Per- and Polyfluoroalkyl Substances (PFAs), known as ‘Forever Chemicals,’ have been detected in Buckingham Canal, Adyar River, and Chembarambakkam Lake by IIT Madras.
About Per- and Polyfluoroalkyl Substances (PFAs):
- Also known as ‘Forever Chemicals’, Per- and Polyfluoroalkyl Substances (PFAs) are a vast family of synthetic chemicals that are pervasive in our environment.
- They are found in everyday products like non-stick cookware, water or stain-resistant coatings, and industrial materials.
- Common Uses: Nonstick cookware, water-repellent clothing, stain-resistant fabrics, cosmetics, and firefighting foams.
- They help products resist grease, water, and oil.
Environmental and Health Concerns:
- Persistence in Nature: PFAS do not easily break down, leading to long-term environmental presence.
- Bioaccumulation: Accumulate in living organisms, increasing exposure and potential harm over time.
- Health Risks: Linked to liver damage, hormonal imbalances, fertility issues, and increased cancer risk.
- Immune System Impact: May impair antibody formation after vaccinations.
