Abstract

Tensas River National Wildlife Refuge, Madison Parish, Louisiana, consists of bottomland hardwood swamps interspersed with small lakes and bayous supporting a diverse assemblage of waterfowl, fish, and assorted species of game and nongame wildlife. Fish collected in the refuge in 1984–85 from areas receiving direct inflow from agricultural runoff contained from 5 to 10 μg/g total DDT (primarily DDE) and toxaphene (measured on a whole-body, wet-weight basis). These concentrations in fish, which were still high enough to pose a threat to fish-eating birds and wildlife, demonstrated that residues from past use of DDT and toxaphene in the area were still available for transport and uptake. In future water projects, the incorporation of structures to prevent contaminated runoff from entering the refuge should reduce waterborne contamination to the refuge.
