Cadmium and mercury in sediment and burrowing mayfly nymphs (Hexagenia) in the Upper Mississippi River, USA:
Sampling Purpose: This study was designed through Iowa State University to examine the relation between cadmium and mercury concentrations in burrowing mayfly nymphs and surrounding sediments in a 572-km reach of the Upper Mississippi River (UMR). Sediment grab samples were collected from Pools 2-7, 9, 12, and 16 on the UMR, and analyzed for volatile matter, particle size, cadmium, and mercury. Field-collected mayfly nymphs were also analyzed for cadmium and mercury.
