To stay informed of seafood with problematic levels of mercury women are advised to contact their doctors.

Fish provide important health benefits to the developing fetus, and pregnant women should be encouraged to eat fish with consistently low mercury levels. With too many species, however, these nutritional benefits are outweighed by the hazards of mercury.

If American women ate a varied diet of FDA's recommended 12 ounces of fish a week they would expose more than one fourth of all fetuses to a potentially harmful dose of methyl mercury for at least one month during pregnancy.

That about 10 percent of all women of childbearing age have blood mercury levels above the dose that may put their fetus at risk for adverse neurological effects.

It only takes a fraction of a teaspoon of mercury to contaminate an entire 25-acre lake to the point where fish are unsafe to eat.

Power plants are responsible for 34% of the total mercury emitted by all known sources. Older power plants emit as much as ten times more pollution that modern plants.
