This recent bit of fishy news kind of freaks me out:
According to a recent study by the US Geological Survey, every single fish sampled from 291 streams across the United States between 1998-2005 was contaminated with mercury.
A quarter of the sampled fish contained levels of mercury higher than those deemed safe for human consumption and more than two thirds contained levels exceeding the Environmental Protection Agency’s level of concern for the protection of fish-eating mammals.
Most of the mercury comes from coal power plant emissions, where the mercury in the atmosphere gets precipitated down, then converted to methyl mercury, the toxic stuff polluting our waterways.
Now I know I’m a veggie so I don’t need to worry about my own safety, but there’s the planet and the rest of its fish-eating species to worry about – people included. Barbara Scudder, a scientist with the USGS, advises that people should eat more fish species lower down the food chain, such as perch, bluegill or crappie.
Elsewhere, Ward Eldred asks a few interesting questions that I wouldn’t mind knowing the answers to:
The question I want answered is how much mercury was in the streams and fish 30 years ago? 50 years ago? Has it increased? The article says it comes from coal-fired power plants. Oh, and it comes from areas mined for gold and mercury. Does it perhaps just naturally leach from the earth? And has it been doing it for millions of years?
