2009年7月在天山博格达峰地区四工河4号冰川采集了20个雪坑样品.对所有样品(Na+、K+、Ca2+、Mg2+、NH4+、Cl-、SO42-、NO3-、HCOO-和CH3COO-)进行了分析.与天山地区其它冰川比较,博格达峰四工河4号冰川雪坑中SO24-和NO3-浓度均表现为最高值,分别达到521.4ng.g-1和760.4ng.g-1.2008年12月的多条空气后向轨迹经过了乌鲁木齐市中心;雪坑样品pH值与乌鲁木齐市平均值基本一致,并且雪坑样品[NO3-]/[SO24-]比率与乌鲁木齐市冬天[NO3-]/[SO42-]比率相符合;雪坑样品[HCOO-]/[CH3COO-]比率仅为0.79,低于1.结果表明,博格达峰四工河4号冰川雪样的SO24-和NO3-主要来自于人类污染.
Twenty crater samples were collected from glacier No.4 in the Sijiang River in the Bogda Peak region of Tianshan in July 2009. All samples (Na +, K +, Ca2 +, Mg2 +, NH4 +, Cl-, SO42-, NO3- and HCOO- And CH3COO-) .Compared with other glaciers in the Tianshan Mountains, the concentrations of SO24- and NO3- in the snow pits of No.4 Siberian Glacier in Bogda Peak peaked at 521.4ng.g-1 and 760.4 ng.g-1. The multiple air backward trajectories passed through Urumqi city center in December 2008; the pH value of snow pit samples was basically the same as that of Urumqi city, and the ratio of snow pit sample [NO3 -] / [SO24-] The ratio of [NO3 -] / [SO42-] in winter was consistent with that in snow pit sample [HCOO -] / [CH3COO-], which was only 0.79, lower than 1. The results showed that glacier snow Like SO24- and NO3- mainly from human pollution.
