ABSTRACT- Studies from Europe have reported the widespread occurrence of polycyclic musks, 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran (HHCB) and 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronapthalene (AHTN) in wastewater influent and effluent, as well as surface waters. In recent studies the metabolite of HHCB, HHCB-lactone, was detected in wastewater and surface waters. The major sources for HHCB and AHTN to wastewater are thought to be from consumer products such as shampoos, deodorants, laundry detergents, and surface cleaners. As a consequence of putting HHCB and AHTN in many consumer products is that users are constantly exposed to these compounds and these compounds have been shown to bioaccumulate in fish and other aquatic organisms. In this study, we measured concentrations of HHCB, AHTN, and HHCB-lactone from a variety of consumer products. Concentrations ranged from <5 ng/g to over 2000 g/g, <5 ng/g to 400 g/g, and <5 ng/g to 100 g/g, for HHCB, AHTN, and HHCB-lactone, respectively. Highest concentrations were found in deodorants and perfumes. The results suggest a variety of consumer items that are sources of exposure to these compounds, which include many products used on a daily basis.
Key words: Synthetic musk, AHTN, HHCB
