The uptake of PAC (PAH and PASH) into the muscle of feral and laboratory exposed flatfish is described and modeled using the fugacity approach. Correlation is made between the results obtained from the exposure of winter flounder to a crude oil and the analysis of samples obtained from feral finfish. The feral study involved the collection of American plaice and yellowtail flounder from the Northwest Atlantic during biological surveys. Finfish were pooled according to species, sex, size, season and sampling location. Muscle, liver and gall bladder bile were examined for the presence of saturated and unsaturated hydrocarbons or metabolites. On the other hand after a four month exposure to a crude oil, muscle of winter flounder was analyzed for saturated hydrocarbons and polycyclic aromatic compounds, as well as the gall bladder for bile metabolites. The information obtained in the laboratory experiment allowed a better interpretation of the results observed in the fish sampled from the Northwest Atlantic. The assessment of the fate of hydrocarbons in biota is discussed taking into consideration variables such as: animal size, respiration rate, lipid content of tissue, TOC, K{sub ow} of chemicals and the knowledge of the source and fingerprint of PAH in the Northwest Atlantic environment.
