英文摘要	A double focusing inductively coupled plasma spectrometry (ICP-MS) combing with microconcentric-nebulizer was applied to the simultaneous determination of Al, Fe, Mn, Co, Cu, Zn, Sr, Sb, Cs, Ba, Cd, Tl, Pb and Bi in snow and ice in central Asia at the 1 ng/L to 100 mu g/L level. Variation of sensitivity during determination can be calibrated mathematically through monitoring the peak of ArAr. The limits of detection (LOD) of trace elements based on 3 times of standard deviation on 1% HNO3 as blank solution are as follows (ng/L) : Al 40, Mn 6, Fe 40, Co 2. 74, Cu 9. 6, Zn 20, Sr 0. 03, Sb 0. 15, Cs 0. 04, Ba 0. 4, Tl 0. 07, Pb 0. 8 and Bi 0. 05. Measurement repeatabilities of trace elements determined on snow samples from southern Tibetan plateau in terms of RSD were also investigated. The accuracy of the analytical method was verified by the analysis of a certified reference material (SLRS-4, riverine water). The acid effect on the response intensities of trace metals were investigated based on four different nitric acid contents: 0. 5%, 1%, 2% and 4% in samples. The results show that 1% is the appropriate nitric acid (60% Merk Ultrapur HNO3) content in samples while higher response intensities of trace elements can be obtained, as well as considering the large range of concentrations of trace elements in snow and ice samples from central Asia.
