Abstract

In order to study the scavenging mechanism as a final goal, the characteristics of chemical components in the rain water were examined as a function of the amount of rainfall. The rain drops were collected sequentially with a rainfall interval amount of each 0.1 .sim. 0.5 mm from the beginning of rain. Rain water was separated into the soluble and insoluble components and the concentrations of 15 elements in both components were determined by the PIXE analysis. The elemental cencentrations decreased quickly till about 0.3 .sim. 0.5 mm of rainfall was obtained and then decreased gradually afterward. Fe, Ti, and Si in the aerosol particles caught in rain water were in high insoluble state. In contrast, almost whole of S and Cl were dissolved in rain water.
