There are several factors that affect PCB bioaccumulation. These include: concentration in the surrounding environment; duration of exposure; temperature; solubility of the pollutant; species age, weight, feeding habits and lipid content; trophic level variations; and adsorption. Bioaccumulation can occur either through ingestion of contaminated food organisms or by direct absorption through the integument. Higher concentrations of PCBs have been found in plankton than in fish, indicating that direct absorption is the primary route of accumulation. This investigation was conducted to follow the uptake and concentration factor (CF) of Aroclor 1254 in selected organisms representing a simple aquatic ecosystem.
