Bioavailability and Bioaccumulation of Sediment-Bound Polychlorinated Biphenyls to Carp

Abstract : The relative bioavailability of sediment-bound polychlorinated biphenyls (PCBs 138, 153, and 180) from a local contaminated site was examined using an in vivo carp model. Surface sediment from the PCB-contaminated site and spiked canola oil containing equivalent masses of PCBs were respectively incorporated in the sediment-dosed diets and oil-dosed diets at 3 dose levels resulting in 6 experimental diets. Juvenile carps (n=90) were divided in 18 tanks (5 fishx6 treatmentsx3 tanks). Fish were fed the control diet during the adaptation period (15 d). Next, 1 fish was sampled in each tank and muscle tissues were combined in control groups. During the exposure period (15 d), the remaining fish were fed with 1 of the 6 experimental diets. At the end of the experiment, fish were sampled and muscle tissues were combined for each tank. The PCBs were monitored in feed and fish muscle. For both the contaminated sediment and spiked canola oil groups, concentrations of PCBs 138, 153, and 180 in muscle linearly increased with concentrations in food, with similar intercepts and slopes. In the present study, the sediment-bound PCBs were as bioavailable as those spiked into canola oil and fed to carp in a standard diet.
