the observed effects on behavior may be due to oil-induced changes in 
chemoreception. At higher exposure levels (1 ppm range), the behavioral 
effects appear neuromuscular, with a loss of coordination and equilibrium. 
These preliminary results are being corroborated at different exposure levels. 
In additional experiments, we will attempt to provide a correlation between 
behavioral and neurophysiological results of oil exposure to determine if the 
observed behavioral effects of oil are caused by a malfunctioning 
chemoreceptor system. 
ACKNOWLEDGEMENT 
We would like to thank L. Ashkenas, B. Bryant and T. Dourdeville for 
expert technical assistance. We are indebted to B. Melzian and D. Stenzler for 
help in designing and construction of the flow-through oil dosing system. Dr. 
B. Ache and B. Johnson provided us with the design and training for valuable 
discussions during the course of these experiments. Financial support was 
provided by grants from the U.S. Environmental Protection Agency 
(R-803833) and the U.S. Energy Research and Development Administration 
(E(l 1-1)2546).
