol L1 Cu) or fed with Cu-loaded algae (equivalent to 0.06 mmol L1 Cu),
the level of thiobarbituric acid-reactive substances rose and glutathione decreased. This was associated with the induction of metallothionein and, relative to total protein, of glutathione reductase and the antioxidative enzymes superoxide dismutase, catalase, and glutathione peroxidase. But, since the overall protein-synthetic capacity was hampered by the copper insult, the activities of the enzymes relative to tissue weight and copper concentrations were depressed.
During depuration, most parameters started to normalize although not returning to control values within 12 days. |
