Mercury poisoning, minamata disease, and other mercury caused diseases all have similar symptoms: Rashes, mood swings and memory loss, muscle weakness, mental disturbances, numbness, impairment of peripheral vision, speech, walking, hearing and lack of coordination. However, mercury effects each person differently. The Start of Minamata Disease Minamata Bay Minamata Bay is a small fishing and farming town on the Shirauni Sea. It is on the island of Wakayama on the Kii peninsula. Minamata Bay is notorious for being a "factory town" and it's most famous factory being the Chisso Factory. The spread of minamata disease didn't occur until the early 1900's. Although the symptoms started out subtley, no one knew how much of a problem and health hazard this would turn into. The Chisso factory began running in 1907 and started dumping waste water from their factory in 1925. This is when the effects of Minamata disease became more apparent. Fish began to float to the surface, birds died in midflight and cats "danced" in the streets as if possessed. The company started paying fisherman for the damage they caused. This, to them, was easier and cheaper than cleaning up the mess they made. In 1932, Chisso began creating new products with a new chemical called acetaldehyde. Acetaldehyde is based from mercury compound. Soon enough, people began to act strange. It was subtle in the beginning where people couldn't button their buttons, or they would drop their chopsticks but then the symptoms began to get worse. What was the cause of this neurological disease? It wasn't until the 1950's that people began to associate the illness to the pollutants in the water. In 1956, Dr. Hosokawa (from Chisso Hospital) began associating the food with the contaminated water. The company denied any responsibility for contamination of the water. Chisso switched the dumping spot to Minamata river - the only problem was that the river still flowed into the ocean and was still contaminating the fish. The river flowed by another town, and townsmembers began experiencing the same symptoms as the people in Minamata Bay. The government created a ban from fisherman selling fish, but they could still catch fish. People still ate fish but the government wasn't responsible for the illnesses. In 1959, Dr. Hosokawa began doing experiments to test his hypothesis on the pollutants. He fed cats acetaldehyde and their nervous systems began shutting down. After he showed his experiments to the corporation, he was forbidden to continue with any further experiments and his previous experiments were concealed. The Chisso Corporation started paying effected victimes but the contract said "if Chisso Corporation were later proven guilty, the company would not be liable for later compensation." Fisherman began protesting for compensation and the corporation went to court. The Chisso Corporation had been polluting the water consistently for 36 years. They said they stopped in 1969 but the Japanese government has been covering up the fact that Chisso is still polluting today. is now this. what was once this... healthy brain cells brain cells from a body with mercury poisoning Mercury Poisoning
