| Abstract: | Abstract: This document reports the results of a biomonitoring study applied to quantify the role of the aquatic portion of the Times Beach confined disposal facility (CDF) at Buffalo, NY, as a potential source of contaminants for Lake Erie and the Niagara River. Mussels (Elliptio dilatata) were collected from a pristine lake and exposed as biomonitors in the Buffalo River, Lake Erie, and Times Beach. After 35 days exposure, the mussels were recovered and analyzed for polychlorinated biphenyls (PCBs), hexachlorobenzene, and pesticides (op-DDE and pp-DDE). The PCBs and pesticides were found to be present in the Buffalo River, Lake Erie, and the CDF. The biomonitor mussels placed inside the CDF accumulated PCB congeners 28, 44, 49, 52, 70, 87, and 101 to levels significantly higher than those of the mussels placed outside the dike. Concentrations of PCBs 138 and 153 were significantly higher in the biomonitors placed outside the dike. The pesticide concentrations in the biomonitor mussels were significantly higher in the CDF than in either the Buffalo River or Lake Erie. |
