“…Nevertheless, a more likely explanation is that BDE183 in the sediments was formed from microbial or photolytic debromination of highly brominated BDEs (Bezares-Cruz et al 2004;He et al 2006). Elevated contributions of BDE183 and 28 have also been found in riverine (but not in the estuarine) sediments in the Pearl River Delta but not in marine sediments from the East China Sea and Bohai Sea (Wang et al 2009;Li et al 2012b). Overall, the altered PBDE profiles in the sediments in the present study suggest that some congeners may have encountered degradation due to the reduced fresh inputs, especially in riverine buried sediments.…”

Polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in 25 surface sediments in three cities (Nantong, Wuxi, and Suzhou) in the Yangtze River Delta, eastern China were measured. The mean concentrations were 378, 45.8, 1.98, 4,002 ng/g for PBDEs, OCPs, PCBs, and PAHs, respectively. Their levels in the sediments in the three cities were generally consistent with the city industrialization. PBDEs and OCPs were markedly dominated by deca-BDE (>90 %) and DDTs (>70 %). A principle component analysis of the analytes identified three major factors suggesting different sources of the contaminants in the sediments. PBDEs and the organic carbon in the sediments have common sources from industrial activities; whereas OCPs and PCBs, correlated with the second factor, were mainly from historical sources. The third factor with loadings of PAHs is indicative of various combustion sources. Ecological risk assessment indicated that the potential highest risk is from DDTs, for which 22 sites exceed the effects range low (ERL) values and three sites exceed the effects range median (ERM) value.

“…It is well-known that TBBPA and BPA are linked with endocrine-disrupting activities (Li et al 2012a) and can mimic or antagonize the biological function of natural hormones (Kitamura et al 2005). The European Commission has set the threshold of endocrine disrupting effects at 1 ng E 2 L -1 , meaning that when the total E 2 EQ of any individual endocrine-disrupting chemical exceeds 1 ng E 2 L -1 , that chemical may affect the endocrine systems of aquatic organisms in the receiving water environments (EU Commission 1996).…”

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.

“…They have been extensively used as flame retardants in, for example, plastics, electronic appliances, furniture and vehicles [1,2]. As a result of massive industrial use, PBDEs have been detected in a wide variety of environmental media such as air [3], soil [4], sediment and sewage sludge [5] as well as biological samples including birds [6], fish [7], human blood serum and breast milk [8]. PBDEs are found even in the Arctic biosphere [9].…”
