Analyses of organic and inorganic contaminants in Salton Sea fish

摘要

Chemical contamination of fish from the Salton Sea, a quasi-marine lake in Southern California, could adversely impact millions of birds using the Pacific Flyway and thousands of humans using the lake for recreation. Bairdiella icistia (bairdiella), Cynoscion xanthulus (organgemouth corvina), and Oreohromis spp. (tilapia) were sampled from two river mouths and two nearshore areas of the Salton sea. Muscle tissues were analyzed for a complete suite of 14 trace metals and 53 pesticides. Fish muscle tissues had concentrations of selenium ranging between 1.89 and 2.73 μg/g wet weight.
