“…The ranges of BDE 209 concentrations in this study were higher than those detected in three bays from South America and in the western Arctic Ocean (Table 2). However, the concentrations of BDE 209 in this study were lower than those detected in other coastal areas of China during previous studies (Wang et al, 2011;Yang et al, 2004). Compared with other studies on coastal and marine sediments in China (Table 2), relatively low concentrations of P PBDEs (mean 0.09 ng g À1 dw) and P aBFRs (mean 0.02 ng g À1 dw) were observed in this study.…”

“…Previous studies of BFRs in northern China focused mainly on PBDEs in sediments (Lv et al, 2015;Pan et al, 2011;Wang et al, 2011Wang et al, , 2009Yang et al, 2004), and no data on levels of aBFRs were found in this area. Table 1 and Table S1 shows the BFRs concentrations in Dalian Bay, Jiaozhou Bay, Taozi Bay, and Sishili Bay along with the concentrations in the two Rivers (Qingdao River and Dagu River) around Jiaozhou Bay.…”

a b s t r a c tThe distribution characteristics and potential sources of polybrominated diphenyl ethers (PBDEs) and alternative brominated flame retardants (aBFRs) were investigated in 54 surface sediment samples from four bays (Taozi Bay, Sishili Bay, Dalian Bay, and Jiaozhou Bay) of North China's Yellow Sea. Of the 54 samples studied, 51 were collected from within the four bays and 3 were from rivers emptying into Jiaozhou Bay. Decabromodiphenylethane (DBDPE) was the predominant flame retardant found, and concentration ranged from 0.16 to 39.7 ng g À1 dw and 1.13e49.9 ng g À1 dw in coastal and riverine sediments, respectively; these levels were followed by those of BDE 209, and its concentrations ranged from n.d. to 10.2 ng g À1 dw and 0.05e7.82 ng g À1 dw in coastal and riverine sediments, respectively. The levels of DBDPE exceeded those of decabromodiphenyl ether (BDE 209) in most of the samples in the study region, whereas the ratio of DBDPE/BDE 209 varied among the four bays. This is indicative of different usage patterns of brominated flame retardants (BFRs) and also different hydrodynamic conditions among these bay areas. The spatial distribution and composition profile analysis indicated that BFRs in Jiaozhou Bay and Dalian Bay were mainly from local sources, whereas transport from Laizhou Bay by coastal currents was the major source of BFRs in Taozi Bay and Sishili Bay. Both the P PBDEs and P aBFRs (sum of pentabromotoluene (PBT), 2,3-diphenylpropyl-2,4,6-tribromophenyl ether (DPTE), pentabromoethylbenzene (PBEB), and hexabromobenzene (HBB)) were at low concentrations in all the sediments. This is probably attributable to a combination of factors such as low regional usage of these products, atmospheric deposition patterns, coastal currents transportation patterns, and degradation processes for higher BDE congeners. This paper is the first study that has investigated the levels of DBDPE in the coastal sediments of China's Yellow Sea.

“…For HCHs and DDTs, the residue levels found in this study were well within the worldwide ranges. The levels of P 9 PBDEs in Taihu Lake were comparable to those reported in river/sea sediments in China, such as the Yangtze River Delta (n.d-0.55 ng/g) (Chen et al, 2006), the South China Sea (0.04-94.7 ng/g) (Mai et al, 2005), and nearshore sediments of Qingdao (0.1-5.5 ng/g) (Yang et al, 2004). These levels were also close to those found in the Ebro river basin (NE Spain) (n.d-20.9 ng/g) (Lacorte et al, 2006), but were higher than those of the Danube Delta (<0.1 ng/g) .…”

“…ΣPBDE (sum of BDE-17, 28, 47, 66, 71, 85, 99, 100, 138, 153, 154 and 183) and BDE209 concentrations in sediments were within the ranges of 0.1-0.5 ng/g and ND-14.9 ng/g (d.w.), respectively. The concentrations were close to those in Qingdao inshore sediments [10] , but much lower than those of Zhujiang Delta [11] .

Contamination trends of polybrominated diphenyl ethers, organochlorine pesticides and heavy metals in sediments from Dagu Drainage River estuary, Tianjin

Concentrations of polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (OCPs) and heavy metals in two sediment cores, taken from the Dagu Drainage River, were determined. The contamination trends of these three kinds of compounds were obtained. The results showed that concentrations of PBDEs increased in recent years; there were new contamination sources for OCPs in this area; contamination levels of heavy metals had no significant change in the last several years. Comparing the results of these two cores, erosion and dilution of seawater had different effects on the transportation of these compounds.
