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.

利用代表性物种Mytrous trossulus评价海洋环境质量的不同生物标志物

贻贝贻贝被用来评估生物标志物的反应与环境污染程度之间的关系，以及它们在生物监测中的潜在用途。在Zolotoy Rog湾和Vostok湾（日本海的彼得大帝湾）的贻贝中测量了金属生物蓄积量和一系列生物标志物，显示出污染水平的实质差异。生物标志物包括溶酶体膜稳定性（LMS）。条件指数（CI和CIL）；过氧化氢酶（CAT），谷胱甘肽-S-转移酶（GST）和乙酰胆碱酯酶（AChE）的活性；以及脂质过氧化的水平（硫代巴比妥酸反应性物质，TBARS），蛋白质氧化（蛋白质羰基，PC）和DNA损伤。在为分子水平M. trossulus，氧化应激（CAT，TBARS和PC）和AChE的生物标志物未显示已知程度的环境污染。同时，生物标志物的LMS和状态指数以及生物标志物的GST和DNA损伤对复杂的慢性环境污染敏感。
