为了研究青藏高原（TP）湿降水中的微量元素，2007年9月至2008年9月在纳木错站共收集了79个基于降水事件的样本。采用电感耦合等离子体质谱法（ICP - MS）分析了样本中铝（Al）、钒（V）、铬（Cr）、锰（Mn）、铁（Fe）、钴（Co）、镍（Ni）、铜（Cu）、锌（Zn）、镉（Cd）和铅（Pb）的浓度。元素的年体积加权浓度总体上与其他背景站点相当，且远低于城市地区。富集因子（EF）表明，与青藏高原土壤相比，湿降水中铬（Cr）、钴（Co）、镍（Ni）、铜（Cu）、锌（Zn）、镉（Cd）和铅（Pb）的浓度升高，这可能表明它们有人为来源。其他富集因子值为……的元素（铝、铁、锰和钒）
To investigate trace elements in wet precipitation over the Tibetan Plateau (TP), a total of 79 event-based precipitation samples were collected from September 2007 to September 2008 at Nam Co Station. Samples were analyzed for concentrations of Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb using inductively coupled plasma-mass spectrometry (ICP-MS). The annual volume-weighted concentrations of elements were generally comparable to other background sites, and much lower than urban areas. The enrichment factors (EF) showed that, in comparison with the Tibetan soils, the wet precipitation had elevated concentrations of Cr, Co, Ni, Cu, Zn, Cd and Pb, probably indicating their anthropogenic origins. Other elements (Al, Fe, Mn and V) with enrichment factor value of
