- A recent study by IIT Madras reveals the pervasive presence of ‘forever chemicals’ — pre- and polyfluoroalkyl substances (PFAS) — in Buckingham Canal, Adyar River and Chembarambakkam Lake.
- PFAS are a vast family of synthetic chemicals found in everyday products such as non-stick cookware, upholstery, food packaging, water or stain resistant coatings, and industrial materials.
- These chemicals do not degrade easily in the environment.
- These PFAS concentration in the city waters is about 19,400 times more of these ‘forever chemicals’ than the American Environmental Protection Agency’s (EPA) safety levels.
