英文摘要	Aerosol samples were collected in the Shiyi Glacier, Qilian Mountains from July 24 to August 19, 2012 and analyzed for major water-soluble ionic species (F~-, Cl~-, NO_2~-, NO_3~-, SO_4~(2-), Na~+, NH_4~+, K~+, Mg~(2+) and Ca~(2+)) by ion chromatography. SO_4~(2-) and NH_4~+ were the most abundant components of all the anions and cations, with average concentrations of 94.72 and 54.26 neq/m~3, respectively, accounting for 34% and 20% of the total water-soluble ions analyzed. These mean ion concentrations were generally comparable with the background conditions in remote sites of the Qilian Mountains, but were much lower than those in certain cities in China. The particles were grouped into two dominant types according to their morphology and EDX signal: Si-rich particles and Fe-rich particles. Backward air mass trajectory analysis suggested that inland cities may contribute some anthropogenic pollution to this glacier, while the arid and semi-arid regions of central Asia were the primary sources of the mineral particles.
