Assessment of Missouri River Habitat Quality with Semipermeable Membrane Devices (SPMDs).

摘要

The semipermeable membrane device (SPMD) technology was used to define the presence of organic contaminants in the main stem of the Missouri River. Specifically, the SPMDs were deployed at five sites - Sioux City, IA; Nebraska City, NE; Kansas City, MO; Glasgow, MO; and Hermann, MO - for a period of 28 days. The SPMDs and associated containment cages were prepared at National Fisheries Contaminant Research Center (NFCRC). Following retrieval of the SPMDs, the devices were processed and the extracts analyzed for organochlorine pesticide, polyaromatic hydrocarbon, and polychlorinated biphenyl residues. Over 400 analyses were performed on samples from the five deployment sites.
