Minamata Bay (1 janv. 1950 – 31 déc. 1969)

Description:

In the late 1950s Minimata Bay became contaminated with Mercury from a nearby factory manufacturing the chemical acetaldehyde. Mercury, used in the manufacturing process, was being discharged into the Bay. Due to mercury's bioaccumulative properties, the fish in the bay were being over exposed to methyl mercury. The fish passed on the Mercury built up in their bodies to the fish-consuming residents nearby. Scientists estimate that the Biomagnification of the Mercury was as great as a millionfold (#Dartmouth, 2001).
