“…Sediments are composed of small organic and inorganic particles which show higher adsorption capacities for PBDEs due to their large surface area. In addition, the strong hydrophobic properties of PBDEs allow them to accumulate in sediment (Binelli et al 2007). The most polluted sediment sample in our study was from S6 and S7, where R 20 PBDEs concentrations were as high as 6.0 9 10 3 ng g -1 .…”

The aim of this study was to assess the pollution profiles of various typical brominated flame retardants in water and surface sediment near a typical electronic waste dismantling region in southern China. We found that polybrominated diphenyl ethers (PBDEs), 2,4,6-tribromophenol (TBP), pentabromophenol (PeBP), tetrabromobisphenol A (TBBPA), and bisphenol A (BPA) were ubiquitous in the water and sediment samples collected in the study region. In water, R 19 PBDEs (sum of all 20 PBDE congeners studied except BDE-209, which was below the detection limit) levels ranged from 0.31 to 8.9 9 10 2 ng L -1 . TBP, PeBP, TBBPA, and BPA concentrations in the water samples ranged from not being detectable (nd-under the detection limit) to 3.2 9 10 2 (TBP), from nd to 37 (PeBP), from nd to 9.2 9 10 2 (TBBPA) and from nd-8.6 9 10 2 ng L -1 (BPA). In sediment, R 19 PBDEs ranged from nd to 5.6 9 10 3 ng g -1, while BDE-209 was the predominant congener, with a range of nd to 3.5 9 10 3 ng g -1. Tri-to hepta-BDE concentrations were significantly (p \ 0.01) correlated with each other, except for BDE-71 and BDE-183, and octa-to nona-BDEs concentrations were significantly (p \ 0.05) correlated with each other, except for BDE-208. BDE-209 was not significantly correlated with tri-to nona-BDEs. Risk assessments indicated that the water and sediment across the sampling sites posed no estrogenic risk. However, different eco-toxicity risk degrees at three trophic levels did exist at most sampling sites.

“…All of the analytes were separated by a Rtx-5MS (Restek, Bellefonte, PA) capillary column (30 m length, 0.25-mm i.d., 0.25 lm df) under the following conditions specified by Binelli et al (2007): carrier gas helium at 1.2 mL/min; injection pressure of 120 kPa; transfer pressure of 240 kPa; injector temperature starting at 70°C and maintained for 1.2 min, then ramped to 280°C (held 1.2 min) at 14°C/s; initial oven temperature set at 70°C (held 1 min), then ramped to 220°C at 30°C/min (held 1 min), and finally to 290°C at 4°C/min (held 20 min). The samples were analyzed using tandem mass spectrometry under the following instrumental conditions: the electric ionization mode with standard electron energy of 70 eV was used, and the transfer line was maintained at 280°C, the damping gas at 2 mL/min, and the ion source at 260°C.…”

This study investigates contamination by 13 polybrominated diphenyl ether (PBDE) congeners in a high-mountain pasture located in the Italian Alps. The trend of PBDE contamination in three soil layers was investigated by a spring-summer sampling period to understand the importance of different environmental variables, such as seasonality, topographical aspect, and soil features. We also evaluated PBDE accumulation in grasses covering the plateau, and because the study area has been used for a pasture for a long time, we measured PBDE levels in milk from grazing cows. Overall, we found moderate PBDE contamination in Andossi soils, with differences depending on the layer, mountain side, and organic matter content. The vegetation of the plateau had greater PBDE concentrations than the soils and showed a grass/soil accumulation ratio between 2 and 12, indicating that deposition from the atmosphere is actually the dominant process in this area. Last, PBDE concentrations in milk followed similar seasonal trends as the vegetation but showed variations in congener abundance in agreement with the biotransformation susceptibility, absorption efficiency, and residence time of different BDEs in dairy cattle.

“…PBDEs are a group of brominated compounds that widely used as flame-retardants in furniture and consumer products. The concentration of PBDEs in sediments have increased from the 1960s or 1970s to the 1990s in Europe, North America and Asia (Binelli et al, 2007;Chen et al, 2007;Hites and Zhu, 2005;Sakai et al, 2002;Song et al, 2005;Zegers et al, 2003). Although the use of penta-and octa-BDEs has been restricted in the European Union and in certain parts of the United States (Renner, 2004), a vast number of products containing PBDEs still remain in use.…”
