  • It is widely distributed throughout the environment in the air, water and land.
  • It is highly toxic in its inorganic form.
  • Contaminated water used for drinking, irrigation of food crops and food preparation poses the greatest threat to public health from arsenic
  • Long-term exposure to arsenic from drinking-water and food can lead to chronic arsenic poisoning.
  • It can cause cancer, skin lesions, developmental effects, cardiovascular disease, neurotoxicity and diabetes.
  • The most important action in affected communities is the prevention of further exposure to arsenic by providing them of a safe water supply.
  • It is a high-profile problem in the Ganges Delta, due to the use of deep tubewells for water supply.
  • The groundwater in these tubewells have high concentrations of arsenic in deeper levels.
