Source apportionments have become increasingly performed to determine the origins of ambient particulate pollution. The results can be helpful in designing mitigation strategies to improve air quality. Source specific particulate matter (PM) concentrations are also being used in health effects studies to be able to focus attention on those sources most likely to be responsible for the observed adverse health effects. In 2015, the World Health Organization (WHO) released its initial compilation of source apportionment studies published through August 2014. This initial database was described by Karagulian et al. (Atmospheric Environment120 (2015) 475-483). In the present report, a new compilation has been prepared of those apportionments published since 2014 through December 2019. In addition, the database has been expanded to include apportionments of heavy metals, water-soluble components, and carbonaceous components in ambient PM. As a result of this work, we have developed and presented some perspectives on source apportionment going forward. We also have made a series of recommendations for source apportionment studies and reporting them. It is essential for papers to provide a minimum set of information so that the study can be adequately assessed, and the results utilized by others in making policy decisions or as part of other scientific studies.
源解析已越来越多地用于确定环境颗粒物污染的来源。这些结果有助于设计缓解策略以改善空气质量。特定来源的颗粒物 (PM) 浓度也用于健康影响研究中，以便能够关注那些最有可能导致观察到的不良健康影响的来源。2015 年，世界卫生组织 (WHO) 发布了其截至 2014 年 8 月发布的源解析研究的初步汇编。Karagulian 等人对这个初始数据库进行了描述 (Atmospheric Environment120 (2015) 475-483)。在本报告中，我们根据 2014 年至 2019 年 12 月发表的研究，对这些分配情况进行了新的汇编。此外，该数据库已扩展到包括环境 PM 中重金属、水溶性成分和含碳成分的分配情况。通过这项工作，我们对未来的源解析工作提出了一些看法。我们还针对源解析研究及其报告提出了一系列建议。为了使研究能够得到充分评估，并且研究结果能够被其他人用于决策或作为其他科学研究的一部分，论文提供一套最低限度的信息是至关重要的。
