“…Comparing with data from the sediments near manufactory locations, the concentrations in the three bays were one to three orders of magnitude lower (Table 2). Wang et al (2010a, b) reported concentrations ranging from 1.86 to 8.0 ng g À1 dw in the canal sediments near Anpon Corporation in Huai'an, China, and Sverko et al (2008) reported high concentrations in sediment of Great Lakes ranging from 0.061 to 586 ng g À1 near the OxyChem company. According to Wang et al (2010a, b), DP was only manufactured by Anpon Corporation in Huai'an, China, which is 300- 500 km north of the study area.…”

“…The smallest Sishili Bay (130 km 2 ) stores most of DP (0.49 kg). Qiu et al (2007) reported the inventory of DP per area (9 cm and 16 cm depth) was 120 ng cm À2 in Lake Ontario, and Wang et al (2010a, b) calculated the 20.3 ± 7.5 cm soil inventory to be 15 000-110 000 ng cm À2 in Huai'an. The 5 cm depth burdens of DP were 8.5 ng cm À2 in Jiaozhou Bay, 20.1 ng cm À2 in Taozi Bay and 37.7 ng cm À2 in Sishili Bay, respectively.…”

“…The 5 cm depth burdens of DP were 8.5 ng cm À2 in Jiaozhou Bay, 20.1 ng cm À2 in Taozi Bay and 37.7 ng cm À2 in Sishili Bay, respectively. Sediment would store DP for a long time as one of the possible major sinks (Wang et al, 2010a, b). With a half-live of 14 years, DP is bioavailable for many aquatic organisms, and it might be harmful especially to the benthic biota (Ismail et al, 2009).…”

“…As a highly chlorinated flame retardant, DP has been used in plastic roofing material, hardware connectors for computers and for coating electrical wires and cables . The annual production of DP was reported to be 5000 tons, and it is sold in North America, Europe and Asia (Kang et al, 2010;Wang et al, 2010a). As a result of its wide application, DP has been detected in various environmental compartments, such as air, water, sediment, fish and human serum (Hoh et al, 2006;Tomy et al, 2007;Ren et al, 2009;Möller et al, 2010;Qi et al, 2010;Wang et al, 2010b).…”

“…15 Since then, many research studies have been carried out involving different environmental matrixes and biota samples. 16,17 Many studies have shown higher DP concentrations in air, 15,18−20 soil, 19 sediment, 21 and tree bark near manufacturing plants, 22 suggesting that commercial production may be an important pathway for DP to enter the environment. However, DP is considered highly lipophic, persistent, and bioaccumulative in the food chain.…”

Dechlorane Plus (DP), as a widely used flame retardant in different electrical and textile applications, has recently attracted great concern around the world. The present study investigated the DP levels and distribution in human samples from a DP manufacturing plant and a nearby area in east China. The DP concentrations ranged from 89.8 to 2958 ng/g lipid weight in whole blood and 4.08 to 2159 ng/g dry weight in hair. For the workers engaged in DP manufacturing process, their DP levels were significantly higher than those in most of the other two control groups from the nearby area. The values of anti-DP fractional abundance ( f anti ratio) were commonly lower in the human samples from both the manufacturing plant and nearby area compared with those in the commercial products, and excretion as well as biotransformation are possible reasons for stereoselective accumulation of the syn-DP isomer in humans. Furthermore, a significantly positive relationship (p < 0.05) was obtained between (i) the concentrations (and f anti ) in the paired blood and hair samples, indicating a similar distribution pattern of the two DP isomers in the paired samples; (ii) the DP levels in human body and the exposure time (p < 0.05), which suggests that further assessment could be needed to investigate potential long-term risks to the occupational population.

Dechlorane Plus (DP) is a high-production volume, chlorinated flame retardant comprising two major isomers, syn-and anti-DP. In this study, levels of DP were measured in soil and earthworm samples in farmland from a typical E-waste dismantling area in China. The concentrations of total DP ranged from 0.17 to 1,990 ng g -1 dw in soil samples and 3.43 to 89.2 ng g -1 lw in earthworm samples. Higher DP levels were found in some main E-waste dismantling sites than those in other sites. The ratios of anti-DP to total DP (f anti ) ranged from 0.57 to 0.80 in soil samples and 0.47 to 0.81 in earthworm samples, respectively. The f anti in most samples in this study was in the range of the reported technical DP values. These results showed that improper E-waste dismantling activities could result in the emission of DP. Most earthworm samples showed very low BSAFs (biota-to-soil accumulation factors) for total DP. The values of BSAF were in the range of 0.0007-1.85, with an average value of 0.23. This study presents the first report of the DP in earthworms, which would be useful for ecological risk assessment of DP in terrestrial ecosystem.
