Digitized edition from print [produced by Environment and Climate Change Canada] Includes bibliographical references: p. 12. "Shellfish, seabirds and marine mammals are often used as convenient indicators of the amounts of chemical contaminants and pollutants present in their environment. The concentrations of various POPs have been measured periodically in habitats and tissues of several such species in the Gulf of Maine and Bay of Fundy. Shellfish, such as mussels, filter contaminated particles and absorb the chemicals from seawater. Seabirds, seals and porpoises, are long-lived, range over a wide area and feed high on the food chain. They accumulate contaminants from their prey by a process of biomagnification, whereby concentrations of contaminants steadily build up in each successive layer of the food chain. There is reliable information about the general trends in concentrations of many POPs in the Fundy region from the 1960s and early 70s to the present. This is largely attributable to the foresight of Department of Fisheries and Oceans and Environment Canada scientists in establishing longterm shellfish and seabird monitoring programs, and of some university researchers in measuring contaminants in tissues of various marine mammals over many years."--p. 7. gccst Aquatic ecosystems gccst Pollution Canada.
