安全信息

毒性	Mixtures of brominated biphenyls with an average bromine content of six atoms per molecule. PBBs have been used as flame retardants, but in view of environmental and health problems such use is being curtailed. Acute toxicity is low; rats given single oral doses of 17 g/kg exhibited no toxic effects. Most poisonings are due to chronic exposure. Chronic doses of 67 mg/kg/day produced anorexia, diarrhea, lachrymation and salivation, dehydration and abortion in pregnant cows.
