- Abstract
Many researches have been conducted on the health influence of Particle Matter with diameters less than 2.5 microns (PM $$_{2.5}$$ ). There are also some researches on the cause of PM $$_{2.5}$$ . However, such research generally focuses on the economic and political aspect of the environment issue. In this paper, a data-analysis approach of the PM $$_{2.5}$$ issue is raised to offer a new viewpoint of this problem. The applied method extracts the relations of air quality system record as a relation map, which illustrates the influence among the parameters in a graph. The method successfully fitted the weather record, and derived from it the influencers of PM $$_{2.5}$$ . The result shows that the average temperature, average barometric pressure and concentration of Ozone are all factors that have an influence on the concentration of PM $$_{2.5}.$$ A short justification of it is also provided.
