摘　　要：使用三套新型便携式气悬颗粒物监测仪,分别从季节性变化和污染水平两个方面对大气中的可吸入颗粒物(PM10)与多环芳烃(PAHs)这两种污染物进行了实时监测和分析,并得到了一些初步的结论。初步结果已表明:①大同城市PM10平均日值浓度均高于国家空气质量二级标准;②大同城市空气污染采暖期最重,非采暖期较轻;一天中08时和19时左右污染严重,15时和02时左右污染较轻;③近市中心区点(红旗广场)空气污染相对重些,远离市区点(果树场)空气污染相对轻些。④影响大同城市空气污染浓度变化的主要气象因子是温度、风速和风向。New portable instruments were used to monitor the mass concentration of particle bond polycyclic aromatic hydrocarbons （PAHs） and inhatable particulates （PM10） for 5 days of reaI time in Datong city. The preliminary results show that the particulate pollution in Datong city was very serious and the data measured were higher than the national standard 2nd class; the air pollution in heating time is serious, the non-hesting time is better; the most serious pollution in ＆ day was 08 or clock and about 19 olclock, the less pollution was 15 o＇clock and about 02 o ＇clock the air Pollution is relatively serious near the city center area （the Red Flag square） than the urban district （fruit tree field）.
