"Elevated concentrations of mercury exist in sediments of the Cornwall area of the St. Lawrence River. To assess the bioavailability of this mercury and its potential for effects on fish, wildlife and humans through biomagnification, a study was conducted involving (a) analyses of the relationships of total and methyl mercury concentrations in benthic invertebrates to those in sediment, and (b) predictions of concentrations of total and methyl mercury in representative consumers of benthic invertebrates and their predators using screening- level trophic transfer models"--Abstract, page i. gccst Mercury gccst Sediments gccst Rivers Mackay, Scott, author.
