Contaminants measured in multiple environmental media in the Lake Mead National Recreation Area NV/AZ, USA in 2010
December 12, 2024
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.

Fish health altered by contaminants and low water temperatures compounded by prolonged regional drought in the Lower Colorado River Basin, USA
The goal of this study was to assess health of male Common Carp (carp, Cyprinus carpio) at four sites with a wide range in environmental organic contaminant (EOC) concentrations and water temperatures in Lake Mead National Recreation Area NV/AZ, US, and the potential influence of regional drought. Histological and reproductive biomarkers were measured in 17–30 carp at four sites and 130...
