Mercury in fish: Hold the sushi

Mercury in fish: Hold the sushi | The Economist: "The new study was conducted by the US Geological Survey (USGS), a scientific agency run by the government. It found traces of methylmercury, a form of mercury that is readily absorbed, in every fish sampled in 291 streams across the country. In around a quarter of those fish, the amount of mercury was above the level set by the Environmental Protection Agency (EPA) as safe for human consumption. Mercury levels at more than two-thirds of the sites exceeded what scientists believe fish-eating mammals, such as mink and otters, should ingest.

The leading source of mercury is pollution from coal-burning power plants, which accounts for 40% of all domestic anthropogenic mercury, according to the EPA."
