英文摘要	Atmospheric concentrations of Dechlorane Plus (DP) were investigated in Taizhou, an electronic-waste (E-waste) dismantling region in East China. Passive air samplers with polyurethane foam (PUF) disks were deployed every three months during the sampling period of September 2009-August 2010. The total DP (syn- and anti-DP) concentrations in air ranged from not detected to 277 pg/m(3), with a mean concentration of 53.9 pg/m(3). A generally declining trend of DP levels was found from the E-waste dismantling region to the peripheral areas. The median values of total DP concentrations in autumn, winter, spring and summer were 52.2, 28.8, 39.7 and 30.1 pg/m(3), respectively. The seasonal variations of DP concentrations were mainly associated with the intensity of E-waste dismantling activities and meteorological conditions. The mean value of anti-DP fractional abundance (f (anti)) was 0.74 +/- 0.08, which was consistent with those in the commercial DP products. This study confirmed a significant emission source related to the distribution of atmospheric DP in the E-waste dismantling area and supplied information for the seasonal variation of DP in the atmosphere.
