Atmospheric Concentrations and Sources of Trace Metals at the South Pole
W H Zoller ; E S Gladney ; R A Duce ;
Date 18 Jan 1974
Journal Science, 183 (4121), 198-200
AbstractThe chemical composition of atmospheric particulate material collected at the geographic South Pole indicates that Al, Sc, Th, Sm, V, Mn, Eu, Fe, La, Ce, Co, Cr, Na, K, Mg, and Ca are derived from either crustal weathering or the ocean. The relatively volatile elements Zn, Cu, Sb, Se, Pb, and Br are apparently derived from other sources. Because of their volatility, vapor-phase condensation or a high-temperature dispersion source is suspected for these elements or their compounds.
