Analytical Aspects for Determination of Polybrominated Diphenyl Ethers in Environmental Samples
Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants (BFRs) which 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 their occurrence and observed increasing temporal trends in the environment and in human biota. ...
متن کاملDetermination of polybrominated diphenyl ethers in soil and sediment from an electronic waste recycling facility.
Soil and sediment collected in the vicinity of an open electronic waste disposal and recycling facility located in Guiyu, Guangdong, China, were analyzed for the levels of common polybrominated diphenyl ethers (PBDEs) by using soxhlet extraction and gas chromatography/mass spectrometry. The PBDEs were detected in the soil and sediment samples at levels of 0.26-824 ng/g (dry weight). The obtaine...
متن کاملMethod development for the analysis of polybrominated diphenyl ethers, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins and dibenzo-furans in single extract of sediment samples.
A comprehensive method was developed for quantitative analysis of polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and dibenzo-furans (PCDD/Fs) in one single extract of environmental samples. The sample preparation procedure included two fractionation steps using silver nitrate silica chromatography to separate PBDEs from PCBs and PC...
متن کاملHeightened biological uptake of polybrominated diphenyl ethers relative to polychlorinated biphenyls near-source revealed by sediment and plankton profiles along a coastal transect in British Columbia.
Polychlorinated biphenyl (PCB) and polybrominated diphenyl ether (PBDE) concentrations and profiles in paired sediment-plankton samples were determined along a 500 km transect in coastal British Columbia, Canada. PCB and PBDE levels in sediment were both greater in the industrialized Strait of Georgia than in remote northern sites and exhibited parallel spatial trends. In plankton, recent-use P...
متن کاملReductive debromination of polybrominated diphenyl ethers in anaerobic sediment and a biomimetic system.
Because of the bioaccumulation of penta- and tetrapolybrominated diphenyl ether (PBDE) flame retardants in biota,the environmental biotransformation of decabromodiphenyl ether (BDE-209) is of interest. BDE-209 accounts for more than 80% by mass of PBDE production and is the dominant PBDE in sediments. Most sediments are anaerobic and reports of microbial reductive dehalogenation of hydrophobic ...
