| 摘 要： | 在北京市郊区设立采样点，使用Gent采样器收集PM10（直径小于10μm）和PM2.5（直径小于2.5μm）大气颗粒物。利用仪器中子活化分析（INAA）法对2005年春、夏两季采集的样品进行测量，用k0法中子活化分析（ADVNAA软件）对元素含量进行定量计算，得出春季PM2.5平均浓度为41.43μg/m3，PM10平均浓度为140.82μg/m3；夏季PM2.5平均浓度为50.63μg/m3，PM10平均浓度为119.10μg/m3。通过分析可以看出，样品中污染元素随季节、气象条件变化，并通过富集因子来寻找污染元素的来源。JP]

| Abstract: | A sampling station was set up in the suburb of southwest Beijing. PM2.5 (diameter <2.5 μm, fine) and PM10 (diameter <10 μm, coarse) airborne particulate matter (APM) were collected by a Gent stacked filter unit sampler. The samples, collected during spring and summer of 2005, were analyzed by k0 instrument neutron activation analysis (INAA) using the software of ADVNAA. The average volume concentrations of PM2.5 and PM10 APM during spring season are found to be 41.43 μg/m3 and 140.82 μg/m3, respectively, while those during summer season are 50.63 μg/m3 and 119.10 μg/m3, respectively. The major pollution elements and their variations with season and special weather condition are primarily identified by enrichment factor analysis. |
