摘　　要：对上海市PM_(2.5)的污染现状进行了调查与分析,在2000～2001年间对上海市7个采样点的PM_(2.5)进行了样品采集,初步得到了上海市PM_(2.5)浓度的时间变化规律。全市7个监测点的PM_(2.5)年平均浓度值为60.1μg/m^3,其中市区6个监测点PM_(2.5)的年平均浓度值为65.2μg/m^3,清洁对照点南汇监测点PM_(2.5)的年平均浓度值为41.3μg/m^3;市区冬季的PM_(2.5)月平均浓度值最高,达到80.2μg/m^3,夏季的PM_(2.5)月平均浓度值最低;为35.9μg/m^3,春季和秋季的月平均浓度值分别为72.6μg/m^3和70.4μg/m^3。上海的年平均PM_(2.5)浓度值与美国的标准值(15μg/m^3)相比,超标情况是相当严重的。The PM2.5 samples were collected at 7 sites during 2000-2001 in Shanghai and monthly continuous monitoring has been taken separately in Oct. 2000, Jan. 2001, Apr. 2001 and Jul. 2001. The highest PM2.5 concentration was 185.9ug/m3 appearing at Baoshan monitoring site, and the lowest was 2.9ug/m3 appearing at Nanhui monitoring site. The annual average of PM2.5 concentration was 60.1ug/m3 at 7 monitoring sites in the whole city of Shanghai. Among 7 monitoring sites, it was 65.2ug/m3 at 6 monitoring sites in urban area and 41.3ug/m3 at control site in Nanhui The highest monthly average of PM2.5 concentration was 80.2ug/m3 in winter and the lowest was 35.9ug/m3 in summer. PM2.5 pollution in Shanghai is quite serious comparing with the US standard (15ug/m3).
