While any halogen may halogenate a polyphenyl, chlorine and bromine are by far the more usual. They result in a large number of possible polychlorinated biphenyls syn. p.c.b.s, PCBs, PCB s), polyhalogenated biphenyls, and polyhalogenated terphenyls. No longer produced commercially, halogenated polyphenyls were widely used for their exceptional qualities as heat-transfer fluids, solvents, lubricants, dust suppressants, and fire retardants (some equipment that relies on these chemicals, like electrical transformers and capacitors, remains in use). [Pg.111]

Due to their extensive use and resistance to decomposition, halogenated polyphenyls are almost universal environmental contaminants, present in waste sites, sediments, the human body, water supplies, and elsewhere. They are associated with many toxic and biochemical effects including wasting syndromes, bone marrow diseases, atrophy, chloracne, hyperplasin, liver damage, and cancer. [Pg.111]

Most halogenated polyphenyls in transportation, then, derive not from product shipments but from decommissioned equipment, drained fluids, soils and debris from waste site and riverbed cleanups, demolition work, scrap metal disposal, contaminated textiles and absorbents, and other wastes. [Pg.111]
