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.
