| 摘 要： | 报道了西太平洋海域上空气溶胶的变化情况.尘土粒子的输入量控制着海洋上空气溶胶中元素Al、Fe、Sc、Mn、Co、La、Ce、Eu、Hf、Ta及Th的浓度.相对于海洋和地壳来源的异常富集元素在西太平洋上空气溶胶中富集程度很高.在开阔海域大气中的海盐元素浓度受海盐气溶胶粒子的量所控制,而其它元素则受来自陆地的地壳风化物影响.由于环境污染物的输入.使开阔海域大气的化学组成发生了变化.

| Abstract: | This paper reports an investigation on the variabilities of marine aerosols over the western Pacific Ocean. Atmospheric inputs of dust soil particles control the marine aerosol particle concentrations of Al, Fe, Sc, Mn, Co, La, Eu, Hf, Ta and Th. High abundance of anomalously enriched elements relative to oceanic and crustal sources was observed. In the atmosphere of remote marine areas, the concentrations of a number of trace elements are controlled by the production of sea-salt aerosol particles, while others are dominated by transport of weathered crustal material from the continents. Environmental contaminants have altered its composition, even over remote regions. |
