Atmospheric deposition dominates the landscape cycle of Pb and has a measurable influence on the cycles of Cd and Zn, but a minimal influence on the Mn cycle in a deciduous forest in the eastern United States. Rain event deposition rates are orders of magnitude greater than the intervening dry deposition rates; however, dry deposition supplies 20 to 90% of the total annual input to the forest. Interactions between dry deposition and acid precipitation result in concentrations of metals and H/sup +/ in the canopy 100 to 1000 times higher than rain concentrations alone.
