摘要：

To understand the physical and chemical characteristics, particle size distribution and sources of size-separated aerosols in Lhasa, which is located on the Tibetan Plateau (TP), six sizes of aerosol samples were collected in Lhasa in 2014. Ca 2+ , NH 4 + , NO 3 − , SO 4 2− and Cl − were the dominant ions. The ratio of cation equivalents (CE) to anion equivalents (AE) for each particle size segment indicated that the atmospheric aerosols in Lhasa were alkaline. SO 4 2− and NO 3 − could be neutralized by Ca 2+ , but could not be neutralized...
