Cadmium, metal-binding proteins, and growth in bluegill (Lepomis macrochirus) exposed to contaminated sediments from the Upper Mississippi River Basin:
Sampling Purpose: This study was designed through Iowa State University to assess the responses of bluegills to cadmium-contaminated, surficial sediments from five sites on the Upper Mississippi, Illinois, and Des Plaines rivers. The chief objectives were (1) to assess the bioaccumulation of cadmium in fish exposed to suspended river sediments and (2) to evaluate whole-body cadmium, hepatic metal-binding proteins, and hepatic nonthionein cytosolic cadmium in bluegills as indicators of exposure to sediment-associated cadmium. Sediment grab samples were collected in June 1990 for use in bioassays and were analyzed for volatile matter, particle size, water content, and metals.
