Accumulation and effects of cadmium were investigated in Chironomus thummi larvae exposed to 10, 100 and 250 mug radiolabeled Cd/1 for up to 4 days. (1) After 4 days, average cadmium accumulation was 6.6 ng Cd/mg dry weight (10 mug Cd/1 exposure) and 177 ng Cd/mg dry weight (250 mug Cd/1 exposure). (2) Dissection studies showed that by 32 hr of exposure to both cadmium concentrations, 63.5-81.4% of accumulated cadmium was confined to the posterior midgut epithelium.
