PCBbelastete

PCBbelastete refers to materials, devices, or locations that are contaminated with polychlorinated biphenyls (PCBs). PCBs are a group of synthetic chlorinated hydrocarbons that were widely used for their insulating and fire-retardant properties in electrical equipment, hydraulic fluids, and in various building materials. Because of their persistence and toxicity, PCBs are now subject to strict regulation in many jurisdictions.

Common sources include old transformers and capacitors containing PCB fluids, PCB-containing sealants and paints in older buildings, and soils and sediments near former industrial sites where PCBs were released.

Health and environmental implications: PCBs resist degradation, bioaccumulate in the food chain, and exposure has been linked to cancer and adverse effects on the immune, reproductive, and nervous systems. Management of PCBbelastete materials requires specialized handling, protective measures, and disposal through licensed facilities.

Regulatory context and disposal: PCBs are listed under international and national environmental regulations such as the Stockholm Convention and EU regulations. Decommissioning or renovation of PCBbelastete equipment typically involves professional removal, safe transport as hazardous waste, and disposal or destruction by approved facilities, often after lab analysis of PCB content. Remediation may involve removal of contaminated materials, encapsulation, or treatment of soils and sediments.
