摘要

[Objective] The aim was to study the distribution and its ecological risks of heavy metal in the sediments of the polluted coastal regions in Bohai Bay, Changjiang and Zhujiang estuaries. [Method] The economic activities had great influence on the Bohai Bay, Changjiang and Zhujiang estuaries. The pollution of different heavy metals in the deep ocean was summarized by summary of the relation between the distribution of heavy metals and economic activities. [Result] In general, influenced by economic development, the heavy metal pollution in coastal area in China was pessimistic. The sediments in the Bohai Bay, Changjiang and Zhujiang estuaries showed different degrees of Cd, Cr, Zn, Cu and Pb pollution. As pollution in Bohai Bay and Zhujiang estuaries can not be neglected. The heavy metal pollution may pass into human body with the transportation of food chain. [Conclusion] The study provided reference for the formulation of policies to restrain heavy metal emission and protection of human health.
