Levels of contaminants including polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), non-ortho-substituted and mono-ortho-substituted dioxinlike polychlorinated biphenyls (DLPCBs) were determined in sediments and freshwater mussels (Dreissena spp. and Elliptio complanata) at three sites in the lower Great Lakes (North America). Impacts of mussel colonization on sediment quality were investigated by comparing contaminant levels in colonized sediment with levels in sediment in the same area that was not colonized, but exposed to similar environmental conditions. Significant impacts on contaminant levels of colonized sediment, compared to noncolonized sediment, were observed at two sites exhibiting high mussel population densities (Fort Erie, eastern Lake Erie, ON, Canada, 2.2 kg/m2 dry wt biomass, and Port Dalhousie, western Lake Ontario, Ontario, Canada, 6.1 kg/m2 dry wt biomass); these differences were not observed at a site with lower mussel densities (Bay of Quinte, eastern Lake Ontario, Ontario, Canada, 0.7 kg/m2). Total organic carbon and contaminant concentrations were statistically significantly greater in colonized sediment, compared to noncolonized sediment, at the two impacted sites. Areal estimates of PCDD/PCDF and DLPCB toxicity equivalents (TEQs) in mussel biomass at the three sites averaged 0.16% and 3.3%, respectively, of the TEQs in the top 3 cm of sediment, indicating that the sediments were the primary sink for contaminants. The observed differences between colonized and noncolonized sediment suggest that Dreissena are capable of influencing the chemical properties of sediment they colonize.

We compared contaminants in zebra and quagga mussels (Dreissena polymorpha and Dreissena bugensis) of two different size classes from sites within the Niagara River to determine if the two species and two size classes can be used to monitor contaminants. Composite samples (i.e., at least 50 individuals) were analysed for 7 trace metals, total PCBs, selected organochlorine pesticides, chlorinated benzenes, and dioxins and furans. ANOVAs and MANOVAs showed that metal tissue concentrations varied significantly among sites, species, and size classes (P < 0.05). At sites where metal concentrations differed between species, zebra mussels had higher concentrations than quagga mussels. Similarly, larger mussels (i.e., 16-25 mm) generally had higher tissue concentrations than smaller mussels (<15 mm length). However, differences in tissue concentrations between size classes were present only for Cd, Cu and Mn and were infrequent, making these results inconclusive. For organic contaminants ANCOVAs and MANCOVAs using lipid concentration as a covariate revealed significant differences in tissue concentrations between the three sites, whereas differences between size classes were modest (P = 0.035). The ANOVA using individual parameters did not show a significant difference in tissue concentrations between the two size classes. In general, mussel tissue concentrations among stations (up to 7 stations throughout the river), were similar for Pb, Zn, Hg and Ni using data separated by species and size class. Concentrations of Cu, Mn and Cd were variable throughout the upper and lower Niagara. Tissue concentrations of α-BHC, 1,2,3 and 1,2,4 trichlorobenzene were similar in quagga mussels collected from 8 stations from the Canadian and American side of the river, whereas concentrations of total PCBs, octachlorostyrene, 1,2,3,4-tetrachlorobenzene, pentachlorobenzene and hexachlorobenzene were higher in quagga mussels from the American side of the upper river.
