PFAS widespread in China's tap water, posing risks to children

A national assessment of tap water in China found widespread PFAS contamination, with a national median concentration of 4.75 ng/L and a maximum of 19,952 ng/L in Shanxi.

This study analyzed 119 tap water samples across China to assess the occurrence and health risks of 32 PFAS compounds, finding 15 detected and identifying specific contamination hotspots.

The abstract suggests implementing region-specific source control to mitigate exposure risks.

This was the first national-scale assessment of PFAS in China's tap water, analyzing 119 samples for 32 target compounds. The study used risk quotient analysis and Positive Matrix Factorization to identify sources and assess health risks.
