摘要： 垃圾填埋是城市生活垃圾处理的一种主要方式，垃圾焚烧发电正在逐步取代垃圾填埋。然而，焚烧过程中持续性有机污染物多氯二苯并二噁英和二苯并呋喃(二噁英)的排放问题引起了社会的广泛关注。基于高分辨气相色谱质谱联用技术(HRGC-MS)的二噁英离线检测方法具有价格高昂、检测频率低和检测结果滞后等不足，而利用指示物来实现二噁英的快速间接测量则是一种非常有前景的方法。本文讨论了六类潜在的二噁英指示物:一氧化碳、总碳氢化合物、特定的二噁英同系物、多环芳烃、氯酚和氯苯。并基于以下四个标准：分子结构相似性、已探明的生成机理、文献中的相关性系数和易检测性，对这些指示物的表现进行了系统的评估和验证。综合考虑四个指标，氯苯可能是最适合的二噁英检测指示物。基于光子电离耦合飞行时间质谱的分析方法（PI-TOFMS）已经被证明是一种有效的二噁英指示物在线检测技术，检测结果可以用于垃圾焚烧过程所排放二噁英毒性当量的预测。此外，对于成分复杂、浓度较低的样品，可以在PI-TOFMS的基础上增加热解析和气相色谱的步骤，对样品进行额外的分离和浓缩，从而提升检测精度。

Abstract: Landfilling, a traditional and major method for municipal solid waste management, is gradually being taken place by incineration. However, the contamination problem caused by polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) emissions from incineration has also brought much concerns. Traditional offline method based on high-resolution gas chromatography coupled with high-resolution mass spectrometry for the determination of PCDD/F emissions is expensive, infrequent and time-lagging. Use of PCDD/F indicators to achieve fast indirect measurements for PCDD/Fs is a much more promising method. Six categories of potential PCDD/F indicators are discussed in this paper: CO, total hydrocarbons, specific PCDD/F congeners, polycyclic aromatic hydrocarbons, chlorophenols and chlorobenzenes. Their performance as PCDD/F indicators are verified in the following criteria: (1) structural similarities; (2) known mechanistic arguments; (3) known correlation values from the literature and (4) detectability. Comprehensively considering the four factors, chlorobenzenes may be the best suitable PCDD/F indicator. One analytical method based on Photon Ionization coupled with Time-of-Flight Mass Spectrometry has been proved effective for the online/atline measurements for PCDD/F indicators for the prediction of TEQ in incineration process. Moreover, thermal desorption and gas chromatography can be applied to provide extra separation and concentration for very complex matrices with extremely low concentrations.
