Description:
The Environmental Sciences Division (ESD) is investigating the possibility that pharmaceuticals and their metabolites are entering rivers and lakes via sewage treatment effluent. A recent review indicated that some of these compounds are present and have been found in rivers. Compounds developed to induce physiological responses in animals could be endocrine disruptors or have other effects on the biota of the receiving waters. Identification of previously undetected compounds is necessary before their aquatic effects can be evaluated. The ESD hopes to identify any such compounds that might be entering Lake Mead (Las Vegas metropolitan area) in treated sewage discharge.
