The Different Biomarkers in the Assessment of the Marine Environmental Quality Using the Representative Species Mytilus trossulus

2020

The mussel Mytilus trossulus was used to assess the relationship between the reactions of biomarkers and the degree of environmental pollution, as well as their potential use in biomonitoring. Metal bioaccumulation and a battery of biomarkers were measured in the mussels from the Zolotoy Rog Bay and Vostok Bay (Peter the Great Bay, the Sea of Japan) that display substantial differences in the levels of pollution. The biomarkers included lysosomal membrane stability (LMS); condition indices (CI and CIL); the activities of catalase (CAT), glutathione-S-transferase (GST) and acetylcholinesterase (AChE); and the levels of lipid peroxidation (thiobarbituric acid reactive substances, TBARS), protein oxidation (protein carbonyls, PC), and DNA damage. At the molecular level for M. trossulus, the biomarkers of oxidative stress (CAT, TBARS, and PC) and AChE do not show a known degree of environmental pollution. At the same time, the biomarkers LMS and condition indices, as well as the biomarkers GST and DNA damage, are sensitive to complex chronic environmental pollution.
