Mercury Rising

"All fish should be poison free, says Orli Cotel, deputy communications
director of Sierra Club. Sadly, we know they're not. How do fish become
contaminated in the first place? Coal-fired power plants are the largest
man-made source of mercury emissions in the United States, and once the
neurotoxin enters the water, it's practically impossible to eliminate
from the food chain. The EPA is proposing a nationwide cap on mercury
pollution, and Sierra Club is now offering to test samples of your hair
to reveal how much is in your body. Simply fill out a form at sierraclub.
org/mercury and, for $20, you'll have an answer within weeks. If your
levels are high, rest assured that mercury cycles out of the body within
a few months."
