Using of biochemical markers in active monitoring of contaminated marine environment
Mussels from Vostochnaya Bay, a reference site in the Peter the Great Bay of the East Sea, were transplanted to contaminated Desantnaya Bay for 30 days. As biochemical indices, superoxide dismutase (SOD), catalase, glutathione reductase, total oxyradical scavenging capacity (TOSC), glutathione, lipid peroxidation products were measured in mussel digestive gland and gills. Biomarker responses varied between indigenous and transplanted animals. In transplanted mussels, the lipid peroxidation process in digestive gland was significantly stimulated (the level of conjugated dienes increased 2.5-fold; malondialdehyde — 2-fold and lipofuscin contents were increased 4-fold). The total oxyradical scavenging capacity in digestive gland fell by 50 %, whereas contents of glutathione increased 2-fold.
