Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds consisting of two or more fused aromatic rings and are probably one of the most studied groups of organic chemicals in environmental research. PAHs originate mainly from anthropogenic processes, particularly from incomplete combustion of organic fuels. PAHs are distributed widely in particulate matter. Due to widespread sources and persistent characteristics, PAHs disperse through atmospheric transport and exist almost everywhere. Human beings are exposed to PAH mixtures in gaseous or particulate phases in ambient air. Long-term exposure to high concentrations of PAHs is associated with adverse health problems. This review identifies the main research and development themes in the measurement and occurrences of PAHs in dusts and particulates using a new approach to carrying out a literature review where many peer-review publications have been produced. The review extracts the most important research themes from a literature search using a combination of text mining and a more detailed review of selected papers from within the identified themes.

多环芳烃（PAH）是由两个或多个稠合芳环组成的一组有机化合物，可能是环境研究中研究最多的有机化合物之一。PAHs主要来自人为过程，尤其是有机燃料的不完全燃烧。PAHs广泛分布于颗粒物质中。由于广泛的来源和持久的特性，多环芳烃通过大气传输而散布，几乎存在于所有地方。在环境空气中，人会暴露于气相或颗粒相的多环芳烃混合物中。长期暴露于高浓度的PAHs中会带来不利的健康问题。这篇综述使用一种新的方法进行了文献综述，确定了粉尘和颗粒中多环芳烃的测量和发生的主要研究和开发主题，其中已经出版了许多同行评审出版物。这篇综述结合了文本挖掘和从确定的主题中精选论文的更详细评论，从文献搜索中提取了最重要的研究主题。
