Fine particulate matter (PM) is one of the major air pollutants. A large number of epidemiological and experimental studies have shown that PM pollution can cause adverse health consequences, which has attracted more public attention. In order to have a deeper and more structured understanding of the research progress and frontiers on the impact of PM on health, in this study, we used the bibliometrics software CiteSpace to analyze the relevant literature in this field. The results show that since 2000, the relevant literature has increased steadily, especially in the last 5 years, and the number of publications in China has increased rapidly. The United States has the most publications. The Chinese Academy of Sciences and Professor Joel Schwartz are the most published institution and author, respectively, and many articles have been published in the journal of Environmental Health Perspectives. Over time, studies on the health effects of PM have gradually deepened. In addition to a more comprehensive study of its harmful effects, the related molecular mechanisms have also been further explored. We believe that countries and regions should strengthen cooperation and jointly solve the harm caused by PM through the integration of multiple disciplines and fields. In addition, the adverse health consequences and its related mechanisms caused by exposure to ultrafine particle, different chemical components of PM, as well as the intervention of the health effects caused by PM need to be further studied.
细颗粒物（PM）是主要的空气污染物之一。大量的流行病学和实验研究表明，PM污染会导致不良健康后果，这引起了公众更多的关注。为了更深入、更系统地了解PM对健康影响的研究进展和前沿，在本研究中，我们使用文献计量学软件CiteSpace分析该领域的相关文献。结果表明，自2000年以来，相关文献稳步增加，尤其是在过去5年，中国的发文量增长迅速。美国的发文量最多。中国科学院和乔尔·施瓦茨教授分别是发文最多的机构和作者，许多文章发表在《环境健康展望》杂志上。随着时间的推移，对PM健康影响的研究逐渐深入。除了对其有害影响进行更全面的研究外，相关分子机制也得到了进一步探索。我们认为，各国和各地区应加强合作，通过多学科和多领域的整合共同解决PM造成的危害。此外，暴露于超细颗粒物、PM的不同化学成分以及PM对健康影响的干预所导致的不良健康后果及其相关机制仍需进一步研究。
