Water Contamination in India





Disease













Metals



Industrial processes pollute surface waters with metals like lead, arsenic, copper, cadmium, mercury and nickel. These processes include;

  • Mining
  • Discharge of industrial effluents containing metallic solutions into the water. These include effluents discharged from battery and paint manufacturing, electroplating, viscous-rayon manufacturing, copper picking and galvanizing & rubber processing industries.
  • Dumping of solid wastes which contain metal salts
  • Agricultural runoff
Exposure to these metals can cause:


  • Acute or chronic toxicity/poisoning resulting in damaged or reduced mental and central nervous functions
  • Changes in the blood composition and damage to the lungs, kidneys, liver, and other vital organs
  • Physical, muscular, and neurological degenerative processes that are similar to Alzheimer’s disease, Parkinson’s disease, muscular dystrophy, and multiple sclerosis
  • Cancer
  • Risk of allergies
