Polychlorinated diebenzo-p-dioxins (PCDD ) ， polychlorinated diebenzofurans (PCDF ) ， polychlorinated (印刷电路板) 和 polybrominated diphenyl (PBDE ) 在 Taizhou，拆除东南中国的区域评估他们的集中的电子浪费，侧面并且煤气粒子的划分的周围的空中被监视。三角洲 PCDD/Fs 集中从 2.91 ～ 50.6 pg/m (3 )，与 14.3 pg/m (3 ) 的一般水准。为 PCDD/Fs 的 I-TEQs 在 0.20-3.45 pg/m (3 ) 的范围，与 1.10 pg/m (3 ) 的一般水准。西格马印刷电路板集中和 TEQ 从 4.23 ～ 11.35 ng/m (3 )， 0.050 ～ 0.859 pg (TEQ )/m (3 ) 分别地。西格马 PBDE 的集中从 92 ～ 3086 pg/m (3 )，与 894 pg/m (3 ) 的一般水准。PCDD/Fs，印刷电路板和 PBDE 的污染层次比另外的城市的地点高，它可以与拆除活动的电子浪费被联系。而印刷电路板在煤气的阶段主导地散布了， PCDD/Fs 专门在粒子阶段被发现。划分也是的 gas-partilce 与使过冷的液体蒸汽压力(P-L (0 )) 由相关估计了煤气粒子的分配系数(K-p ) 。PCDD/Fs，印刷电路板和 PBDE 的测量微粒吸着与从 Junge-Pankow 模型和洋槐的一种吸收模型的预言相比。Junge-Pankow 模型很好估计了印刷电路板的微粒部分。然而，它低估了 PCDD/Fs 的吸着并且过高估计 PBDE 的部分。从与测量数据适合很好的洋槐的一种模型的 PCDD/Fs 和印刷电路板的预言的微粒部分。

英文摘要：

Polychlorinated diebenzo-p-dioxins （PCDDs）, polychlorinated diebenzofurans （PCDFs）, polychlorinated biphenyls （PCBs） and polybrominated diphenyl ethers （PBDEs） were monitored in the ambient air of Taizhou, an E-waste dismantling area of southeast China to evaluate their concentrations, profiles and gas-particle partitioning. The ∑PCDD/Fs concentrations ranged from 2.91 to 50.6 pg/ma, with an average of 14.3 pg/ma. The I-TEQs for PCDD/Fs were in the range of 0.20-3.45 pg/ma, with an average of 1.10 pg/ma, The ∑PCBs concentrations and TEQs ranged from 4.23 to 11.35 ng/ma, 0.050 to 0.859 pg（TEQ）/ma, respectively. The concentrations of ∑PBDEs ranged from 92 to 3086 pg/ma, with an average of 894 pg/ma, The pollution levels of PCDD/Fs, PCBs and PBDEs were higher than other urban sites, which may be associated with the E-waste dismantling activities. The PCDD/Fs were found exclusively in the particle phase whereas PCBs distributed dominantly in the gas phase. The gas-partilce partitioning was also assessed by correlating the gas-particle partition coefficient （Kp） with the subcooled liquid vapor pressure （pL^0）. The measured particulate sorptions of PCDD/Fs, PCBs and PBDEs were compared with the predictions from Junge-Pankow model and Koa absorption model. The Junge-Pankow model well estimated the particulate fractions of PCBs. However, it underestimated the sorptions of PCDD/Fs and overestimated the fractions of PBDEs. The predicted particulate fractions of PCDD/Fs and PCBs from Koa model fitted well with the measured data.
