| 摘 要： | 2002年在南宁市的5个典型城市功能区内，共采集了125个大气样品(按季节分别采集)，初步调查了大气中颗粒物TSP、PM10、PM2.5的污染状况。结果表明，南宁市TSP、PM10、PM2.5的污染很严重，超标率分别为67．5％、82．5％、92．5％，对人体健康危害更大的PM2．5占到了PM10的63．5％左右。重污染区PM2.5的浓度超过轻污染区近一倍。

| Abstract: | For preliminary investigation of pollution levels of airborne particulate matte in Nanning City,one hundred and twenty-five airborne particulate (TSP, PM-{10}, PM-{2.5}) samples were collected at five typical functional areas of Nanning City during the winter,spring,summer,autumn in the year 2002.The results indicate that the pollution by TSP, PM-{10}, PM-{2.5} is quite serious.The rates exceeding the standards are 67.5%,82.5%,92.5%. The PM-{2.5} fraction,which is more harmful to human health,accounts approximately 63.5% of the PM-{10}, and the concentration of PM-{2.5} at the severe pollution area are approximately one time than at the light pollution area. |
