英文摘要	Formate (HCOO-), acetate (CH3COO-), oxalate (C2O42- and pyruvate (CO)C2O42-) are detected in a 14.08-m-long ice core recovered in Glacier 1 at the Urumqi riverhead, Tianshan, China, which is a mid-latitude alpine glacier (43 degrees 06'N, 86 degrees 49'E). the mean concentrations for the four organic acids in recent four decades are (102.8 +/- 147.3), (392.3 +/- 390.8), (6.9 +/- 14.8) and (4.2 +/- 8.3) ng/g, respectively, with the ratio for HCOO-/CH3COO- of 0.34 +/- 0.43. They represent the major acid components, and originate mainly from anthropogenic emission in the nearby industrial cities. Compared with Greenland and Antarctica, Glacier 1 is much higher in carboxylic acids, which were not subjected to long distance transportation as well as complicated atmospheric reactions. The alpine glacier can be, therefore, useful to reconstructing human pollution scenario to the regional atmosphere.
