Chemistry and Behavior PCBs are synthetic organic chemicals, complex mixtures of individual chlorobiphenyls that contain 1 to 10 chlorine atoms. PCBs bind strongly to organic particles in the water column, atmosphere, sediments, and soil. As the compounds move through the environment, the absolute and relative concentrations of individual chlorobiphenyls change over time and from one environmental medium to another because of physical and chemical processes and selective bioaccumulation and metabolism by living organisms. These processes result in mixtures substantially different from the original mixtures that were released to the environment. Identification, quantification, and risk assessment are complicated by these changes in the composition of the PCB mixtures. Analytical Chemistry of PCBs, 2nd ed.
