以日照市为研究对象,通过采集雾霾天气大气颗粒物样本,利用扫描电子显微镜、ICP-MS等工具对其进行形态特征分析,探讨了 日照市雾霾天气大气颗粒物(PM2.5)的微观形态特征及其来源.结果表明:日照市PM2.5颗粒物主要以无定形态为主,为含铁、镁、铝、钾、钠的硅酸盐颗粒;日照市PM2.5的主要来源包括道路扬尘及建筑施工排放、交通汽车尾气排放、燃煤、电子垃圾拆解等.通过对日照市PM2.5微观形态特征和来源的研究,可为改善日照市的大气环境质量提供科学依据.
The atmospheric particulate matter samples in haze weather were collected from Rizhao city,their morphological characteristics by using scanning electron microscope,ICP-MS and other tools were analyzed,and the micro-morphological characteristics and sources of particulate matter(PM2.5)in Rizhao during haze weather were investigated.The results showed that the PM25 particles in Rizhao were mainly amorphous,which mainly were silicate particles containing iron,magnesium,aluminum,potassium and sodium.The main sources of PM2.5 in Rizhao include road dust and construction emissions,vehicle emissions,and the coal burning and dismantling of e-waste.The study on the micro-morphological characteristics and sources of PM2.5 in Rizhao can provide scientific basis for improving the air quality in Rizhao.
