Sediment-Contaminant Database

Sampling Purpose: This study was designed through the Biology Department of St. Mary's College. The study objectives were (1) to obtain baseline information on total Cd, Cr, Cu, and Zn concentrations in four species of aquatic macrophytes and associated bed sediments from a large backwater area of the Upper Mississippi River (Pool 5A), (2) to characterize the sediment metal levels, and (3) to elucidate the potential impact of aquatic angiosperms in mobilizing sediment-bound metals. Sediment grab samples were analyzed for volatile matter content, particle size, and metals (Cd, Cr, Cu, and Zn). Sample coordinates were not provided with this study; however, coordinates were approximated in ArcView using detailed maps and descriptions of sampling sites.
