Gas emission of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) from 19 commercial municipal solid waste (MSW) incinerators in China are investigated. The emission concentrations of PCDD/Fs were 0.042-2.461 ng TEQ Nm(-3) with an average value of 0.423 ng TEQ Nm(-3). The emissions of PCDD/Fs from 16 MSW incinerators were below the MEP regulation level (1.0 ng I-TEQ Nm(-3)), while only six systems have the dioxin emission levels below the limit established by the European Union Directive of 0.1 ng I-TEQ Nm(-3). The emission factors of PCDD/Fs from 19 MSW incinerators were calculated to be 0.169-10.72 microg TEQ ton(-1) MSW with an average value of 1.728 microg I-TEQ ton(-1) MSW. The total amount of PCDD/Fs emitted from MSW incinerators to the atmosphere in China was estimated to 19.64 g TEQ year(-1) in 2006.
对中国19座商业城市生活垃圾焚烧炉中多氯代二苯并 - 对二噁英和多氯代二苯并呋喃（PCDD/Fs）的气体排放情况进行了调查。PCDD/Fs的排放浓度为0.042 - 2.461 ng TEQ Nm(-3)，平均值为0.423 ng TEQ Nm(-3)。16座城市生活垃圾焚烧炉的PCDD/Fs排放低于环保部的规定水平（1.0 ng I - TEQ Nm(-3)），而只有6个系统的二噁英排放水平低于欧盟指令规定的0.1 ng I - TEQ Nm(-3)的限值。19座城市生活垃圾焚烧炉的PCDD/Fs排放因子经计算为0.169 - 10.72 μg TEQ ton(-1) 城市生活垃圾，平均值为1.728 μg I - TEQ ton(-1) 城市生活垃圾。据估计，2006年中国城市生活垃圾焚烧炉向大气排放的PCDD/Fs总量为19.64 g TEQ year(-1)。
