Organic Fluorine Compounds Detected in Sludge from 34 Japanese Wastewater Treatment Plants

Researchers from Kyoto University selected 34 wastewater treatment plants from approximately 2,200 nationwide for testing and analysis. Results revealed that sludge from all 34 plants contained perfluoroalkyl and polyfluoroalkyl substances (PFAS). These compounds are difficult to degrade, accumulate in the environment and human bodies, and are known as “forever chemicals.”
