چکیده انگلیسی
Metallothionein level (MT), and acetylcholinesterase (AChE), catalase (CAT) and glutathione-S-transferase (GST) enzyme activities in the bivalves Mytilus edulis and Macoma balthica were investigated for seasonal variations from an inshore and an offshore site in the northern Baltic Sea. All the biomarkers showed variability, following mostly a similar pattern at both sites. Relationships between biomarkers and environmental factors and protein concentration and weight of target tissues were examined. In M. edulis, GST activity was related to Secchi depth, while in M. balthica a correlation with near-bottom oxygen saturation was observed. AChE activity correlated with the weight of the foot tissue of M. balthica. In both species, an integrated biomarker index indicated a stressed condition during the spring/early summer period. Strong seasonal variability in temperature and a concentrated period of food availability in spring-both governing the reproductive cycle of the bivalves-probably explains most of the observed natural variability in biomarkers in this sea area.
