Chemistry of PCBs and PBBs
Introduction A recent book by Hutzinger et al. (1) reviews the chemistry of chlorinated biphenyls through the end of 1973. This wide-ranging review also includes discussions of metabolism and determination of chlorinated biphenyls. The present report reviews areas of chlorobiphenyl and bromobiphenyl chemistry held to be pertinent to the Subcommittee's concern for possible health effects of thes...
متن کاملMetabolism and biochemical toxicity of PCBs and PBBs
One of the major biochemical effects of PCBs is the induction of microsomal enzymes in the liver. Risebrough et al. (1) suggested that PCBs have the capability to induce the activities of microsomal enzymes. Subsequently, Street et al. (2), demonstrated the induction of liver enzymes in rats by PCBs. Since then, a great number of articles have been published on this subject. The enzyme systems ...
متن کاملBody Burden Reductions of PCBS, PBBs and Chlorinated Pesticides in Human Subjects
With human exposure to environmental contaminants inevitable despite the best application of environmental laws and protection technologies, interest has grown in the potential to reduce the levels of contamination carried in the human host. This study demonstrates the promise of a comprehensive treatment for reduction of body burdens of polychlorinated and polybrominated biphenyis (PCB and PBB...
متن کاملEffects of PBBs on cattle. I. Clinical evaluations and clinical chemistry.
Toxicosis was induced in pregnant heifers by feeding 25,000 mg/head/day of FireMaster BP-6, a commercial blend of polybrominated biphenyls (PBB). The PBB feeding decreased dry matter intake approximately 50% by 4 days exposure. Emaciated animals became anorexic a few days prior to death at 33 to 66 days. Weight losses of heifers average 80 kg. Other clinical signs observed were dehydration, dia...
متن کاملPBBs, PBDEs, and PCBs in foods collected from e-waste disassembly sites and daily intake by local residents.
This study was conducted to estimate the total daily dietary intakes (TDIs) of three PHAHs subfamilies for residents living around the large e-waste disassembly sites in the Zhejiang province of China. A total of 191 food samples (including seven food groups and drinking water) were obtained from the disassembly sites and the control site in April, 2007. The levels of three PHAHs were measured ...
