Ambient fine particulate matter with diameter less than 2.5 mu m (PM2.5) is a cause for concern largely due to its negative impact on human health. This study evaluated the research on PM2.5 using a bibliometric analysis of published research from 1999 to 2014 based on the Science Citation Index (SCI) database. We presented the publication indicators in PM2.5 research, evaluated the research performance of countries and institutes and analyzed the research trends and hot topics by statistics of keywords. The annual number of research outputs grew from 118 in 1999 to 1262 in 2014, although there was a decline from 2008 to 2010. The USA contributed the most publications (36.0%), with the US EPA, the Chinese Academy of Science and Harvard University being the most productive institutes. We also listed the top journals that published the most articles on PM2.5 and the articles cited the most in top20. Keywords analyses showed that the chemical composition, source apportionment and health effects of PM2.5 are the most popular topics in PM2.5 research, followed by size distribution, pollutant diffusion and GIS techniques in the spatial simulation of PM2.5 concentration. We also carried out national and temporal analyses of keywords. We further analyzed the emphasis and trends with respect to the popular topics and listed typical research results from across the world.
