矿物颗粒是餐厅和烤肉店空气中的主要成分，为研究餐厅、烤肉店大气细颗粒（PM2.5）中单颗粒的化学组成，用带能谱的扫描电镜识别和统计了两个采样点的单颗粒；依据X射线能谱（EDX）数据，对餐厅、烤肉店的PM2.5颗粒采用P（X）值法，进行元素分类．分析表明：烤肉店样品中出现“C质”颗粒，但餐厅样品没有观察到．餐厅的矿物颗粒在数量上占绝对优势（69.3%）并分为“富Si”“、富Ca”“、富Fe”“、富Cu”“、富Al”“、富Cl”“、富Br”、“富Na”等8种不同类型，其中“富Si”占到43.3%、“富Ca”占到25%；在数量上烤肉店的矿物颗粒物占总颗粒的45.67%，分为“富Si”“、富Ca”“、富Fe”“、富Cu”“、富Ti”“、富Zn”“、富Ca”“、富Na”等“，富Si”占50%“、富Ca”占24.9%；餐厅和烤肉店矿物颗粒的主要类型相同，说明地壳来源是最主要的单颗粒的来源．

Scanning Electronic Microscopy with Energy Dispersed X-ray spectrometry (SEM-EDX) is applied to investigate chemical compositions of the individual particles in the PM2.5 collected in canteen and barbecue store. The SEM-EDX results show that the elements(Si、Ca、Fe、Cu、Al、Cl、Br、Na、Ti、Ga、Zn)of particles based on P(X) value classified few types. The individual particle is dominate with the number-size distribution of the canteen particle (69.3%) and there are“Si-rich”、“Ca-rich”、“Fe-rich”、“Cu-rich”、“Al-rich”、“Cl-rich”、“Br-rich”、“Na-rich”etc. types of canteen particles. The main types of the individual particles were “Si-rich”(43.3%)、“Ca-rich”(25%) in canteen. The mineral particles had the largest quantitative percentage (45.67%) in barbecue store ,and they are classified to“Si-rich”、“Ca-rich”、“Fe-rich”、“Cu-rich”、“Ti-rich”、“Zn-rich”、“Ga-rich”、“Na-rich”etc. There are“C-character”in the barbecue store ,but it isn’t exist in canteen. The main types of mineral particles were“Si-rich”(50%)、“Ca-rich”(24.9%)in barbecue store. The main types of sampling is same, it is indicated that the crust is main source of mineral particles for them.
