Measurement and analysis of ambient air particulates and ionic species for composition and concentration studies at the western coast of central Taiwan.
Air-polluting aerosol samples consisting of total suspended particulates, coarse particulates (>2.5 approximately 10 microm in diameter), fine particulates (<2.5 microm in diameter), and ionic species were collected from March 2004 to January 2005 at the western coast of central Taiwan. Statistical methods such as nonparametric test and T statistical analysis were also employed to distinguish the variation difference for pollutants among four seasons in this study. Seasonal variation of ionic species SO4(2-) in the total suspended particulates and fine particulates shows that higher composition was observed among four seasons. The results of T statistical analysis revealed that the concentrations of ionic species NO3- showed no significant changes in coarse and fine particulates among the four seasons. In addition, the results also revealed that the concentrations of ionic species Na+ showed no significant changes in coarse and fine particulates in the seasons of spring and autumn at the western coast of central Taiwan.
