为获知呼和浩特市交通要道氮氧化物（ NOX）污染现状，采用短期暴露扩散采样法，于2010年3月21至4月24日，在呼和浩特市区交通要道设置四个采样点，对氮氧化物进行了监测并分析。实验结果为四个采样点的NOX浓度日平均值为0．012～0．14mg· m-3，表明呼和浩特市交通要道附近氮氧化物浓度存在超标现象，有关职能部门应采取有效措施，防治NOX污染的发生。

In order to learn the present situation of nitrogen oxide compound ( NOX) pollution of key communication line in Hohhot , four sampling points were established in key communication line in Hohhot to monitor and analyze the nitrogen oxide compound on March 21 to April 24,in 2010, using the short-term exposition diffusion sampling method .The results was that the mean value of the density of NOX of the four sampling point NOX is 0.012~0.14mg· m-3 daily ,which indicated that the phenomenon of exceeding the allowed figure of the density of NOX of the key communication line nearby the Hohhot existed and the related functional departments should take the effective ac -tion to prevent and control the occurrence of the NOX pollution .
