Biological effects of mercury-contaminated sediment in northern Thunder Bay, Lake Superior / D. Milani and L.C. Grapentine. : En13-5/05-326E-PDF

"There are elevated levels of mercury in sediments of northern Thunder Bay (inner harbour), Lake Superior. To assess impacts on invertebrate communities, sediment toxicity, and the bioavailability of this mercury and its potential for effects on fish and wildlife through biomagnification, a study was conducted involving (a) comparisons of benthic invertebrate communities and laboratory toxicological response to those established for Great Lakes reference sites, (b) comparisons of total and methyl mercury concentration in sediment and resident benthic invertebrates from Thunder Bay to those from Lake Superior reference sites, (c) analyses of the relationships of total and methyl mercury concentrations in invertebrates to those in sediment, and (d) predictions of methyl mercury concentrations in representative consumers of benthic invertebrates and their predators using screening-level trophic transfer models"--Abstract, page i.
