On December 3rd 1984, a Union Carbide pesticides plant released a toxic gas which resulted in the deaths of thousands of people and the permanent injury of thousands more. 25 years on, the effects are still being felt in the region.
'A total of 36 wards were marked by the authorities as being "gas affected", affecting a population of 520,000. Of these, 200,000 were below 15 years of age, and 3,000 were pregnant women. In 1991, 3,928 deaths had been certified. Independent organizations recorded 8,000 dead in the first days. Other estimations vary between 10,000 and 30,000. Another 100,000 to 200,000 people are estimated to have permanent injuries of different degrees.
In 2009, a day before the 25th anniversary of the disaster, Centre for Science and Environment (CSE), a Delhi based pollution monitoring lab, released latest tests from a study showing that groundwater in areas even three km from the factory up to 38.6 times more pesticides than Indian standards.
The BBC took a water sample from a frequently used hand pump, located just north of the plant. The sample, tested in UK, was found to contain 1000 times the World Health Organization's recommended maximum amount of carbon tetrachloride, a carcinogenic toxin. This shows that the ground water has been contaminated due to toxins leaking from the factory site.'
Union Carbide is now a wholly owned subsidiary of The Dow Chemical Company.
Dow AgroSciences produces insecticides, herbicides, fumigants, fungicides for the agricultural industry and for home and garden use.
