天山乌鲁木齐河源一号冰川为一中纬度山谷冰川,其冰芯中所记录的生物有机酸计有甲酸、乙酸、草酸和丙酮酸,最近 40年其平均含量分别为(102.8± 147.3),(392.3± 390.8),(6.9± 14.8)和(4.2±8.3) ng/g.甲酸/乙酸平均值为 0.34±0.43.这些生物有机酸源于乌鲁木齐河源周边城市工业生产和人类生活对大气的污染.与极地地区相比,该地区的有机酸远远高于格陵兰和南极洲相应组成的含量,且未经远距离传输和复杂的大气化学反应.
The Glacier in the Tianshan Urumqi Heyuan Glacier is a mid-latitudinal valley glacier. The organic acids recorded in the ice cores include formic acid, acetic acid, oxalic acid and pyruvic acid. The average contents in the recent 40 years are (102.8 ± 147.3) ), (392.3 ± 390.8), (6.9 ± 14.8) and (4.2 ± 8.3) ng / g, respectively. Formic acid / acetic acid average 0.34 ± 0.43. These bio-organic acids originate from the pollution of the atmosphere caused by industrial production and human life in the cities around Heyuan, Urumqi. Compared with the polar regions, the organic acids in this region are much higher than those of the corresponding compositions of Greenland and Antarctica, and are not transported by long distance and complicated atmospheric chemical reactions.
