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.
