Uptake of trace metals by the clam Macoma inquinata from clean and oil-contaminated detritus

A detritivorous clam, Macoma inquinata, was exposed to clean and Prudhoe Bay crude oil-contaminated detritus to determine the effect of oil on radiolabelled metal accumulation (Cr, Co, Eu, Fe, Sc and Zn.) There was no evidence to suggest that exposure to 1000 ppm petroleum hydrocarbon either increas...

Zusammenfassung:A detritivorous clam, Macoma inquinata, was exposed to clean and Prudhoe Bay crude oil-contaminated detritus to determine the effect of oil on radiolabelled metal accumulation (Cr, Co, Eu, Fe, Sc and Zn.) There was no evidence to suggest that exposure to 1000 ppm petroleum hydrocarbon either increased or decreased the rate at which the clam absorbs the metals, other than through a decrease in the rate of food intake. Crude oil in sediment might affect the condition of the clams through an effect on feeding behaviour, but an increased risk of heavy metal toxicity to the clam population was unlikely. Nevertheless, oil contamination could alter patterns of metal transfer in the marine benthic community and change the food web owing to changes in the feeding behaviour.
