Description:
Synthetic musk compounds are consumer chemicals manufactured as fragrance materials and consumed in very large quantities worldwide. Due to their high usage and release, they have become ubiquitous in the environment. The U.S. EPA (Las Vegas) developed surface water monitoring methodology and conducted a one-year monthly monitoring of synthetic musk compounds in water and biota from Lake Mead (Nevada) as well as from combined sewage effluent streams feeding Lake Mead. Evaluation of data obtained from the analyses of combined effluent streams from three municipal sewage treatment plants (STPs), from lake water, and from whole carp (Cyprinus carpio) showed a relationship between values from the source (STPs effluent) and those from the receiving waters (Lake Mead). Presented here is the overview of the chemistry, the monitoring methodology, and the statistical evaluation of data obtained from the analysis of a suite of these compounds in three different environmental compartments.
