The relationship of sediment-bound polychlorinated biphenyl (PCB) 153 and fluoranthene to bioaccumulation by worms and clams and the relationship of sediment-bound PCB 153 and fluoranthene to concentrations in the interstitial water were examined. Bioaccumulation by both worms and clams was observed in all sediments. Apparent preference factor (APF) values showed that steady state was reached between sediment-bound contaminants and organism lipid pools. The APF values of organisms were close to the theoretical value for both contaminants in all sediments. These results showed that sediment total organic carbon (TOC) in conjunction with octanol water partition coefficients of nonpolar organic contaminants is a viable approach for predicting bioaccumulation of such compounds by infaunal organisms. Actual concentrations of contaminants in interstitial water were either overestimated or underestimated by the relationship between TOC and humic + fulvic acid organic matter fractions and sediment contaminant concentrations. Prediction of interstitial water concentrations was not as successful as use of APFs. The lack of agreement between predicted and actual interstitial water results was due to factors such as the presence of interstitial water contaminants bounds to microparticulates and dissolved organic material and the kind of organic material in the sediment.
