Levels of Synthetic Musks Compounds in Municipal Wastewater for Estimating Biota Exposure in Receiving Waters

Abstract:Synthetic musk compounds are consumer chemicals manufactured as fragrance materials and consumed in very large quantities worldwide. Due to their high use and release, they have become ubiquitous in the environment. We analyzed water samples from the confluence of three municipal sewage treatment effluent streams, surface water, and whole carp ( Cyprinus carpio) for synthetic musks for a period of 12 months. The lipid content of each fish was determined and compared with the concentration of musks in the whole fish tissue. Innovative methods were used for water sampling and musk extraction. The data presented here provide insight as to the relationship between concentrations of synthetic musks in the municipal effluent and associated biota. This study confirmed the presence of polycylic and nitro musk compounds in sewage effluuent, Lake Mead water, and carp. The concentrations were found to be considerably lower than previous studies conducted in oilier countries. This study also established the statistical variation in the concentrations of Galaxolide (a polycyclic musk) and musk xylene (a nitro musk) in carp.
