Longitudinal distribution of trace elements (As, Cd, Cr, Hg, Pb, and Se) in fishes and sediment in the Upper Mississippi River:
Sampling Purpose: In 1981, the U.S. Fish and Wildlife Service collected sediment samples to evaluate the longitudinal distribution of six potentially toxic elements in fishes and bed sediments in a 500-km stretch of the Upper Mississippi River (headwaters and Pools 1-10). Forty sediment grab samples were analyzed for volatile matter, particle size, metals, and polychlorinated biphenyls. Sample coordinate information was not provided with this study; however, coordinates were approximated in ArcView using detailed maps provided in the report.
