大气气溶胶干沉降对海域微量金属输入的研究现状

Recent Researches on the Input of Trace Metal Elements to the Oceans via Atmospheric Aerosol Dry Deposition

对国内外学者近年来在大气干沉降对海域微量金属输入方面的研究工作做了较为系统的综述 :包括样品采集、分析、干沉降通量估算和污染物来源识别。重点讨论了常用分析方法的优缺点以及它们在气溶胶物理、化学性质研究中的应用和已取得的成果 ,旨在为气溶胶分析方法的选择提供参考。

The recent researches on the input of trace metal elements to the oceans via atmospheric aerosol dry deposition are reviewed. They include four aspects: aerosol sampling, measurement and analysis, the estimation of dry deposition flux and aerosol source identification. Each analytical technique has its own advantages and disadvantages, which are discussed in detail. To provide reference to the selection of analytical methods, the application and achievement of these techniques in the measurement of physical chemical properties of aerosols are also reported.
