Being sessile filter-feeders, clams are readily exposed to pollutants adsorbed on suspended particulate matter. Little is known of the extent to which petroleum hydrocarbons taken up by marine bivalves are retained and concentrated in their tissues. Such assimilation and concentration could pose a health threat to human consumers of edible marine shellfish as some of the polycyclic aromatic hydrocarbons have been reported to be carcinogenic. Aromatic hydrocarbons are more water soluble than paraffinic and naphthenic hydrocarbons with the paraffins reported to be preferentially attached by micro-organisms resulting in an increase in the aromaticity of the residue. Evidence presented indicated that the more highly refined oils are more toxic to the biota than heavier oils, perhaps due to their greater percentage of aromatic hydrocarbons which are known to be toxic to a wide variety of marine organisms. In this study we selected to look at six specific monocyclic aromatics of the water-soluble fraction (WSF) of Cook Inlet crude oil and the extent to which they are accumulated and retained by the Manila clam.
