Part I of this project has established that fossil hydrocarbons can be distinguished from biogenic hydrocarbons in living organisms. Hydrocarbons are stable in marine organisms and sediments and can move unaltered through several trophic levels. Only very low levels of organic stimuli are necessary for chemical communication--a mechanism especially prone to interference by pollutants. Part II has established that a low level of crude oil (0.9 milliliters/liter) interferes with the timing of feeding behavior in the lobster (Homarus americanus). Water soluble fractions (in the 50 ppb range) did not affect feeding behavior. Added oil reduced the lipids as well as alkane and alkene-aromatic content of aquaria. Degradation of added oil followed the usual pathways of evaporation, dissolution, oxidation, polymerization, and metabolism. (Modified author abstract)
