ABSTRACT
PCB stands for polychlorinated biphenyls or simply chlorinated biphenyls. Though PCBs can be considered as part of a broader group of chemicals known as chlorinated hydrocarbons, considering the sources, the fate, and the behavior of PCBs in the environment, they have been included among the persistent organic pollutants (POPs). The main features of these pollutants are that they are toxic, persistent, bioaccumulative, and prone to long-range transport.
