| Abstract: | Dissolved chemical compositions in rainwater have provided valuable information on pollutant sources in the atmosphere and short-term environmental changes. However, baseline chemical data associated with typhoon is rather limited. In this study, a suite of time-series rain specimens including four typhoon events are collected from Tainan city, southern Taiwan and analyzed for major ions, heavy metals and Pb isotopes to elucidate mechanisms causing dissolved components variation in rainwater and to understand how heavy metals are transported by air-mass along typhoon pathways. |
