|Description||It has long been known that polychlorinated biphenyls (PCBs) are inadvertently generated during manufacture of some pigments. This has become more of an issue in Washington State because of allowances of up to 50 ppm PCBs in most products under the federal Toxics Substances Control Act (TSCA) and much lower allowances for PCBs in waterways under the Clean Water Act (CWA). PCBs are addressed in the state PBT Rule (WAC 173-333) on persistent, bioaccumulative and toxic chemicals (PBTs) that remain in the environment and people for a long time and build up within organisms and in the food chain. It is beneficial to reduce sources of PBTs like PCBs wherever possible to reduce exposure to people and the environment. There are many challenges to PCB-free pigments, which must show potential to be used for widely distributed applications, including large-volume, low-cost printing of magazines, newspapers, and architectural paints.|
