摘要
根据交通干线空气质量自动监测站氮氧化物(NOX、NO2、NO)和车流量数据以及大型节假日(春节)前后的对比情况等观测结果,针对性地讨论了重庆地区区域环境内机动车尾气排放源中氮氧化物的污染水平,以及对市区域环境空气质量的影响。
According to the monitoring data of nitrogen oxides （NOx, NO2, NO） from the traffic automatic air quality monitoring station, the air contamination level of nitrogen oxides emitted from the vehicles along the road was analyzed. The changes of the level were compared before and after the important holiday like Chinese new day considering the changes of vehicle flowrate. The impacts of nitrogen oxides on the regional air quality were presen- ted as well.
