摘要
多环芳烃是一类广泛存在于各种环境介质中的持久性有机污染物。针对土壤中多环芳烃的污染现状,为了更加全面明确地识别污染源,进而能从源头上对多环芳烃的产生与排放加以控制,综合论述了国内外土壤中多环芳烃定性和定量源解析技术的研究进展;在介绍各种多环芳烃污染源解析模型的原理和特点的同时,通过对比国内外相关研究的实例说明各解析方法的使用前提和适用范围,讨论了源解析技术进步对污染物控制、治理的意义和重要性;并对土壤中多环芳烃源解析技术研究未来的发展趋势作出展望,为区域环境治理和能源利用结构调整等相关决策地制定提供参考依据。
Polycyclic aromatic hydrocarbons(PAHs)are persistent organic pollutants that widely exist in various natural environmental medium.For the status of PAH-contaminated soil,in this paper a variety of qualitative and quantitative soil PAHs source apportionment models were reviewed in order to identify sources of pollution and control the emission of PAHs more accurately.The principles and methods of the qualitative and quantitative models were illustrated,and the application and the scope of the analytic methods were explained by comparing the examples at home and abroad.The significance and importance of source resolution technology to pollutant control and treatment were discussed;at the same time,the principles and characteristics of various analytic models of PAHs pollution sources were introduced.Finally,the development prospects in the future in the study of PAHs source apportionment were also put forward,so as to provide theoretical references for protecting environmental safety and adjusting the local energy structure.
