Cr, Cu, Zn, Co, Ni, Mo, Rh, Pd, Ag, Cd, Sb, Pt, Au, and Uhave been determined in clean room conditions byinductively coupled plasma sector field mass spectrometryand other analytical techniques, in various sections oftwo dated snow/ice cores from the high-altitude (4450 masl) glacier saddle Colle Gnifetti, Monte Rosa massif, locatedin the Swiss-Italian Alps. These cores cover a 350-yeartime period, from 1650 to 1994. The results show highlyenhanced concentrations for most metals in snow/ice datedfrom the second half of the 20th century, compared withconcentrations in ancient ice dated from the 17th and 18thcenturies. The highest increase factors from the pre-1700 period to the post-1970 period are observed for Cd(36), Zn (19), Bi (15), Cu (11), and Ni (9), confirming theimportance of atmospheric pollution by heavy metals inEurope. Metal concentrations observed in Colle Gnifetti snowaround 1980 appear to be quantitatively related to metalemissions from Italy, Switzerland, Germany, France, Belgium,and Austria at that time, making it possible to reconstructpast changes in metal emission in these countriesduring the last centuries.
