We report measurements of polybrominated diphenyl ethers and of emerging flame retardants in the plasma of nestling bald eagles sampled from early May to late June of 2005. Concentrations of total PBDEs ranged from 0.35 ng g(-1) ww to 29.3 ng g(-1) ww (average=5.7+/-1.9 ng g(-1) ww). The most abundant congeners were BDE-47, BDE-99, and BDE-100. The fully brominated congener, BDE-209, was detect...

Using Raman spectroscopy without any preparation, we analyzed the brominated flame retardant, polybromodiphenyl ethers (PBDEs), which has been prohibited by the European Union. The typical Raman bands of PBDEs, which are clearly different from those of other brominated flame retardants, are from 100 to 300 cm(-1). In our analysis, the detection limit was about 100 ppm, and the analysis took abo...

The title compound (OctaInd), C(18)H(12)Br(8), is a commercial brominated flame retardant (BFR). In the mol-ecule, the five-membered ring has a slight envelope conformation, with a deviation of 0.317 (9) Å for the flap C atom from four essentially planar C atoms. The dihedral angle between the two benzene rings is 74.00 (16) Å.

Introduction Brominated flame retardants (BFRs) are a group of compounds that are added to a wide range of products, such as printed circuit boards, computer cases, electronic appliances, automobiles and construction materials to prevent the outbreak of fire. Among them, additive flame retardants like polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) are the focus of cu...

Brominated flame retardants (BFRs) have routinely been added to consumer products for several decades in a successful effort to reduce fire-related injury and property damage. Recently, concern for this emerging class of chemicals has risen because of the occurrence of several classes of BFRs in the environment and in human biota. The widespread production and use of BFRs; strong evidence of in...

polybrominated diphenyl ethers as flame retardants prevent the branching mechanism of free radicals in gas phase during the combustion. therefore, they are used in electric and electronical instruments. these supplies are entering the landfills after use. the existing flame retardants in these landfills enter the air, water and soil and pollute them. in this paper a mass-transfer model is devel...

As polybrominated diphenyl ethers (PBDEs) face increasing restrictions worldwide, several alternate flame retardants are expected to see increased use as replacement compounds in consumer products. Chemical analysis of biosolids collected from wastewater treatment plants (WWTPs) can help determine whether these flame retardants are migrating from the indoor environment to the outdoor environmen...
