| 摘 要： | 应用扫描电子显微镜(SEM)研究长春市区初冬季节(2015年10月)可吸入粒子(PM_(10))的微观形貌并探讨其来源。结果表明,长春市区的可吸入颗粒物主要有:烟尘集合体、燃煤飞灰、矿物颗粒及未知颗粒,其中雾霾天气下以烟尘集合体和燃煤飞灰为主。长春市周边及邻近省份地区农业生物质燃烧是初冬季节雾霾天气下PM_(10)的主要来源。

| Abstract: | Morphology and sources of inhalable particle (PM10) were investigated using scanning electron microscopy (SEM). The results showed that four main types of particles were identified including soot aggregates, fly ashes, minerals and the unknown particulate, of which soot aggregates and fly ashes were the main particulates in a pollution haze. The combustion of agricultural biomass around Changchun and its neighboring provinces was the main source of PM10 in the early winter accompanying a haze condition. |
