This guidance provides an overview of polychlorinated biphenyls (PCB), including their characteristics, historical uses, regulatory obligations under the Stockholm Convention and the many applications in which they have been found.
It focuses on PCB in open applications, particularly in buildings and industrial settings, where they often remain undetected and are not consistently managed as hazardous waste despite posing potential risks to human health and the environment.
The document also outlines practical approaches for identifying and ensuring the environmentally sound management of PCB across materials and sectors, emphasizing awareness, proper handling and the prevention of environmental releases throughout their lifecycle.
