Mercury levels elevated in fish
Health advisories are in effect for waterways in eastern Virginia

Fish are contaminated with mercury in three swampy waterways in eastern Virginia, and no one quite knows why.

The DEQ will form a committee of health experts, scientists and citizens to investigate the pollution.


Potential sources of the mercury include air pollution and pesticides, Hayden said. Or the mercury could have formed naturally in the swampy soils.

Coal-fired power plants are major sources of airborne mercury, but Hayden said there are not any plants near the tainted waters.

Some scientists believe swamps' acidic waters create conditions that help mercury accumulate in fish.

Earlier tests found high levels of PCBs in fish below Smith Mountain Lake; an advisory was already in effect there.
