OCCUBEENCE OF PESTICIDES IN WHALES 



(By Allen A. Wolman^ and Alfred J. Wilson. Jr.=) 



ABSTRACT 



{Organochlorine pesticides were fo^md in tissue samples of brain, flutter, and 

 liver fram 6 of 23 gray whales. Eschrichtius robustus, and in each of 6 sperm 

 whales, Physeter catodon, collected near San Francisco, Calif., in 1968 and 1969. 

 Concentrations of DDT or its metabolites ranged up to 0.36 ppm in blubber 

 tisxue of nrny whales, and 6.0 ppm in blubber tis'^ue of sperm whales. The 

 highest dieldriti concentrations were 0.075 ppm in gray and 0.019 ppm in sperm 

 whales.) 



Residues of the chlorinated hydrocarbon in.secticides, DDT and dieldrin, have 

 been foiuid in various forms of wildlife, mainly in fatty tissues (5, 7) ; these
