Chisso
The Chisso Corporation (チッソ株式会社, Chisso kabushiki kaisha), since 2012 reorganized as JNC (Japan New Chisso), is a . It is an important supplier of liquid crystal used for LCDs, but is best known for its role in the 34-year-long pollution of the water supply in Minamata, Japan, which caused Minamata disease—a devastating neurological condition that has led to thousands of victims of the disease dying, becoming disabled or exhibiting signs of mercury poisoning.
Between 1932 and 1968, Chisso's chemical factory in Minamata released large quantities of industrial wastewater that was contaminated with highly toxicmethylmercury. This poisonous water bioaccumulated in local sea life that was then consumed by the immediate population. As a result of this contamination, 2,265 individuals in the area were afflicted with what is now known as Minamata disease. 1,784 of those victims died as a result of the poisoning and/or the disease. Those who were afflicted with the disease developed skeletomuscular deformities and lost the ability to perform motor functions such as walking. Many also lost significant amounts of vision, as well as hearing and speech capabilities. Severe cases presented with insanity, paralysis, coma and then death within weeks of the onset of symptoms.
As of March 2001, over 10,000 individuals had received financial remuneration from Chisso to compensate them for the harm caused by the chemical release. By 2004, Chisso Corporation had paid $86 million in compensation, and, in the same year, the company was ordered to clean up its contamination. However, the incident remains controversial for not only the poisoning itself but also for the tactics that the company used to suppress the negative aftermath.
