Volunteer Mercury in Fish Sampling Program

What does Mercury do?

Photo-Fish SamplingEven in small amounts, mercury can have severe effects. The element can damage a brain starting to form or grow, which means that pregnant or nursing women and young children should be especially careful with the consumption of fish. Too much mercury at a young age may affect children's behavior and how well they learn, think and problem solve later in life.

Older children and adults are not exempt from the effects of mercury, however, in order to cause problems, larger amounts of mercury are required. Too much mercury in older children and adults can cause tingling, prickling, numbness in hands and feet, or changes in vision, and even death.
