Why Is This Important?

People may be exposed to mercury from a variety of sources, including drinking water. Mercury, carried by wind and rain, is found throughout the environment mostly due to the release of naturally occurring mercury from rock and soil; burning of coal and oil that contains small amounts of mercury; release of mercury from metal smelters; and incineration of materials that contain mercury, such as batteries. Too much mercury in the human body can cause serious damage to the brain, nervous system and kidneys. Young children and developing fetuses are at greatest risk for harmful effects of mercury.
