The project starts during September 18th, 2013 and September 17, 2014. We select Changhua County in Central Taiwan Air Basin as the first research area in this project. The expected objectives have four-fold: (1) To understand the spatial differences of PM2.5 mass concentrations, (2) To understand the exposures of the residents, (3) To estimate the PM2.5 source apportionment, and (4) to establish the estimation model of PM2.5 mass concentration.
