抄録

Depth profiles of major anions, cations and trace metal concentration levels were measured on snow samples collected at Ester Dome, Fairbanks, Alaska, in March 1994. Both Ca²⁺ and Na⁺ occupies most of cations and significant amount of non-sea-salt Ca²⁺ exists, especially in late winter snow. Correlation between non-sea-salt SO₄^2- and non-sea-salt Ca²⁺ plus non-sea-salt Mg²⁺ suggests that non-sea-salt SO₄^2- in snow layer deposited in early winter was associated mostly with Ca and a little fraction with Mg. Depth profiles of enrichment factor based on Al for Mn and Ca show a similar variation with depth. Concentration levels and enrichment factors for Pb and V show an increasing trend near the surface, indicating increased input of industrial pollutants to Arctic atmosphere in late winter to spring.
