The study evaluates the treatment of gas-phase atmospheric deposition in a screening level model of multimedia environmental distribution of toxics (MEND-TOX). Recent algorithmic additions to MEND-TOX for the estimation of gas-phase deposition velocity over vegetated surfaces are evaluated via recently published dry deposition flux measurements. Model results are compared to similar estimates made by National Oceanic and Atmospheric Administration's (NOAA) multilayer dry deposition model. Results of the evaluation indicate that MEND-TOX performs quite well (r squared = .74), for a screening level model, for the estimation of gas-phase dry deposition velocity of nitric acid over soybeans. As long as the stated model assumptions regarding chemical properties are met, the present study expands previous laboratory results for organic species to include some inorganic species and open field and dry leaf conditions.
