Hi,

Minamata disease is caused by mercury poisoning. It occurred in Japan in 1952 to 1960.

In 1952, a company involved in making plastic products dumped its waste water into the Minamata River. Buy the time they were stopped in 1966, 400 tons of mercury was was dumped.

Minamata disease caused nerve problem and involuntary nervous twitches and loss of balance when walking. Severe birth defects was seen in children born to mothers who consumed tainted fish and other seafood from the region. Even small amounts bio-non degradable substances get concentrated into lethal concentrations due to bioaccumulation.



Cheers
