| 摘 要： | 对2005年监测到的南京市大厂地区和山西路PM10浓度值进行分析表明,南京市PM10污染比较严重,其浓度变化范围在0.1157～0.3913mg/m3之间。利用扫描电镜和EMAX能谱分析系统对南京市可吸入颗粒物PM10的微观形貌和能谱进行了研究。结果表明,南京市PM10主要由烟尘集合体、燃煤飞灰和矿物颗粒组成。大厂地区PM10的主要组成成分是燃煤飞灰和烟尘集合体,矿物颗粒不多;山西路PM10的主要组成成分为烟尘集合体,燃煤飞灰和矿物颗粒很少。

| Abstract: | Based on the ambient air monitoring data(monthly-based,yr.2005) of two different(industrial and commercial) districts of Nanjing City respectively,the paper analyzes their seasonal and monthly variations of PM10 concentrations,probing into the trend of weather-dependent PM10 pollution.In addition,energy spectrum and morphological analysis were made for the particulate samples collected in those districts. |
