Lipid peroxidation and metallothionein induction by chromium and cadmium in Oyster Crassostrea virginica (Gmelin) from Mandinga Lagoon, Veracruz

Metallothionein and lipid peroxidation are associated to metals toxicity, it is possible that accumulation in tissue might as well be related to their increase. Both biomarkers under Cr and Cd exposure were evaluated in the American oyster Crassostrea virginica (Gmelin) by Semi-static bioassays, 96...
