Polychlorinated biphenyls (PCBs) are a gathering of artificial synthetics. They are slick fluids or solids, clear to yellow in shading, with no smell or taste. PCBs are entirely steady blends that are impervious to outrageous temperature and strain. PCBs were utilized broadly in electrical gear like capacitors and transformers. They additionally were utilized in pressure driven liquids, heat move liquids, greases, and plasticizers.
