"The uptake and depuration of 37 chemicals from spiked Lake Ontario sediments by oligochaete worms has been studied at 8° and 20°C in laboratory aquaria. The worms were found to rapidly accumulate the chemicals and reach peak concentrations within two weeks. The concentration of chemicals in the sediment pore water appeared to be the major factor controlling the bioconcentration of chemicals by the worms"--Abstract.
