摘要

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.

Abstract

Scanning Electronic Microscopy with Energy Dispersed X-ray spectrometry(SEM-EDX) is applied to investigate chemical compositions of the individual particles in the PM2.5collected 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"、"Alrich"、"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"、"Ferich"、"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.
