| 摘 要： | 于秋冬两季，利用法国生产的自动监测仪对重庆市城区7条交通主干道的近地面空气质量进行了监测。结果表明：在监测期间，各个监测点PM1o是首要污染物，并且秋季比冬季污染严重，7条道路的日平均浓度为0．419mg／m^3，最大浓度为0．687mg／m^3，最大超标率为3．58倍；而NO2和SO2在冬季比秋季污染严重，NO2最高浓度是0.126mg／m^3，平均浓度是0．089mg／m^3，S02最高浓度是0．333mg／m^3，平均浓度是0．216mg／m^3，表明交通干道空气污染严重。 |

| Abstract: | In autumn and winter,the near ground air quality of seven traffic main roads were monitored by automatic instruments made in France. The results indicated that PM_(10) was the chief pollutant in the period,and PM_(10) pollution is more serious in autumn than in winter,daily average concentration was 0.419 mg/m~3 in seven roads,the maximum concentration was 0.687 mg/m~3,the maximum exceeding rate was 3.58 times;NO_2 and SO_2 are more serious in winter than in autumn ,the maximum concentration of NO_2 is 0.126 mg/m~3,daily average concentration was 0.089 mg/m~3 ,the maximum concentration of SO_2 was 0.333 mg/m~3,daily (average) concentration was 0.216 mg/m~3 in seven roads.It makes clear that air pollution is very severe near the main traffic roads. |
