Lead is the heavy metal pollutant released by the vehicular exhausts in the air. It precipitates with the rains and mixes with the drinking source of water. It is also directly released by the industries/factories that dump their untreated effluents directly into the water bodies like rivers and ponds. Lead is known to be a severe neurotoxin causing degeneration of the neuronal tissues.

A. Mercury poisoning causes Minamata disease.

B. Calcium excess causes brittle bones.

C. Manganese causes Parkinson's disease.
