The serious air fine particles pollution and obvious secondary pollutant characteristics in Chengdu were determined, through synchronously continuous sampling and monitoring activities for three types of particles defined by size in summer and winter respectively. Through qualitative analysis such as multiple regression analysis, enrichment factor analysis, and chemical constituent factor analysis for chemical composition and source of pollutants, it was demonstrated that the inhalational particles mainly originated from the combustion of fossil material and oil, biogenic material, cooking industry emission, building industry emission or metallurgic emission, etc.
