| Abstract: | Based on actual investigation and comprehensive analysis on the polluted degree caused by automobile tail gas on the main streets in Urumqi,the rule of pollution change about Co,NOx,TCH has been proposed in this paper. The daily average concentration of CO and NOx in the atmosphere at the central line on main urban streets has exceeded the secondary level of national atmospheric environment quality standards. According to the width of streets and the form of buildings, the urban streets were dcvidcd into three types. The polluted state caused by automobile tail gas in cach type were described. |
