| 英文摘要 | Aerosol and snow samples were collected at ablation zone of Baishui (sic) Glacier No. 1, Mt. Yulong (sic), from May to June, 2006. The concentrations of Cl(-), NO(3)(-), SO(4)(2-), Na(+), K(+), Mg(2+), and Ca(2+) were determined by ion chromatograph both in aerosol and snow samples. The average total aerosol loading is 25.45 neq.scm(-1), NO(3)(-) and Na(+) are the dominant soluble ions in the aerosol, accounting for 39% and 21% of average total aerosol loading, respectively. Monsoon circulation reduces the concentration of most ions, indicating that wet scavenging is effective for aerosol particles. In snow samples, SO(4)(2-) and Ca(2+) are the dominant anion and cation, respectively. A lower Na(+)/Cl(-) ratio was found in fresh snow samples compared to the higher ratio that was found in aerosol samples. Analyzing the difference in SO(4)(2-) and NO(3)(-) in air and fresh snow indicated that the aerosol was influenced by local circulation, but the components in fresh snow samples were from long-distance transport. Enrichment of NO(3)(-) in aerosol samples is attributed to motor exhaust emissions from tourism by calculating the SO(4)(2-)/NO(3)(-) ratio in aerosol and fresh snow samples. The temporal variation and correlation coefficients between soluble species in aerosol samples suggest that Cl(-), Na(+) and K(+) come from sea-salt aerosol, and SO(4)(2-), Mg(2+) and Ca(2+) are from continental crust sources. |
