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.

It is shown that lightly chlorinated biphenyls were the main PCB species, and PCB-11, 77, 28, and 15 were the most abundant congeners produced during the dye manufacturing processes.
The less abundant PCBs were still the lightly chlorinated biphenyls, including PCB-15, two indicator PCB congeners (PCB-52 and PCB28), and one dioxin-like PCB congener (PCB-77) with mean concentrations of 241.6, 249.1, 173.5, and 114.4 pg/L, respectively.
The mixture of Aroclor 1016 and Aroclor 1260 contained a wide range of chlorinated biphenyls and was used to validate the analytical method.
Analysis of the conformational mobility, molecular electrostatic potential, and dipole moment of chlorinated biphenyl: searching for the rationalization of the selective toxicity of polychlorinated biphenyls (PCBs).
