5203 |a"The results of chemical analyses of raptor eggs and tissues collected by the Canadian Wildlife Service between 1965 and 1988 are summarized. Residue levels are reported for DDE, DDD, DDT, dieldrin, heptachlor epoxide, HCB, PCBs, beta-HCH, oxychlordane, mirex and mercury in twenty-four species of Canadian raptors. Of these, only three tissue samples contain residues (mercury or DDE) indicative of acute poisoning. Critical toxic effect values for DDE, dieldrin, heptachlor epoxide and mercury in eggs are determined from the published literature, and the proportions of sampled eggs with residues in excess of those levels are reported. Contaminant data for eight species are analyzed for temporal trends. Results are discussed with respect to changes in the status of raptor populations in Canada"--Abstract, p. vi.
