| 中文摘要 |
| 重点研究青岛沿海地区大气气溶胶的海盐来源 .在 Na主要来自于海盐 ,Cl存在亏损的情况下 ,为确定大气气溶胶中的海盐源贡献率 ,将 Na和 Cl作为海盐源参比元素计算得到的海盐源贡献率分别作为上限和下限 ,得出青岛沿海地区大气气溶胶中海盐源的年均质量浓度贡献率大致为 6.3%～ 9.7%.海盐源对气溶胶的贡献随气溶胶粒径增大而增加 .青岛沿海大气气溶胶氯亏损在 36.2 %～ 65.9%范围内 ,是大气中气态无机氯的来源之一 . |
| 英文摘要 |
| This paper focused on discussing the sea salt source contribution to the aerosol in coast area of Qingdao.Due to most of the Na coming from the sea salt aerosols,and Cl depletion,the range which sea salt contributes to the coast aerosol was estimated by using Na and Cl as the indicators,respectively.The annual average contribution of sea salt source to the aerosol in Qingdao seashore area is about 6.3%～9.7%.Sea salt source contribution to the coast aerosol increased with the diameter of particulate.The chloride depletion in aerosol varied from 36.2%～65.9%,as one of the source contributing to the gaseous inorganic chloride in the atmosphere. |
