Feasibility Analysis of a Method for Physical Source Apportionment of PM2.5 Based on Particle Morphology and Size Distribution

Abstract:

Inhalable particles do harm to the environment and health, especially fine particles, also as PM2.5. PM2.5 is the key pollutant of the compound air pollution, and becomes the primary indicator of the urban air pollution. Source apportionment to track the source of the particulate matter is important to the evaluation of the effect of pollution sources on environment and health. It can also provide scientific evidence for the prevention and control of air pollution. Methods of chemical source apportionment have been accurate and developed based on the assumption of linear combination of receptor model with much mathematical computing and complex operations. The physical characteristics such as morphology and size distribution of particulates from different sources are significantly different. We could establish data base of physical properties about atmospheric particulates, and develop a new physical method of source apportionment used in quantitative analysis.
