Coadsorption at the air/water interface likely explains some pollutants transfer to the atmosphere: Benzene and lead case

Abstract

This study attempts to evidence a physical interfacial mechanism for the passing of some non-volatile harmful molecules from water, where they are dissolved, to the atmosphere. The idea developed here is that an organic substance, at its solubility limit, forms a surface layer whose properties induce the coadsorption of another dissolved substance; both are then able to pass to the atmosphere by a bubbling mechanism. Experiments were made with benzene close of its solubility limit in an aqueous solution of lead nitrate, which is non-volatile and normally does not adsorb at water surface. Coadsorption really occurred. The impact of such a mechanism on the environment is discussed. © 2003 Elsevier Science Ltd. All rights reserved.
