Avoid the Mercury
The New York City Health Department recently analyzed blood samples for mercury and other heavy metals and found significantly higher levels in people who ate more fish. Levels were also notably higher among wealthy New Yorkers, presumably those who eat more expensive fish such as that found in sushi.
A non-profit environmental group known as the Turtle Island Restoration Network, also analyzed samples of tuna purchased from New York City sushi restaurants, finding nearly half of the 13 samples analyzed contained levels of mercury that exceeded the levels that the FDA considers safe for some women and young children. Some samples even exceeded 1.0 ppm, the level that FDA considers unsafe for human consumption.
Mercury has been used in a wide range of products including dental fillings, electrical switches, thermometers and batteries. Mining metals and the burning of fossil fuels, primarily coal, are among the greatest causes of mercury releases in the environment. Disposal of mercury-bearing consumer products also releases a substantial amount of mercury. While there’s little that can be done to clear the oceans and fish stocks of mercury that’s already out there, cutting back on energy consumption, finding alternative energy sources, and getting mercury out of consumer products are all important ways to help keep the problem from getting much worse.
