The purpose of this session is to provide historical and regulatory context to the issue, describe the changes, challenges, and solutions needed for effective source control of PCB. The goal is to provide insight into the design of PCB free pigments that meet green chemistry principles, and to outline a transition path from research to development to market: the mechanisms, barriers, and implementation. The challenge of reducing Polychlorinated Biphenyls (PCBs) at the source is a national, even global issue as PCBs are globally transported, do not easily degrade, and bioaccumulate in the food chain. PCBs are ubiquitous in the environment, not only as the result of legacy uses of Aroclors but, significantly, from residual PCBs that are still being legally produced as "inadvertent contaminants" in industrial processes. A specific example is PCBs in pigments used in inks, dyes, and other products.
