Persistence of polybrominated biphenyls (PBB) in human post-mortem tissue.
Polybrominated biphenyl (PBB), a fire retardant, was accidentally substituted for an animal feed supplement in Michigan 10 years ago. This led to widespread livestock contamination and ultimately to contamination of virtually every human residing in the State at that time. In order to evaluate the extent of PBB persistence and distribution in human tissues 10 years after this accidental poisoni...
متن کاملField concentrations and persistence of polybrominated biphenyls in soils and solubility of PBB in natural waters.
Soil samples were collected from 28 fields which had received manure from Michigan's most highly contaminated dairy herds. The number of fields in each concentration range of PBB in soil were: 2, not detectable; 15, 0.0 to 8.0 ppb; 6, 14-102 ppb, and 5, 153 to 371 ppb. Plant tissue sampled from the 10 most highly contaminated fields contained no detectable PBB. No evidence of significant degrad...
متن کاملEffects of polybrominated biphenyls (PBB) on immune response in rodents.
Studies were performed to investigate the effects of FireMaster FF-1, a chemical fire retardant consisting of a mixture of polybrominated biphenyls (PBB), on immune functions in mice and rats. Animals received 22 daily treatments of 0.03, 0.3, 3.0, or 30 mg PBB/kg body weight in a period covering 30 days. PBB exposure severely depressed cell mediated immunity in both mice and rats at the higher...
متن کاملEmbryotoxic effects of polybrominated biphenyls (PBB) in rats.
Pregnant Sprague Dawley rats were given 0, 0.25, 0.5, 1, 5, and 10 mg of a commercial polybrominated biphenyl, FireMaster BP-6 (PBB), in olive oil by gavage each day from days 7 through 15 of pregnancy. Laboratory chow and water were given ad libitum. Treatment with PBB had no significant effect on body weight gain, food and water consumption, and urine production. The mothers were killed on da...
متن کاملPolybrominated biphenyls in lactating Michigan women: persistence in the population.
Polybrominated biphenyls (PBB) were inadvertently introduced into livestock feed in Michigan in 1973, resulting in widespread contamination of the state's food supply. Details of this unfortunate incident have been extensively documented (Carter 1976; Meester 1979). Approximately 12 months after the spill, several reports demonstrated the presence of PBB in human tissues including fat and blood...
