利用我国“极地号”科学考察船的南极和环球科学考察,采集了太平洋、南极海域、南大西洋、印度洋及航线近岸海域大气的58个气溶胶样品,对Na、Mg、K、Cl、Ca、Br、F进行多元相关分析表明,气溶胶中的Na、Mg、K主要来自海洋,它们之间的比值接近其在大洋海水的平均比值;Cl和Ca在大洋上空也主要来自海水,但近岸海域大气,却明显受到陆源物质输送影响,呈现出不同的Cl/Na和Ca/Na比值;Ca、Br、F在大气中的富集,在大洋上空可能归因于海洋生物活动或海洋微表层富集作用,而在近岸大气,归因于陆源输送影响。
Fifty-eight aerosol samples collected from the Pacific Ocean, the Antarctic waters, the South Atlantic, the Indian Ocean and the coastal off-shore atmosphere were collected from the Antarctic and Global Scientific Expeditions of the “Polar” Scientific Survey Vessel in China. Na, Mg, K, Cl, Ca , Br and F showed that the concentrations of Na, Mg and K in the aerosol mainly come from the ocean and the ratio between them is close to their average ratio in the oceans. Cl and Ca are mainly from seawater over the ocean, but near However, the air in the coastal area is obviously influenced by the terrestrial material transport and shows different ratios of Cl / Na and Ca / Na. The enrichment of Ca, Br and F in the atmosphere may be attributed to marine biological activity or oceanic micro Surface enrichment, while in the near-shore atmosphere, is attributed to the effects of terrestrial transport.
