摘要
利用降水自动监测仪和空气自动监测系统的同步监测结果,分析了一次34 5mm连续降水中全过程的pH、EC和同期SO2、PM10、NO2的变化情况。降水中pH值为7 23~4 08、EC为488 8~7 6μS cm,pH、EC在降水初期变化较大。pH与EC、SO2呈现负相关趋势,降水过程中PM10、NO2基本保持较低水平,SO2变化较大。
According to the data from rain automatic monitors and air auto-monitors,we analyze the change of values of pH, EC, SO2, PM(10), NO2 in a continuous rainfall. The pH value is from 4.08 to 7.23 and EC value is from 7.6 to 488.8μS/cm. The values of pH and EC have great change at the beginning of the rain . The values of pH and EC show negative correlation. The values of PM(10), and NO2 keep low level in the procedure of the rain, The SO2 values have great change.
