High levels of toxic mercury have been found in walleye caught in the Western N.C. lakes of Santeetlah and Fontana, prompting a state health warning.
Mercury occurs naturally but is released into the environment by burning coal, such as in power plants. When it falls into water, it can accumulate in fish. Eating high-mercury fish over time can pose health risks, especially for children and developing fetuses.
