“…The observed average concentrations of particulate 13 PBDEs ranged from 30.6 to 141.2 pg m −3 , with a mean value of 86.3 pg m −3 (Table 3). This result was consistent with the results of the previous measurements in Shanghai, 108-367 pg m −3 (Yang et al, 2013), and 104 ± 54 pg m −3 (Yu et al, 2011), but was much lower than in Beijing, 760 pg m −3 (Yang et al, 2013), and in waste recycling zones of Qingyuan close to Guangzhou, 3260 pg m −3 (Tian et al, 2011). In addition, these results were compared with those reported in aerosol samples from Ontario (Larsen and Baker, 2003), Chicago (Hoh and Hites, 2005) and three different stations in western Europe (Lee et al, 2004), as well as other Asian cities such as Osaka (9.9-22.3 pg m −3 ) (Kakimoto et al, 2014), Busan (5.3-16 pg m −3 ; Rudich et al, 2007) and Singapore (7.5 pg m −3 ; Shen et al, 2013).…”

Abstract. In order to better understand the size distribution of particle-associated PBDEs and their deposition pattern in the human respiratory tract, we carried out a 1-year campaign during 2012-2013 for the measurement of sizeresolved particles at the urban site of Shanghai. The results showed that particulate PBDEs exhibited a bimodal distribution with a mode peak in the accumulation particle size range and the second mode peak in the coarse particle size ranges. As the number of bromine atoms in the molecule increases, accumulation-mode peak intensity increased while coarsemode peak intensity decreased. This change was consistent with the variation of PBDEs' subcooled vapor pressure. Absorption and adsorption processes dominated the distribution of PBDEs among the different size particles. The evaluated deposition flux of 13 PBDEs was 26.8 pg h −1 , in which coarse particles contributed most PBDEs in head and tracheobronchial regions, while fine-mode particles contributed major PBDEs in the alveoli region. In association with the fact that fine particles can penetrate deeper into the respiratory system, fine-particle-bound highly brominated PBDEs can be inhaled more deeply into human lungs and cause a greater risk to human health.

“…Within the DecaBDE category, BDE-209 was the main congener, ranging from 41.65 to 97.13 % of total PBDEs, with the exception of samples collected at S2 (31.39 %) and S5 (21.63 %). This finding is in agreement with the lack of restrictions on DecaBDE production or use in most countries, whereas Deca-BDE is a main element of BFR production in China (Yu et al 2011).…”

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.

“…Once in the environment, DP would undergo long-range atmospheric transport to even remote regions of the world (Hoh et al, 2006;Möller et al, 2010). As a result of its historic and continued use, tendency for long-range atmospheric transport, and hydrophobicity, DP has been found in a wide variety of biota and abiotic environment samples (Gauthier and Letcher, 2009;Guerra et al, 2011;Hoh et al, 2006;Qiu and Hites, 2008;Sverko et al, 2010;Wang et al, 2010;Yu et al, 2010Yu et al, , 2011. Furthermore, an increasing body of evidence suggests that DP readily accumulates within biological tissues (Jia et al, 2011;Shen et al, 2011;Wu et al, 2010) and is biomagnified through food webs (Tomy et al, 2007;Wu et al, 2010).…”
