摘要
考察表明四面山是大气清洁背景区;四面山低空大气降水、雾露、等未见酸化,污染较轻;高空大气降水、雨、雪等已酸化,污染较重。四面山大气降水的酸化主要不是云下形成的,即当地源对降水污染不起主要作用,区内存在着酸沉降母质由城区向背景区的输送。
The results of observation show the concentration of SO<sub>2</sub> and the co-mponents in fog and dew are relatively low.The ones in rain and snow are high.Thedifferences show precipitation from high altited has been polluted and ones from theiow has not suggesting sulfur pollution of precipitation at Fourside Mountain is not cau-sed by washout below cloud,and the urban area has influenced on the suburban and-rural sites.
