Abstract

Measurements of SO2-4 fluxes to surrogate surfaces have been conducted as part of the Dry Deposition Intercomparison Study in Champaign, Illinois. Data for Teflon plates without rims and for polycarbonate petri dishes with 1-cm rims have been obtained and compared with data for Teflon sheets and polyethylene dustfall buckets used by other investigators. Results show that deposition velocities for the Teflon plates are in the range of 0.17-0.42 cm/s, while corresponding values for the petri dishes are in the range of 0.18-0.61 cm/s. Overall, the results of this study suggest that inertial impaction and sedimentation of supermicron airborne particles are more important than deposition of submicron material in influencing total SO2-4 mass deposition onto surrogate surfaces and onto natural vegetation at this site. -from Authors
