Environmental Pollution,Health Risks,and Regulatory Status of Perflu-oroalkyl and Polyfluoroalkyl Substances(PFASs)in China
Per-and polyfluoroalkyl substances(PFASs)are a class of widely used chemicals known for their excellent properties such as water-,oil-,and stain-resistance.PFASs exhibit extreme persistence and stability in the environment,posing a severe threat to ecological balance and human health.Although China is the world's largest producer and consumer of fluorinated compounds,the concentration of PFASs in its environmental media is not higher than that in Europe and the United States.However,the exposure levels of PFASs in Chinese residents are higher than those in the United States,posing health threats to the human immune,metabolic,reproductive,and cardiovascular systems,and affecting fetal development through the reproductive system.Developed countries such as those in Europe and the United States began to address PFASs twenty years ago and have gradually introduced a series of regulatory measures,including setting recommended limits for PFASs in drinking water.China has started to focus on this issue later,and its regulatory measures need improvement.This paper summarizes the regulatory policies in major developed countries and regions,including Europe,the United States,and Japan,to provide references for relevant authorities in China to formulate regulations.
