Abstract
Aquatic systems are contaminated with chemicals used in soap, lotion, toothpaste and other personal care products at measurable concentrations due, in part, to their high rates of use and persistence during wastewater treatment. Synthetic musk fragrances are used to provide many of these products with a pleasant scent. HHCB (Galaxolide), AHTN, (Tonalide), ATII (Traseolide), ADBI (Celestolide), AHMI (Phantolide), musk ketone and musk xylene are synthetic musk fragrances commonly detected in aquatic systems. The chlorinated compounds triclosan and triclocarban are added to personal care products for their disinfecting properties. These antimicrobial compounds, and methyl triclosan, a degradation product of triclosan are also commonly detected in aquatic systems. The loadings of the synthetic musk fragrances to Lake Erie and Lake Ontario have been assessed by the analysis of sediment cores from these lakes. The HHCB concentrations in the Lake Erie core increased from similar to 1 ng/g in 1980 to similar to 4 ng/g in 2003. A similar trend was observed for AHTN in this core with an increase from similar to 0.2 ng/g to similar to 0.8 ng/g over the same time. The HHCB and AHTN concentrations in similar to 1999 in the Lake Ontario core were 20 ng/g and 1.4 ng/g. Processing of these cores for similar analyses for triclosan, methyl triclosan, and triclcarban are ongoing.
