溶解性有机质对有机污染物生物有效性影响

Effect of Dissolved Organic Matter on the Bioavailability of Organic Pollutants

溶解性有机质(DOM)是水体环境中重要的组成部分,由于其特殊的物理化学结构,往往能够影响污染物的环境行为归趋。有机污染物是目前水体环境中广泛存在的一类污染物质,具有较强的生物毒性,易通过食物链累积,对生态系统和人类健康构成威胁。对溶解性有机质对有机污染物生物有效性研究进展进行了总结。

Dissolved organic matter(DOM)is an important part of water environment.Due to its special physical and chemical structure,DOM can often influence the environmental behavior of pollutants.Organic pollutants are a kind of pollutants widely existing in the water environment,and have strong biotoxicity,easy to accumulate through the food chain,and pose a threat to the ecosystem and human health.In this paper,the research progress of the bioavailability of dissolved organic matter to organic pollutants is summarized.
