“…As shown in Figure 2, good linear relationships were observed for QY (R 2 ¼ 0.77, p < 0.00001) and GY (R 2 ¼ 0.65, p < 0.0001), suggesting that the PBDE concentrations in the soils from areas surrounding e-waste facilities mainly came from the e-waste recycling sites via air transport. These results were consistent with those of our previous study of dechlorane plus in these areas [25].…”

Abstract-Polybrominated diphenyl ethers (PBDEs) were determined in 60 surface soils from two e-waste recycling sites (Qingyuan and Guiyu, China) and their surrounding areas to assess the extent and influence of PBDEs from e-waste recycling sites on the surrounding areas. A total of 32 surface soils from industrial areas in South China were also investigated for comparison. The mean concentrations of total PBDEs in the e-waste recycling sites of Guiyu and Qingyuan were 2,909 and 3,230 ng/g dry weight, respectively, whereas the PBDE concentrations decreased dramatically (1-2 orders of magnitude) with increasing distance from the recycling site, suggesting that the e-waste recycling activities were the major source of PBDEs in the surrounding areas. Decabromodiphenyl ethers accounted for 77.0 to 85.8% of total PBDEs in e-waste recycling areas, whereas it accounted for 90.2% in industrial areas. Principal component analysis showed that the major source of PBDEs in e-waste recycling areas were a combination of penta-, octa-, and deca-BDE commercial formulations, whereas deca-BDE commercial formulations were the major source of PBDE congeners in industrial areas. The inventories of PBDEs gave preliminary estimates of 6.22 tons and 13.4 tons for the e-waste recycling areas and industrial areas. The results suggested that significantly higher PBDEs in the e-waste recycling sites have already affected surrounding areas negatively within a relatively large distance.

“…Recycling of e-wastes could release particles loaded with heavy metals and flame retardants into the atmosphere and adjacent environmental compartments. In typical ewaste dismantling areas, e.g., Guiyu and Qingyuan in South China, where informal e-waste recycling activity was prevalent several years ago, DP concentration was 3327 ng g − 1 dw in soil from the e-waste recycling site (Yu et al, 2010). The levels fell dramatically with increasing distance away from the site, suggesting an evident influence of ewaste dismantling activities to the surrounding environment (Yu et al, 2010).…”

The levels fell dramatically with increasing distance away from the site, suggesting an evident influence of ewaste dismantling activities to the surrounding environment (Yu et al, 2010). In a reservoir in the vicinity of e-waste recycling workshops in South China, DP was detected in all the aquatic species (e.g., water snake, mud carp, crucian carp, northern snakehead, prawn and Chinese mysterysnail) with concentrations of 19.1-9630 ng g −1 lw, which were much higher than those in the reference mud carp (syn-DP: 1.35 ± 1.35 ng g −1 lw; anti-DP: 7.41 ± 7.32 ng g −1 lw) (Wu et al, 2010).…”

Although Dechlorane Plus (DP) has been used as a polychlorinated flame retardant for almost half a century, its detection in the environment was not reported until 2006. The subsequent intensive research has confirmed its global ubiquity. A few reviews have presented the properties, analytical methods and environmental occurrence of DP and related compounds in the past several years. The present review emphasizes on the environmental behavior of DP isomers which is assessed by the variation of the isomer ratio of DP in various matrices. Other aspects including the analytical methods, emission sources, general environmental occurrence and bioaccumulation of DP are also summarized. In this review, three typical emission sources in the environment are categorized after introducing the measurement method of DP. The temporal-spatial distribution is then evaluated at the global scale, which provides an integrated representation of the environmental occurrence of DP and potential impact on the human health and ecosystems. The variations of DP isomer ratio in various matrices reinforce its source related distribution and their stereoselective bioaccumulation. Thereafter, DP related compounds and dechlorinated analogs are briefly summarized in regards to their occurrence in various matrices, suggesting their ubiquity in the environment and bioavailability. Further studies are required to better assess the exposures and toxicological effects of DP and its analogs. A special concern is the serious contamination in e-waste recycling areas in developing countries, where long-term monitoring data on the association of DP exposure and adverse effects to human health and ecosystems is urgently needed.

“…Besides domestic usage, the import of DP or DP containing products (including e-waste) from overseas could also elevate the levels in the Chinese environment. Yu et al (2010) found that in an e-waste recycling site in Qingyuan, the concentration of DP reached up to 3327 ng g À1 dw in surface soil.…”
