Simulation of PM2.5 Particulate Matter Pollution in US East Coast Using SMAT-CE Software

Abstract

Nowadays air pollution is becoming a serious global threat to human health and environment. Particulate matter with size of 2.5 micron or less are much more harmful for health because they can be easily absorbed into deep part of the lung. In order to control PM2.5 air pollution, it is important to understand the PM2.5 pollution diffusion mechanism and find out the factors affecting its propagation. In this poster, we use SMAT-CE software by US EPA and TIBCO to simulate the PM2.5 air pollution in US east coast. The data of PM2.5 pollution levels were collected by EPA and available in its website. Through SMAT-CE simulation, we plot the heat map of PM2.5 concentrations of major cities in US east coast in the past years. Based on the data, we tried to find its relation to various weather conditions, wind and other factors. The results will be helpful to further understand the behavior of PM2.5 air pollution and suggest some possible ways to improve the air quality in the area.
