Overview

Heavy metal pollution in Indian waters endangers marine life and sustainable development

Key Facts

  1. Mercury, lead, cadmium and arsenic are the primary heavy metals contaminating Indian rivers and coastal waters.
  2. MoEFCC's 2023 assessment found that ~30% of monitored rivers exceed WHO limits for mercury (0.001 mg/L) and lead (0.01 mg/L).
  3. Bioaccumulation in plankton leads to biomagnification up the food chain, causing neurological disorders in fish and health risks for humans consuming seafood.
  4. The Water (Prevention and Control of Pollution) Act, 1974 empowers the NGT to enforce strict effluent standards for heavy‑metal discharge.
  5. National Water Quality Monitoring Programme (NWQMP), launched in 2017, tracks heavy‑metal concentrations at 1,500 stations across the country.
  6. Heavy‑metal induced loss of marine biodiversity threatens fisheries valued at over ₹1.5 lakh crore annually.
  7. International conventions such as the Minamata Convention on Mercury (adopted by India in 2016) mandate phase‑out of mercury use and enhanced monitoring.

Background & Context

Heavy‑metal contamination falls under GS‑3’s environment and biodiversity syllabus, linking scientific data to policy frameworks like the Water Act and international treaties.
