V. 1. Accounts by locations and species. -- v. 2. Accounts by chemical. During 1970-1988, Canadian Wildlife Service (Ontario) collected eggs from fish-eating colonial waterbirds from 67 colonies throughout the Great Lakes to measure the levels of chlorinated hydrocarbons, metals, and lipid concentrations present. These data were generated as part of a monitoring program started in 1970 to understand the temporal and spatial trends in environmental contaminant levels in biota of the Great Lakes. During 1970-1988, the levels of chlorinated hydrocarbons in colonial waterbird eggs have dropped significantly within colonies across the Great Lakes. "This atlas provides a summary of the mean concentrations of thirty-nine contaminants and the percent lipid measured in eggs of seven species of fish-eating colonial birds sampled only by the Canadian Wildlife Service throughout the Great Lakes during 1970-1988. There are 4491 data points presented in the atlas; however, this does not include any contaminant data concerning biota in the Great Lakes collected by other organizations and agencies"--Introd., p. 12.
