碩士 / 弘光科技大學 / 環境工程研究所 / 93 / The experiments of this study were carried out at Taichung between August 2003 and January 2005. The long-term concentration of the ambient particulate mass were measured at Chung-Chi Road (CCR; Site-I, traffic), Wu Chi Elementary School (WT; Site-II, traffic), and Tacihung Harbor (TH; Site-III, Harbor) sampling sites. During this air sampling period, Dry Deposition Plate, TE-PUF Air Sample, and Universal Air Sample were used to collect the ambient suspended particles for various size ranges. In addition, the samples collected were analyzed by a Ion Chromatography for the ionic species (Cl-, SO42-, NO3-, NH4+, Na+, K+, Ca2+, and Mg2+) analysis. The dominant ionic species for TSP are SO42-, NO3-, and NH4+ of the total mass of the inorganic ions at sampling sites. In addition, the results indicated that the NH4 +, NO3 - and SO4 2- showed higher concentrations in winter, and lower in summer for both TH and WT sampling site. Statistical methods such as correlation coefficient and principal component analysis were also used to identify the possible pollutant source in the study. Principal component analysis indicated that the soil, secondary aerosols and marine salt source were the possible major pollutant source at the Taichung Harbor sampling site. As for the WT and CCR (traffic) sampling site, secondary aerosols and atmospheric reactions were the dominant factors responsible for this result.
