The Yangtze River. © pixabay Drinking water for millions of people in China has unsafe levels of PFAS toxics, according to a study released by Tsinghua University earlier this month. The researchers analyzed 526 drinking water samples across 66 Chinese cities for perfluoro- and polyfluoroalkyl substances (PFAS), which are durable, man-made chemicals found in products such as textiles, firefighting foam, and pesticides. The study concluded that just under 100 million people in the examined cities have PFAS concentrations in their drinking water above safe levels. Since China does not have any national safety standards for PFAS, the researchers used the maximum PFAS limit set by Vermont in 2019. This is the first study on PFAS contamination and associated health conditions completed in China.
