%X During 1997 September, a 14 m ice core was recovered from an elevation of 7000 m a s l from the Dasuopu Glacier on the northwest margin of Mount Xixabangma in the central Himalayas The variations of major ion concentrations showed that present environmental events had been recorded in the snow of Dasuopu Glacier since 1990 Some evidences indicate that the highest value of SO 4 2- concentration in the core in 1991 may be caused by the pollutants from Kuwaiti oil fires during Persian Gulf War The annual variations of crustal ions (Ca 2+ and SO 4 2- ) concentrations recorded in the firn core may be related to the dust storms happened in spring in northwestern China, and consistent with the variations of dust deposition in 13 cities of Xinjiang Vygur Autonomous Region
