摘要：

Sediments collected in 2004 from along the Detroit River (n = 19) and across all of Lake Erie (n = 18) were analyzed for isomers of the flame retardant chemical, hexabromocyclododecane (HBCD), using liquid chromatography-tandem mass spectrometry. Sediment samples had I HBCD pound concentrations ranging from not detected to 1.6 ng/g d.w. gamma-HBCD (56 %-100 % of I HBCDs) pound was the predominate isomer, observed in 7 of 19 samples from the Detroit River and 6 of 18 samples from Lake Erie (all within the western basin). alpha-HBCD was found in 4 Detroit River and 2 Lake Erie western basin sites, while beta-HBCD was only in two Detroit River samples. High I HBCD pound concentrations (> 100 ng/g d.w.) were found in two sludge samples from two Windsor, ON, wastewater treatment plants that feed into the Detroit River upstream. HBCD contamination into the Detroit River is a major input vector into Lake Erie and with an apparent sediment dilution effect moving towards the eastern basin.
