The toxic chemical responsible for the 1984 Bhopal disaster was________________?
Show answer Hide answer
Answer: B. Methyl isocyanate (MIC)
Explanation
Methyl isocyanate was stored in large quantities at the Union Carbide pesticide plant in Bhopal. An accidental chemical reaction released this extremely toxic intermediate into the atmosphere. The resulting toxic cloud caused a devastating humanitarian and environmental disaster in 1984. Methyl isocyanate is a volatile organic intermediate used in the production of carbamate pesticides. Exposure to trace amounts causes severe irritation of the eyes, nose, and respiratory tract. Industrial safety standards classify MIC among the most hazardous chemicals ever manufactured.
The Bhopal disaster remains a landmark case study in industrial safety and risk management. Global chemical regulations were drastically tightened following this tragic historical event. Modern facilities handling hazardous intermediates employ redundant containment and neutralization systems. Phosgene is a toxic war gas and chemical intermediate but was not the agent in Bhopal. Carbon monoxide is a common combustion poison rather than the specific pesticide intermediate released. Sulfur dioxide is a typical power plant pollutant rather than the Bhopal disaster agent.
