A guide to the Canadian Wildlife Service National Registry of Toxic Chemical Residues / J.E. Elliott, W.J. Learning, Y. Ouellette. : CW69-5/27E-PDF

"The computerized National Registry of Toxic Chemical Residues is a repository for information on wildlife specimens analyzed for toxic chemicals by the Canadian wildlife Service (CWS), or deposited in the CWS National Specimen Bank. Since 1963, residue data for more than 30, 000 individual specimens representing 327 species of Canadian wildlife have been added to the data base. Specimens were collected mainly from Canadian territories or near boundary U.S. territories, especially in the Great Lakes. There are also limited data from Canadian migratory species and their prey collected in Central and South America. The registry contains data only from specimens collected in the field and not experimentally dosed. This "User Guide" should help interested persons understand the registry system and assist the user in obtaining both data on residue levels in wildlife and information on the contents of the CWS National Specimen Bank"--Abstract, p. iv.
