| Abstract: | The mean concentration data of SO2.NO2 and PM10 of environmental monitoring sites were analyzed statistically in Hohhot city from 2006 to 2009. The results showed that daily mean concentration of S02 is between 0.017 and 0.188mg·m^-3, the superstandard rate is 4.0%, daily mean concentration of NO2 is between 0.026 and 0.081mg·m^-3, isn＇t more than national secondary standard, daily mean concentration of PM10 is between 0.036 and 0.332mg·m^-3, the superstandard rate is 6.5%, the pollutant concentration of June and August are minimum, January and December are maximum , the pollutant concentration of Hohhot showed a decreasing tendency in general in recent years. |
