Levels of synthetic musk compounds in municipal wastewater for potential estimation of biota exposure in receiving waters

摘要

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 7-12 months.The lipid content of each fish was determined and compared with the concentration of musks in the whole fish tissue.Enhanced 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 polycyclic and nitro musk compounds in sewage effluent,Lake Mead water,and carp.The concentrations were found to be considerably lower than previous studies conducted in other countries.This study also provides data for polycyclic and nitro musk compounds,as well as some of the nitro musk metabolites in sewage treatment plant effluent,lake water,and carp.
