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

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.
