Microbial Reductive Debromination of Polybrominated Diphenyl Ethers (PBDEs)
Environmental Science & Technology, 2006Polybrominated diphenyl ethers (PBDEs) are a class of widely used flame retardants that have recently been detected in environmental samples, diverse biota, human blood serum, and breast milk at exponentially increasing concentrations. Currently, little is known about the fate of these compounds, and in particular, about the microbial potential to ...

Polybrominated diphenyl ethers in house dust in Singapore
Chemosphere, 2007The use of polybrominated diphenyl ethers (PBDEs) as flame retardants in Singapore is not strictly regulated; therefore these compounds can be readily found in furniture, electronic devices, and building materials. This study was the first of its kind to be conducted in Singapore to measure concentrations of PBDEs in house dust.

Polybrominated Diphenyl Ethers: Neurobehavioral Effects Following Developmental Exposure
NeuroToxicology, 2003Polybrominated diphenyl ethers (PBDEs), a class of widely used flame retardants, are becoming widespread environmental pollutants, as indicated by studies on sentinel animal species, as well as humans. Of particular concern are the reported increasingly high levels of PBDEs in human milk, as should be given that almost no information is available on ...

Polybrominated diphenyl ethers (PBDEs) are a group of brominated flame retardants (BFRs) used mainly as additives in different kinds of plastic material. Various PBDEs are found in all environmental compartments as well as in tissue and blood serum of animals and humans due to their persistence and tendency to bioaccumulate.

Biodegradation of Polybrominated Diphenyl Ethers: A Minireview
Archives of Clinical and Medical Microbiology, 2022Polybrominated diphenyl ethers (PBDEs) are commonly regarded as the Persistent Organic Pollutant (POP). PBDEs are ubiquitous, flame retardants widely found in synthetic polymers, clothing, plastics. PBDEs are threat to the safety of environment and health.

Journal of Chromatography A, 2014
A simple, cost-effective method is described for the analysis of polybrominated diphenyl ethers (PBDEs) in house dust using pressurized fluid extraction, cleanup with modified silica solid phase extraction tubes, and fluorinated internal standards. There are 14 PBDE congeners included in the method, some typically contained in the commercial mixtures ...

Vapor Pressures of the Polybrominated Diphenyl Ethers
Journal of Chemical & Engineering Data, 2000The supercooled liquid vapor pressures PL of 23 polybrominated diphenyl ether congeners were determined as a function of temperature with a gas chromatographic retention time technique. PL at 298.15 K ranged from 0.1 Pa for monobrominated diphenyl ethers to 10-6 Pa for heptabrominated diphenyl ethers.

Environmental Science & Technology, 2008
This review presents the electron impact (EI) and electron capture negative ionization (ECNI) mass spectra of the polybrominated diphenyl ether (PBDE) flame retardants and of their methoxy derivatives. Data from the literature are reviewed, and full spectra from our laboratory are reported to correct some of the errors that have crept into some ...

Polybrominated Diphenyl Ethers: Human Tissue Levels and Toxicology
2004PBDEs are being released to the environment in wastes from their production facilities, degradation, or leaching and volatilization from products that contain PBDEs during the product's useful life. Brominated diphenyl ether congeners BDE-47, -99, and -153 are ubiquitous in the environment and are regarded as the most dominant congeners present in ...

The characterization of polybrominated diphenyl ether
1995Abstract Commercially available polybrominated aromatic ethers have been analyzed by reversed phase high performance liquid chromatography. NMR spectra of material isolated by preparative methods served to identify the observed peaks as congeners of tetrabromo to nonabromo diphenyl ether. A bromination pathway was clearly indicated.
