摘　　要：[目的 ]了解上海市居民住宅区PM2 .5的污染状况。 [方法 ]在上海市环境空气质量连续自动监测网络中的一个城市居民住宅区监测点进行了为期 1年的PM2 .5的监测 (TEOM法 )。 [结果 ]PM2 .5年均值 0 .0 60mg/m3 ;月均浓度范围 ( 0 .0 3 7± 0 .0 19)～ ( 0 .10 2± 0 .0 64 )mg/m3 ,日均浓度范围 0 .0 0 6～ 0 .2 5 8mg/m3 。PM2 .5冬季明显高于夏季 ,1月最高 ,8月最低 ;污染水平的变化明显受到交通干道机动车和气象因素的影响。 [结论 ]如以欧美等国家的空气质量标准作评价 ,超标率和超标倍数较高 ;而与美国洛杉矶地区的污染水平相比 ,污染是严重的。Objective] To know the polluted status of PM_ 2.5 in Shanghai urban resident areas,PM_ 2.5 had been monitored for one year on a Shanghai ambient air quality automatic monitoring sub-station site in urban resident area. [Methods] Tapered Element Oscillating Microweighing(TEOM) Method was utilized. [Results] The result indicated that the average of year was 0.060mg/m 3; the average of month ranged from 0.037±0.019 mg/m 3 to 0.102±0.064 mg/m 3,and the average of day ranged from 0.006～0.258 mg/m 3. It had seasonal character that data in winter was much higher than in summer. The highest value was in January whereas the lowest value in August. The variation of pollution was evidently influenced by vehicle flux and meteorologic conditions. [Conclusion] Compared with air standards of some countries in Europe-America,the over-criterion ratio is higher;if compared with Los Angeles,the pollution of this site is more severe.
