000027851 520__ $$aThe environment of Mt. Qomolangma (Everest) area is of great significance to the global environmental background and environmental change research. However, there are few studies on the content and distribution of soil trace elements in the area. About 130 soil samples were collected nearby the Rongbuk valley at the northern slope of the Qomolangma from 4,400 to 6,600 m elevations. Nine soil trace elements, Cr, Zn, Sr, Pb, Ni, Co, Cd, Mn, Cu, were analyzed with ICP-AES (inductively coupled plasma atom emission spectrometry). The results showed that soil trace elements content increased with altitude; the content of the Cd in this area was very high, which was 5.8 times of the average content of Chinese soil. There was a noticeable change point for soil trace elements content at the altitude of 5,800 m, and the content of Cd increased abruptly above 5,800 m. This point was just located at the boundary of two types of rocks. The Late Precambrian-Neoproterozoic granite–gneiss and metacryst migmatized interbedded with marble located below 5,800 m; black-dark slate and marl of Cambrian located above 5,800 m (including 5,800 m), the geochemical characteristic of different rocks was the main factors controlling the soil trace elements content in the northern slope of Qomolangma Mountain.
