Contaminated Sediment as a Source of PCB in a River System


The transport of PCBs (Aroclor 1242) in a river system in southern Sweden was governed by outflow from sediment in a 26-ha contamined lake. Experiments in the lake revealed that 14 g PCBs/d escaped from the sediment, while sedimentation was 3 g PCB/d. Volatilazion of PCBs from the lake surface was 0,02 g/d, which was considerably higher than the atmospheric fallout
