Contaminants measured in multiple environmental media in the Lake Mead National Recreation Area NV/AZ, USA in 2010

Concentrations of a wide variety of environmental organic contaminants were measured in surface waters of the Lake Mead National Recreation Area (Nevada and Arizona) in 2010 to provide a measure of exposure to resident fish species. These contaminants were sampled using the semipermeable membrane device (SPMD) and the polar organic chemical integrative sampler (POCIS) which allow for the determination of the average contaminant concentrations over a month-long study period. Contaminants measured included polycyclic aromatic hydrocarbons, polychlorinated biphenyls, organochlorine pesticides, pharmaceuticals, select illicit drugs, and other chemicals related to wastewater treatment plant effluents. In addition, sediments, periphyton, fish feeds, and other materials from the Willow Beach fish hatchery were screened for polychlorinated biphenyls which are historically present in many hatcheries across the Nation.
