Abstract

Channel catfish (lctalurus punctatus) were collected at ten locations from the Missouri River adjoining Nebraska. Fillet samples were found to be contaminated with DDT, PCB, dieldrin, heptachlor, trifluralin, and chlordane. At one location, near Bellevue, concentrations of chlordane exceeded Federal Food and Drug Administration action levels. This indicates channel catfish caught and consumed from the Bellevue area may pose a threat to human health. This study provides baseline information on the contamination of channel catfish in the Missouri River adjoining Nebraska.
