长江流域全氟化合物污染现状及环境基准探讨

Preliminary Discussion on the Pollution Status and Environmental Standards of Perfluorinated Compounds in the Yangtze River Basin

全氟化合物(PFCs)作为一类典型持久性有机污染物,在环境介质中分布广泛且对生态系统和人类健康造成不同程度的危害,因此掌握PFCs在特定区域环境中的分布规律,对制定适应中国的标准限值具有重要的现实意义。长江流域是中国长江经济带的重要组成部分,长江经济带是中国经济社会发展的重点区域,保护长江流域的生态环境对长江流域的绿色发展至关重要。该文聚焦PFCs在长江流域环境中的赋存情况,总结其在上、中、下游水环境、沉积物中的分布及变化规律。在分析长江流域PFCs污染现状与环境基准研究进展的基础上,结合中国对制定PFCs环境基准的研究需求,对今后中国环境中的PFCs环境基准的系统研究提出建议,为PFCs的潜在生态风险评价及控制提供决策依据和参考。

Perfluorinated compounds(PFCs),as a kind of typical persistent organic pollutants,are widely distributed in environmental media and cause varying degrees of harm to ecosystems and human health.Therefore,it is of great practical significance to understand the distribution law of PFCs in the environment of a specific area,and formulate standard limits suitable for China.The Yangtze River Basin is an important part of China’s Yangtze River Economic Belt.It is a key area of Chinese economic and social development.To protect the ecological environment of the Yangtze River Basin is considerable critical for the green development of the Yangtze River Basin.This paper focuses on the existence condition of PFCs in the Yangtze River Basin,and summarizes their distribution and change rule in the upper,middle and lower water environment and sediments.In this paper,the pollution status of PFCs in the Yangtze River Basin and the progress of environmental benchmark research were analyzed,then the research demands of the formulation of environmental benchmarks for PFCs in Chana were clarified.Finally,this article puts forward suggestions for the future systematic research of Chinese PFCs environmental benchmarks and provides decision-making basis and reference for the potential ecological risk assessment and control of PFCs.
