Mercury and Fish

Earth Gauge Video is available for this tip.

Are you going fishing this season? Many people head to local lakes and streams during nice weather.  A new, four-year, multi-agency study shows a nearly 50 percent chance that the fish you catch will contain mercury. Some levels are so high that pregnant women and children should not eat the fish. Mercury is emitted into the air by power plants, garbage incinerators, even cars. When it falls back to the Earth with rain and snow, it can enter lakes, streams and the fish food chain.

Viewer Tip: If you eat the fish you catch in local waters, check local advisories for advice about consuming fish safely.  Visit www.epa.gov/waterscience/fish to find fish advisories in your area.

Seasons: Spring, Summer, Fall
