Abstract
3,3’-Dichlorobiphenyl (PCB-11) is a polychlorinated biphenyl (PCB) congener that has attracted a lot of attention in recent years due to it being detected in the environment and its source not fully understood.
PCB-11 was not a significant congener within the PCB Aroclor mixtures that were banned from production because they were persistent organic pollutants (POPs). Research to determine the source of PCB-11 in the environment has focused on its inadvertent presence in organic pigments, principally diarylide pigments.
Other sources such as incineration, photochemical dechlorination of higher-level PCB congeners and other non-pigment-containing products could also explain the higher than anticipated level of PCB-11 within the environment.
