In this study, the deposition of SO{sub 2} and HNO{sub 3} was measured to three tree species, elm, oak and pine. Earlier work has shown that these three species cover of physical types (smooth oak leaves, rough elm leaves, and needles) and chemical types (acid and alkaline leaves) The total deposition is compared to the deposition measured through the stomata. After deposition, removal by revolatilization or extraction was determined. The data is used to estimate dry deposition fluxes of SO{sub 2} and HNO{sub 3} to forests that can then be combined with wet fluxes to determine total atmospheric inputs. Based on these results, a preliminary estimate is made of the possible detrimental effects to forests from atomspheric inputs.
