Abstract：
:Polybrominated diphenyl ethers (PBDEs, tri-to hepta-BDEs) and Dechlorane Plus (DP) in multiple samples (soil, sediment, road dust, and PM2.5 particles) in historical locations of our previous work in Guiyu (electronic-waste recycling town) in southeastern China were investigated in 2014. Ten years later, PBDEs and DP were detected in 100% of the samples. Ʃ3-7PBDEs were still relatively great, ranging from 1.2 × 101 to 2.1 × 103 ng/g dry weight (dw) in soil, 2.1 to 3.2 × 103 ng/g dw in sediment, 1.0 × 101 to 1.1 × 104 ng/g dw in road dust, which were a little less than or close to those measured in 2004. However, Ʃ3-7PBDEs in PM2.5 (5.0 × 102 to 8.4 × 102 pg/m3) were significantly lower in 2014. BDE-47, -99, -153, and -183 were predominant congeners, which were also predominant PBDEs reported in Guiyu (2006-2008). Greater proportions of lesser-brominated BDEs were predominant in PM2.5 than other samples. DP was detected in 100% of the samples collected with high levels. Total syn-DP and anti-DP concentrations were 3.8 to 2.1 × 103 ng/g dw in soil, 1.1 × 103 to 7.2 × 103 ng/g dw in sediment, 1.4 × 101 to 1.1 × 103 ng/g dw in road dust, and 1.8 × 102 and 1.7 × 102 pg/m3 in PM2.5. Most of the fractions of anti-DP (fanti) (70%-80%) were consistent among samples. The health risk assessment showed that hazard indexes (HIs) of PBDEs or DPs for child or adult were all lower than 0.16.
