    Abstract
  • Aerosol and snow samples were collected at ablation zone of Baishui (白水) Glacier No. 1, Mt. Yulong (玉龙), from May to June, 2006. The concentrations of Cl-, NO3-, SO42-, Na+, K+, Mg2+, and Ca2+ were determined by ion chromatograph both in aerosol and snow samples. The average total aerosol loading is 25.45 neq·scm-1, NO3- 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, SO42- and Ca2+ 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 SO42- and NO3- 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 NO3- in aerosol samples is attributed to motor exhaust emissions from tourism by calculating the SO42- /NO3- 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 SO42-, Mg2+ and Ca2+ are from continental crust sources.
