Metabolism in the toxicokinetics and fate of brominated flame retardants—a review

" In April 2000 researchers from around the world met in Lexington, Kentucky to bring together the very latest information on the chemistry and biological effects of the environmental pollutants known as Polychlorinated Biphenyls (PCBs). The result is a comprehensive and extensive treatment of the very latest findings on all significant subjects relating to PCBs and their health risks. The thorough introduction and sixty-two scientific papers presented here represent the most up-to-date research by scientists in government, private industry, and academia.

Toxicological profile for polybrominated biphenyls and polybrominated diphenyl ethers

Disposition and excretion of 2,3,7,8-tetrachlorodibenzofuran in the rat.

Polyhalogenated biphenyls induce microsomal mixed-function oxygenases in many species including man. They can be divided into two classes of inducers. 3,4,5,3',4', 5'-Hexa- and 3,4,3',4'-tetrachlorobiphenyls appear to interact with the TCDD receptor, albeit at 100 to 1,000 times the dose. The structure required for 3-MC (TCDD)-type induction seems to be the presence of at least two adjacent halogens in the lateral positions (meta and para) of the benzene rings, and an absence of halogens in the ortho positions adjacent to the biphenyl bridge. It is likely that halogenation of the ortho positions prevents binding by blocking planar configuration. These isomers, although less toxic than TCDD, are much more toxic than other PCB isomers. Most halogenated biphenyl isomers are phenobarbital type inducers or are inactive. The structure-activity relationship for this type of induction is less clear, but active isomers include 2,4,2',4'-tetra-; 2,4,5,2',4',5'-; 2,3,4,2',3',4'-; 2,3,5,2',3'.5'-and 2,4,6,2',4',6'-hexachlorobiphenyls and 2,4,5,2',4',5'-hexabromobiphenyl. The inactivity of many of the lower chlorinated isomers as inducers (mono-through tetrachloro-) may be related to their rapid metabolism. The cytochrome which is induced by commercial PCB and PBB mixtures appears to be identical to a mixture of cytochromes from phenobarbital- and 3-MC-treated rats. These structure-activity relationships suggest that the "mixed inductive" effects and much of the toxicity of PCB and PBB mixtures are due to the presence of compounds related structurally to the active chlorinated dibenzofurans or 3,4,3',4'-tetrachlorobiphenyl.

The structure-activity relationships of halogenated biphenyls as enzyme inducers.

The intestinal absorption, distribution, and excretion of the major component of Firemaster BP-6,2,4,5,2',4',5'-hexabromobiphenyl, has been studied in the male rat This polybrominated biphenyl was readily absorbed from the intestine, initially distributed throughout the body, and eventually stored primarily in the adipose tissue, was not subject to appreciable metabolism, and was excreted almost exclusively in the feces and at a very slow rate Approximately 90% of an oral dose was absorbed from the intestine, and extrapolation of the rate of excretion to infinity indicates that less than 10% of the total dose would ever be excreted
