| Summary: | 碩士 === 國立臺灣海洋大學 === 海洋環境資訊系 === 103 === From November 2014 to March 2015, 5 sets of size-fractionated aerosol samples were simultaneously collected from a coastal city (Keelung) and remote island (Pengjia). The aerosol samples were analyzed of non salt ions (nss), Carbon, Nitrogen, and Phosphorus species to disscus the influence of air mass sources on the Keelng and Pengjia. nss-Ca+2 and nss-K+ showed a statistically significant correlation at Pengjia, nss-SO4-2 showed a statistically significant correlation at Keelung. We also discussed NH4+/NO3- to compare two sites. NH4+ was major inorganic nitrogen during sampling period at Keelung. WSON had a weak correlation between two sites. Inorganic phosphorus in Pengjia was higher than in Keelug. In addition, the regression analysis of carbon showed a positive correlation, which represents a significant influence on WSOC in Pengjia. The results of correlation analysis showed statistically significant with anthropogenic and agricultural sources. The results of flux estimations indicated that Keelung was about 1.5 times higher than Pengjia for nitrogen, and Pengji was about 2 times higher than Keelung for carbon. In this study, we estimated the new primary production in the south of East China Sea, this would account for 11%~8% (Keeling) and 7.2%~6% (Pengjia).
