Abstract

The dry deposition rates on various grass fields and two forests have been measured by the use of 212Pb (T1/2 = 10.6 hours). The deposition rate on grass fields (average: 7 mm·s-1) roughly depends on the logarithms of the heights or densities of the grasses. The dry deposition rates on a broadleaved forest (Lithocarpus edulis) and a coniferous forest (Cryptomeria Japonica) were also measured. The highest (ave. 26 mm·s-1) was on the forest of C. Japonica because of the dense and adhesive surfaces of the leaves.
