The present study was mainly focused on the distribution of metals (Cd, Cu, Pb, and Zn) in commercially important marine finfish and shellfish resources collected from the Tuticorin coast of the Gulf of Mannar, Southeastern India. Sixty-six species were collected in all four seasons for the analysis of metals. The order of bioaccumulation of metals in fishes is (Zn > Pb > Cu > Cd), in Crustaceans is (Zn > Pb > Cu > Cd), and in mollusks is (Pb > Zn > Cu > Cd). The human health risk assessment factors such as BCF, THQ, and HI were higher in most of the tested animals. The outcome of the present study will sound the alarm to the community about heavy metal contamination of sea foods. We conclude that continuous monitoring of the ecosystem is essential to the maintenance of the pristine ecosystem and quality of the seafood.

本研究主要集中在从印度东南部曼纳尔湾杜蒂戈林海岸收集的具有商业意义的重要有鳍鱼类和贝类资源中金属（镉，铜，铅和锌）的分布。在所有四个季节中收集了66种物种用于金属分析。鱼类中金属的生物累积顺序是（Zn> Pb> Cu> Cd），甲壳类动物是（Zn> Pb> Cu> Cd），软体动物中是（Pb> Zn> Cu> Cd）。在大多数测试动物中，人类健康风险评估因素（例如BCF，THQ和HI）较高。本研究的结果将向社会发出有关海鲜中重金属污染的警报。我们得出结论，持续监测生态系统对于维持原始生态系统和海产品质量至关重要。
