Abstract

The AA. present here the first data on the seasonal variations of Pb, Cu, Zn, Co and Ba concentrations in the East Rongbuk Glacier which lies on the northern slope of Mt. Qomolangma, spanning from autumn 2005 to summer 2004. They were obtained by analyzing a total of 18 samples collected from a snow pit dug in the East Rongbuk Glacier accumulation area. Seasonal variations of the concentrations and δO 18 are observed, of which Pb, Cu, Zn and Co are much lower in summer monsoon season than that in non summer monsoon season, suggesting that different sources of heavy metals contributed to the site (crustal enrichment factors, anthropogenic sources)
