Occurrence of DDT Residues in Beluga Whales (Delphinapterus leucas) from the Mackenzie Delta, N.W.T.

Publication: Journal of the Fisheries Board of Canada
November 1973

Abstract

Tissues of Beluga whales (Delphinapterus leucas) sampled from a transient herd off the Mackenzie Delta, N.W.T., contained residues of the DDT pesticide group. Muscle and liver contained p,p′-DDE and p,p′-DDT; total residue concentrations in these tissues were approximately 0.01 and 0.02 ppm fresh weight, respectively. Blubber contained p,p′-DDE, p,p′-DDT, and o,p′-DDT; total residue content was approximately 2–4 ppm fresh weight.

Résumé

Des tissus de béluga (Delphinapterus leucas) prélevés à même un troupeau de passage au large du delta du Mackenzie, T.N.-O., contenaient des résidus des pesticides du groupe DDT. Le muscle et le foie contenaient p,p′-DDE et p,p′-DDT; la concentration totale des résidus dans ces tissus était approximativement 0.01 et 0.02 ppm de poids frais respectivement. La graisse contenait p,p′-DDE, p,p′-DDT et o,p′-DDT; le contenu en résidus totaux était d’environ 2–4 ppm de poids frais.
