Abstract

The isotopic composition and concentration of lead has been measured in fresh and slightly aged snow collected at Dye 3 in southern Greenland during one full year. The lead concentration displayed large variations ranging from 14-3016 pg/g in April (spring) to 3-6 pg/g in September (summer) while the isotopic ratios changed in regular manner during the year. The ²⁰⁶Pb/²⁰⁷Pb ratios were ~1.15 from spring to mid-summer snow, and increased in late summer to early autumn, reaching ~1.20 in winter. These isotopic data indicate that the lead in the autumn to winter snow originated in North America, while that in spring to mid-summer snow is from Eurasia.
