| 摘 要： | 应用场发射扫描电镜(FESEM)和带能谱的扫描电镜(SEM-EDX)对哈尔滨市春季市区大气PM2.5的物理和化学特征进行研究。微观图像表明PM2.5颗粒类型主要为矿物、烟尘集合体、飞灰和超细颗粒物;从各种颗粒的数量-粒度、体积-粒度分布及矿物元素分析表明,哈尔滨市大气PM2.5颗粒中,矿物、烟尘集合体、飞灰是颗粒的主要成分,分别来源于扬尘、燃煤燃烧和机动车尾气排放。 |

| Abstract: | A field emission scanning electron microscope (FE-SEM) and energy dispersive X-ray spectroscopy (SEMEDX) were used to examine the inhalable particulates pollution in Harbin during spring season with respect to PM2.5 physico-chemical properties of and the source identification.It has been revealed from the image analysis that the city's particles mainly consist of mineral particles,soot aggregates,fly ash and ultra-fine particulates,which can be traced to the flying dust from construction sites,coal combusti... |
