NCIt related terms : HEXABROMOBIPHENYL (MIXED ISOMERS);
NCIt definition : A mixture of synthetic solids, containing three or more bromine atoms, that is virtually
insoluble in water but is soluble in fat and various organic solvents. There are 209
different molecular combinations, or congeners, that are possible for polybrominated
biphenyls. These mixtures are no longer used or produced in commercial quantities
in the United States. Residues remaining in and around plants that formerly manufactured,
processed or produced products using polybrominated biphenyls are the current sources
for human exposure. The primary routes of potential human exposure to polybrominated
biphenyls are ingestion, inhalation, and dermal contact. A commercial mixture of these
compounds is reasonably anticipated to be a human carcinogen. (NCI05);
