AB  - The temporal trends of polychlorinated biphenyls (PCBs), polychlorinated 
      dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polybrominated diphenyl ethers 
      (PBDEs) were investigated in soils from an E-waste dismantling area in East China 
      between 2005 and 2011. Isotope dilution high resolution gas chromatography/high 
      resolution mass spectrometry (HRGC/HRMS) was employed for the sample analysis. 
      PCB levels declined as expected, while PCDD/Fs generally remained at a constant 
      level during the sampling period, and PBDE concentrations tended to be slightly 
      lower after 2007 although the decline was not statistically significant. The 
      congener profiles indicated that lowly-halogenated congeners of these persistent 
      organic pollutants (POPs) accounted for the decreasing levels and relative 
      proportions of the POPs, suggesting that they have been gradually eliminated from 
      the field soil over the years. However, the concentration levels of some heavy 
      congeners (e.g., CB-209, OCDD and OCDF) showed different trends from those of the 
      lighter ones. The general tendencies of the three types of POPs in soils were 
      consistent with those reported in other studies in this area. The results implied 
      that the enhanced regulations and centralized dismantling action introduced in 
      2005 might exert a limited influence on these three types of POPs in soils during 
      the sampling period.
