Arsenic (As3+, As5+>12 μg/L

Contaminated ground water is a source of inorganic arsenic (As2O3), dietary sources contain organic arsenic which includes fish, shellfish, meat, poultry, dairy products and cereals.

Inorganic arsenic is a potent carcinogen. Acute arsenic poisoning includes vomiting, abdominal pain and diarrhoea. Long-term exposure to high levels of inorganic arsenic leads to pigmentation changes, skin lesions and hyperkeratosis. Organic arsenic is less harmful to human health.
