摘要
In order to know the composition characteristics,the background content,and the possible influence of human activities on trace elements in snow and ice in the southern Qinghai-Tibetan Plateau,the concentrations of 15 trace elements,e.g.,Fe,Ba,Cd,Co,Cr,Cu,Li,Ni,Zn,Pb,Sb,Sr,U and V in a 70 cm snow pit which was collected from Qiangyong glacier were determined using inductively coupled plasma sector field mass spectrometry.It was shown that large changes of concentrations exist for different trace elements.The concentrations also change in a large range for the same element.All these indicated that trace elements in the atmosphere of Qiangyong has influenced from both dusts and human activities.
