中文摘要 | 於八十九年度之雨季,在屏東市、內埔、潮州、鹽埔及萬巒等五處設定雨水收集站,共收集128個樣品。樣品經測定pH值後過濾再以離子層析儀測定陰、陽離子之含量,數據分析後得知:去年度雨水中酸度之主要物種為硫酸鹽類,再由與pH值相關性比較後知硫酸並非是硫酸鹽類的唯一來源;同屬較內地的鹽埔及萬巒兩地[Na⁺]/[Cl¯]比值要較其他三處高,推之內地空氣污染物之主要來源不同於迎季風處。濕沉降化學特性之探討,可有效地應用於空氣品質監測上,若能累積多年的數據,必能對空氣污染控制工作上提供具體的參考資訊。 |
英文摘要 | This study investigated the chemical characteristics of rain water based on 128 samples collected from sample stations set in 5 regions including Pingtung City, Nei-Pu, Wan-Luan, Chao-Chou, and Yen-Pu. The pH of samples were tested, and then filtered and analyzed for the indicators of the presence of acidification (such as sulfate, nitrate and other cation concentrations) using ion chromatography. Results of this study showed that sulfate is the major pollutant at present affecting the chemical characteristics of wet deposition in these five regions. However, sulfate is not the only contributing factor to the acid rain. The data also illustrated that in hinterlands, such as Yen-Pu and Wan-Luan, have higher [Na⁺]/[C⁻] ratio might be due to the major air pollutants in these two areas are different than those three other regions. The assessment of the characteristics of wet deposition in these regions can provide more information in air pollution control strategies in the future. |
