Analysis of polybrominated biphenyls

Journal of Chromatography A, 1977
High-performance liquid chromatography, gas chromatography-mass spectrometry, ultraviolet spectrometry and nuclear magnetic resonance spectrometry have been used to characterize the behaviour of a number of individual brominated biphenyls and to assess the composition of several mixtures of these compounds.

Polybrominated Biphenyls and Diphenylethers

2000
Polybrominated biphenyls (PBBs) and polybrominated diphenylethers (PBDEs), also called brominated diphenyl oxides, are produced and used as flame retardants. There are theoretically 209 different congeners of both PBBs and PBDEs. These congeners have specific chemical and physical properties, which lead to different biological and toxicological effects.

Developmental neurotoxicity of polybrominated biphenyls

Neurotoxicology and Teratology, 1994
Female F0 generation Sprague-Dawley rats received daily oral doses of 0, 0.2, or 2 mg/kg polybrominated biphenyls (PBB) as fireMaster BP-6 from Day 6 of gestation through Day 24 postpartum. Maternal parameters were assessed, and F1 generation offspring were evaluated for growth and survival, as well as physical and behavioral development.

Purification of polybrominated biphenyl congeners

Journal of Toxicology and Environmental Health, 1982
A commercial preparation of polybrominated biphenyls (Firemaster BP-6) was fractionated by preferential acetone solubilization and a number of PBB congeners were purified from the resulting fractions by repeated recrystallization, alumina adsorption column chromatography, and reversed-phase Lipidex-500 column chromatography.

Exposure to Polybrominated Biphenyls

JAMA, 1979
Twenty-one persons exposed to polybrominated biphenyls (PBB) were compared with hospital volunteers on a battery of tests measuring memory, motor strength and coordination, cortical-sensory perception, personality, and higher cognitive functioning. Patients exposed to PBB were selected for this study only if they had persistent medical complaints.

Hypothyroidism in Workers Exposed to Polybrominated Biphenyls

New England Journal of Medicine, 1980
THE polybrominated biphenyls (PBB's) and polybrominated biphenyl oxides (FBBO's) are brominated hydrocarbons that have been used commercially as fire retardants.
