Particulate matter (PM) has become one of the most serious causes of premature death in the world. A variety of diseases of respiratory system

cardiovascular system is directly related to PM. In recent years

China's environmental pollution has become more and more serious. PM2.5 was one of the main pollution sources;therefore

it is significant to study effective interventions on potential health problem caused by PM2.5. In this paper

the distribution of research teams

research units

research fields and research hotspots concerning domestic atmospheric particulates from 2003 to 2013 were studied by using the literature metrology

association rules mining and clustering analysis methods. This could provide reference information and trends about PM2.5 to researchers especially medical researchers.
