Solution
The correct option is A Minamata
The toxic substances pass from one trophic level to the other trophic level, their increasing accumulation leads to a greater harm at higher trophic level. In the late 1950's Minamata 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 methylmercury. 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 millionfold. Thus, the correct answer is option A.
