中文摘要：
本工作采集了上海市吴淞、南汇和人民广场三个典型地区的PM10、PM2.5样品,对这些颗粒物样品进行穆斯堡尔光谱测量,研究了PM10、PM2.5样品中铁元素的化学种态.研究结果表明,在大气颗粒物中铁元素主要以α-Fe2O3、Fe3O4、铁的硫酸盐以及少量的α-FeOOH的形式存在.
英文摘要：
In the present work, the Moessbauer effect was used to study the chemical species of iron element contained in aerosol particle PM10 and PM2.5 samples collected at Wusong, Nanhui and People＇s Square, the three represent active districts of Shanghai. The results show that the main chemical species of iron were α-Fe2O3, Fe3O4, ferric sulfate and some α-FeOOH.
