Trace-element concentrations in streambed sediment across the conterminous United States

Article Abstract:

The U.S. Geological Survey conducted a study concentrations of trace elements in 541 streambed-sediment sites in 20 sites around the United States as part of its National Water-Quality Assessment Program. Forty-nine percent of the sites sampled had trace elements (copper, mercury, lead, and zinc) had concentrations high enough to affect stream biota.
