摘　　要：1988年冬季,我们对云南省安宁工业区和西双版纳非工业区雾水进行采集,工业区雾水混浊肮脏,含有大量固体颗粒,雾水中离子浓度值与附近工厂排向大气的污染物有关,但雾水酸度值并不高。非工业区雾水比较清洁,雾水中离子浓度值平均比工业区低一个数量级。本文还讨论了一个雾过程离子浓度变化与温度层结的关系。The author collected fogwater samples in the industrial district of anning and the non-industrial district of Xishuangbanna in the winter of 1988 in Yunnan. The amount of each sample was 10-15ml. The acidity and ions concentration in fogwater were detected. In the industrial district, the fogwater was turbid and opaque, and a lot of solid corpuscule could be found after filtrated, the ions concentration of fogwater is concerned in atmosphere pollutants which are exhausted by local scale factories. The acidity of fogwater in the industrial district was relatively low and its pH value ranged from 5.4 to 7.5. The fogwater is transparent in non-industrial district. The ions concentration except No2 in non-industrial district was one magnitude lower than that in industrial district. Finally, the authors discussed the relationship between ions concentration of fogwater in a fog event and the temperature profile of fog.
