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.

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.

Spatial analysis of polybrominated diphenylethers (PBDEs) and polybrominated biphenyls (PBBs) in fish collected from UK and proximate marine waters

Chemosphere, 2018
Some commonly consumed marine fish species are considered to display a higher risk of bio-accumulating organic environmental contaminants such as PBDEs.

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.

The accumulation of polybrominated biphenyls by fish

Bulletin of Environmental Contamination and Toxicology, 1977
In contrast to bromobiphenyls with up to 4 bromine atoms, which resemble quite closely the corresponding chlorobiphenyls, the more substituted bromobiphenyls are less accumulated by fish from water than the corresponding PCB's, represented by Aroclor 1254.

Retention and excretion of polybrominated biphenyls by hens

Bulletin of Environmental Contamination and Toxicology, 1976
The retention and elimination of PBB by hens are qualitatively similar to those of PCBs and chlorinated hydrocarbon pesticides. Steady-state level in eggs was about the same as the level in the diet, and after 63 days the level in body fat was about 4 times the level in diet.

Effects of Polybrominated Biphenyls on the Excretion of Steroids

Journal of Animal Science, 1983
When polybrominated biphenyls (fireMaster BP-6, PBB) are ingested by cattle, they have been shown to alter hepatic enzyme systems, and produce renal lesions with chronic high exposure. These changes provide mechanisms for alteration of the metabolism and clearance of steroid hormones that might then affect reproductive function.
