The Bhopal Gas tragedy is the worst air pollution episode ever witnessed in India. It happened in Bhopal on December 3, 1984.

The Union Carbide factory is located in Bhopal, a town in Madhya Pradesh. The fateful incident happened due to the leakage of lethal gas called methyl isocyanate (MIC) gas from three storage tanks of Union Carbide factory, a Multinational Corporation. MIC is an intermediate used in the manufacture of pesticides. Methyl isocyanate (MIC) is produced by combination of phosgene, a deadly poisonous gas used in the First World War with methyl amine. In the accident nearly 36 tones of poisonous MIC gas released into the air of Bhopal. MIC gas causes burning sensation in the eyes, removes oxygen from the lungs resulting in breathing trouble and chest tightness, and also cyanide generation in the body, which ultimately turn fatal and leads to death.
