| 摘 要： | 将高灵敏度的同步辐射微束x射线荧光光谱分析方法与计算机模式识别技术相结合，用于上海市大气PM2.5，单颗粒物的源识别。分析了污染排放源的PM2.5，单颗粒物，结果表明，来自不同污染排放源的颗粒物具有不同的能谱特征。同时分析了环境空气监测样品PM2.5，单颗粒物，结果表明，在上海市中心区大气PM2.5，的污染源主要以机动车尾气为主，而在吴淞工业区大气PM2.5，的污染源主要以钢铁工业尘和燃煤烟尘为主。

| Abstract: | Synchrotron radiation micro-beam X-ray fluorescence (micro-SXRF) spectrometry combining with pattern recognition technique was applied to identify sources of individual PM_(2.5) airborne particles in ambient air of Shanghai City.The PM_(2.5) airborne particles of different emission sources in Shanghai City were determined.The results show that each emission source has its characteristic micro-SXRF spectrum.Meanwhile,the PM_(2.5) airborne particles in environmental monitoring samples were determined.It was found that the major emission sources of the PM_(2.5) airborne particles were from vehicle tail exhausts in the central city and from metallurgic(industrial) dust and coal combustion dust in Wu-song industry district. |
