碩士 / 國立臺灣海洋大學 / 海洋環境資訊系 / 103 / We analyzed 53 aerosol samples, collected from July to December 2013 on the southern East China Sea at Pengchiayu Island, Taiwan. The aerosol samples were analyzed for water-soluble major ions, carbon, nitrogen, and phosphorus species. In addition, 4-d back trajectories of air masses arriving saily at the sampling site were calculated to determine thr potential aerosol source regions. The obtained concentrations of major ions indicate that a continental source was dominant from January to May and from November to December, a local source during July, and an oceanic source from Septmber to October. The measured atmospheric concentrations of carbon, nitrogen and phosphorus species show clear seasomal variations and correspond to the different sources and weather conditions. Natural and anthropogenic land sources and marine sources are the most influential factor in term of the distribution of aerosol during the dust storm period. Consequently, the inputs of aerosol derived from biomass buring may be an important source of carbon, nitrogen, and phosphorus in aerosols over the East China Sea.
