Abstract Food chain transfer of polychlorinated biphenyls (PCBs) was studied by feeding contaminated fungus,Fusarium oxysporum, to the amphipod,Gammarus tigrinus, both isolated from the Hudson River. Apparent distribution coefficients (μg PCB/g dry wt. fungus // μg PCB/g medium) of 1.14–1.33 × 103 were determined when14C-Aroclor 1254 at 0.007 μg/g was added to 4-day old fungal growth for 24 hr. InG. tigrinus fed contaminated fungus, cross-gut PCB assimilation was indicated. Rapid PCB uptake occurred with a constant level achieved between 9 and 24 hr. Over a period of 144 hr, 57% of accumulated PCBs were eliminated. The results suggest that dietary uptake may contribute substantially to PCB levels inGammarus.
