| 摘 要： | 分别在成都市市区和郊区采集冬季辐射雾雾水样品,pH值范围在4.58—6.39之间,平均值为5.57.离子色谱分析其无机阴离子(SO42-,NO3-,Cl-)浓度水平.结果显示,雾水中的阴离子以SO42-浓度最高(3.11mg.l-1),NO3-(0.20mg.l-1)和Cl-(0.25mg.l-1)相对较低;雾生消过程中市区和郊区雾水样品阴离子的变化规律及分布特征有显著差异.雾水中的阴离子浓度普遍低于此期间的降水.

| Abstract: | Two sampling sites were chosen to study concentrations and variations of anions during winter radiation fogs in Cbengdu city and its suburb area.Anions were measured by ion chromatogram.Results showed that pH values of the fog water were between 4.58 and 6.39,exhibiting acidity and the average concentration of SO_4(~2-) was 3.11 mg·l~(-1),much higher than that of NO_3~- and Cl~-(0.20 and 0.25mg·l~(-1)).Variation of the concentration of anions in genesis and dissipation of fog between urban and suburban area showed obvious difference.Concentrations of anions in fog water were substantially lower than in the rain. |
