PCB


PCB

P0128700 (pē′sē-bē′)n. Any of a family of industrial compounds produced by chlorination of biphenyl, used as insulating materials in electrical equipment, including transformers and capacitors, and in various other industrial applications. PCBs were banned in the United States in 1979 and now are noted primarily as environmental pollutants that accumulate in animal tissue with resultant pathogenic and teratogenic effects.
[p(oly)c(hlorinated) b(iphenyl).]

PCB

abbreviation for (Elements & Compounds) polychlorinated biphenyl

biphenyl

 [bi-fen´il] diphenyl.polybrominated biphenyl (PBB) any of various brominated derivatives of biphenyl; uses and toxic hazards are similar to those of polychlorinated biphenyls. They typically are deposited in body fat stores and are rarely mobilized except through lactation.polychlorinated biphenyl (PCB) any of various chlorinated derivatives of biphenyl, toxic and carcinogenic nonbiodegradable compounds used as heat-transfer agents and electrical insulators; they are readily absorbed from the gastrointestinal tract, and those with a lower percentage of chlorine are associated with a higher toxicity but are more readily excreted.
