Aerosol deposition on plant leaves. [Lead]
An aerosol generator and wind tunnel fumigation system designed for use in studies of aerosol deposition on leaf surfaces are described. Gross deposition on rough pubescent leaves was 10 times greater than on smooth, waxy leaves. Results suggest that aerosol deposition, on a per unit area basis, for single horizontal streamlining leaves, is similar to that for arrays of leaves under similar flow conditions.
