Q4+Minamata

__**QUESTION 4 ** __  **How did it happen? ** The Minamata disease is a disease that will affect the nervous system. It was caused from eating alot of fish and shellfish that were highly contaminated by methyl mercury daily. It is serious mercury poisoning. Minamata was caused by Chisso Corp. using mercury sulphate as a catalyst in a chemical reaction used to make some of their products which then went into the Minamata Bay along with the waste water. It continued on because no one would do anything to prevent it. ﻿**Who or what caused this disaster?** This chemical disaster was caused by Chisso Corp. dumping the methyl mercury into the Minamata Bay in their waste water. The marine life that lived in the contaminated waters soaked up the mercury through their gills then it soaked into their flesh; when the fishermen caught the fish and when their family ate the fish they slowly began to get Minamata disease. **Why did it happen? ** Minamata happened because Chisso Corp. didn’t know what they were doing or how it had affected humans. When they did find out what methyl mercury could do, they didn’t stop. Chisso Corp. didn’t try to stop it andneither did the government.
