【 摘 要 】

The sea surfacemicrolayer (SML), although poorly understood, is important in biogeochemicalcycling and sea - air exchanges; it is a source or a sink for a range of pollutants.In this paper, an overview of sampling techniques and the role of SML in biogeochemicalcycles and climate is presented. The chemical and biological nature of the oceansurface film and its interaction with atmospheric aerosols are discussed. Specialattention is given to organic constituents, gel-like compounds, surfactants,halogenated compounds, and metals. Estimates of air - sea exchange fluxes-withfocus on organic carbon, polycyclic aromatic hydrocarbons, and polychlorinatedbiphenyls-are compiled. In addition, research gaps in the chemical compositionof marine aerosols and their relationship with SML are described.
