Abstract
Two sediment cores collected from Lake Ontario and Lake Erie were sectioned, dated, and analyzed for five polycyclic musk fragrances and two nitro musk fragrances. The polycyclic musk fragrances were HHCB (Galaxolide), AHTN, (Tonalide), ATII (Traseolide), ADBI (Celestolide), and AHMI (Phantolide). The nitro musk fragrances were musk ketone and musk xylene. The chemical signals observed at the two sampling locations were different from each other due primarily to larges differences in the sedimentation rates at the two sampling locations. The sedimentation rates, determined from Pb-210 activity, were 0.73 g/cm2-yr at the site in eastern Lake Erie and 0.027 g/cm2-yr at the site in western Lake Ontario. Each section spanned about 0.5 yr in the Lake Erie core and about 10 yr in the Lake Ontario core. HHCB and AHTN were detected in the Lake Erie core while all seven synthetic musk fragrances were detected in the Lake Ontario core. 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.
