Context: A recent study by IIT Madras has uncovered the presence of ‘forever chemicals’ known as pre- and polyfluoroalkyl substances (PFAS) in Chennai’s Buckingham Canal, Adyar River, and Chembarambakkam Lake.

  • PFAS are synthetic chemicals found in everyday products and are known to persist in the environment, posing health risks including liver damage, hormonal imbalance, fertility issues, and cancer.
  • PFAS are called “forever chemicals” because they do not easily break down in the environment and can persist for long periods of time.
