- Low oxygen stress alters response to sublethal copper exposure without inducing cross-tolerance in the blue mussel Mytilus edulis. Janardhanan, Reshma Kalarical Nachev, Milen Sures, Bernd Sokolova, Inna M Mytilus edulis Copper Water Pollution, Chemical Water Pollutants, Chemical Oxygen Hemocytes Electron Transport Gills Oxidative Stress Animals The Baltic Sea's limited water exchange and densely populated catchment area contribute to the frequent co-occurrence of hypoxia and chemical pollutants such as copper (Cu), raising concerns about the effects of sequential stressors on marine organisms. This study tested whether pre-exposure to intermittent oxygen stress alters the physiological and immune responses of Mytilus edulis to subsequent Cu exposure. Mussels were preconditioned for 21 days to either mild intermittent hypoxia (7 h/day at ∼2 mg/L DO) or severe intermittent anoxia (2 days/week at
