PPT-BACKGROUND: Polychlorinated biphenyls (PCBs) are known as

neurotoxic chemicals or endocrinedisrupting compounds The non Aroclor congener 33dichlorobiphenyl PCB11 has been detected ubiquitously in air water biota sediment and suspended sediment since at least the 1970s However this congener was produced inadvertently during the production of current commercial yellow paint pigments the detailed effects of this congener on .
