在地理南极收集的大气颗粒物的化学成分表明，Al，Sc，Th，Sm，V，Mn，Eu，Fe，La，Ce，Co，Cr，Na，K，Mg和Ca来自地壳风化或海洋。相对挥发的元素Zn、Cu、Sb、Se、Pb和Br显然来自其他来源。由于其挥发性，这些元素或其化合物可能是气相冷凝或高温分散源。
The 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.
