The objective was twofold: (1) to characterize the processes governing the deposition of pollutants to individual leaves and plant canopies and (2) to relate deposition to the pollutant's effects on a plant's physiology and growth. The focus is principally dry deposited, regionally distributed gases of importance because of either their phytotoxicity (e.g., ozone, O/sub 3/; sulfur dioxide, SO/sub 2/; nitrogen dioxide, NO/sub 2/; peroxyacetyl nitrate, PAN; hydrogen sulfide, H/sub 2/S; hydrogen peroxide, H/sub 2/O/sub 2/) or influence on biogeochemical cycling in terrestrial ecosystems (e.g., carbonyl sulfide; COS; ammonia, NH/sub 3/; nitric acid vapor, HNO/sub 3/). Where appropriate, the sedimentation of particles and the interception of cloud water by plant canopies and individual leaves are discussed.
