Differential accumulation of selenium among axial muscle, reproductive and liver tissues of four warmwater fish species

Journal Article · · Water Resour. Bull.; (United States)
;

Bluegill (Lepomis macrochirus), largemouth bass (Micropterus salmoides), white catfish (Ictalurus catus), and channel catfish (Ictalurus punctatus), collected from an electric power plant cooling reservoir and a municipal water supply reservoir near Roxboro, North Carolina, were analyzed for selenium concentrations in axial muscle, reproductive and liver tissues. Fishes from the municipal water reservoir had lower selenium concentrations (<0.2-2.1 ..mu..g/g - wet weight) than found in the cooling reservoir fishes (1.6-70.0 ..mu..g/g - wet weight) but similar distributions of concentrations among the tissues was evident. Selenium was differentially accumulated, with higher concentrations in liver tissues (0.7 - 70.0 ..mu..g/g - wet weight), followed by female productive tissues (0.7 - 25.0 ..mu..g/g - wet weight), axial muscle tissues (< 0.2 - 23.0 ..mu..g/g - wet weight) and male reproductive tissues (0.02 - 7.2 ..mu..g/g - wet weight).
