How the coal industry poisoned your tuna sandwich #mercury

Inorganic mercury isn't easily assimilated into the human body, and if the mercury emitted by power plants stayed in that form, it probably wouldn't have made Gelfond and many others sick. But when inorganic mercury creeps into aquatic sediments and marshes (as well as mid-depths of oceans), bacteria convert it into methylmercury, an organic form that not only is easily assimilated but also accumulates in living tissue as it moves up the food chain: The bigger and older the fish, the more mercury in its meat. It takes only a tiny amount to do serious damage: One-seventieth of a teaspoon can pollute a 20-acre lake to the point where its fish are unsafe to eat. Thousands of tons a year settle in the world's oceans, where they bioaccumulate in carnivorous fish. Forty percent of human mercury exposure comes from a single source--Pacific tuna.
