| 摘 要： | 采用场发射带能谱扫描电镜(FESEM/EDS)法分析北京怀柔地区PM10与秸秆燃烧排放颗粒的形貌特征和成分差异.结果显示:秸秆燃烧后排放颗粒物多为大粒径颗粒,成分上都含S、Cl和K元素.含有生物质燃烧标志元素K的PM10颗粒物多为含Si、Al和Na元素的燃煤飞灰和矿物颗粒,与秸秆燃烧排放颗粒组成化学元素差异明显.据此推...

| Abstract: | The shape characteristics and the components of PM10 collected in Huairou district, Beijing and the particulates emitted from crop straw combustion were analyzed through field emission scanning electron microscopy combined with energy dispersive spectroscopy (FESEM/EDS). The results showed that most of the particles emitted from straw combustion were large size particles containing S, Cl and K elements. Most of PM10 containing K which was regarded as a sign of biomass combustion also contained Si, Al and Na which come from coal fired fly ash or mineral particles, and was quite different from straw combustion emission particles. Therefore, it concluded that PM10 in Beijing was relatively less affected by crop straw combustion emission, and was significantly influenced by fossil fuel combustion |
