| 摘 要： | 应用扫描电镜技术(SEM/EDX)对南京市两典型地区PM10中颗粒的微观形貌及其矿物组成进行了研究.结果表明,南京市大厂区(典型工业区)PM10中的颗粒多以形态规则矿物颗粒为主,山西路地区(典型商业区)PM10中的颗粒多以形态不规则出现,形态规则颗粒主要是碳酸盐、硫酸盐和铝硅酸盐矿物,形态不规则颗粒主要是烟尘结合体、生物质和原生矿物. |

| Abstract: | Micro morphology and mineral composition of PM10 in Nanjing typical areas were studied using scanning electronic microscopy (SEM/EDX). The SEM/EDX analysis showed that mineral particles with regular shapes were popular in PM10 in Dachang District, and mineral particles with irregular shapes were popular in PM10 in Shanxilu Area respectively. The composition of mineral particles with regular shapes were mainly carbonates, sulphates, and aluminosilicates, while mineral particles with irregular shapes were mainly soot aggregates, biomass and primitive minerals. |
