Research Abstract

The goal of this work is to develop a practical method for the determination of the behavior and deposition flux of the aerosol. The forest canopy could collected 43.2% of the atmospheric aerosol in the diameter range from 1.0 to 2.0 μm. The result of the foliar rinsing method showed that 1/3 to 2/3 of the deposition measured by the Relaxed eddy correlation method was captured by the leaves.
