achieved (Gay and Bel isle, personal communication). Dr. John Laseter (personal 

 communication) has detected petroleum hydrocarbons in the liver, heart, kidney, 

 brain, skin, fat, breast muscle, and uropygial gland of mallard ducks which 

 were dosed with crude oil. 



ACKNOWLEDGMENTS 



Research on the effects of petroleum on aquatic birds is being performed 

 at the Patuxent Wildlife Research Center by seven people in addition to myself: 

 Dr. Michael Dieter, physiologist and leader of the oil research team; Nancy 

 Coon, biologist; Andre Bel isle, chemist; Dr. Martha Gay, chemist; Dr. Jon 

 Patton, physiologist; Dr. Robert Szaro, biologist, and Dr. Barry Tarshis, 

 zoologist. I thank all of them for their assistance in preparing this paper.
