Mercury From Gold Rush Found In Fish In California
Elemental mercury, the kind you can see, is only one part of the problem, it is the presence of methylmercury, the organic form of mercury that accumulates in organisms that will be of most concern.
Government scientists have detected elevated levels of mercury in bass and catfish in the Bear and South Yuba River watersheds in the Sierra Nevada of northern California as part of the first major study of mercury concentrations in the area.
Mercury is a well-known environmental pollutant that can have serious effects on human health.
