Measurements of SO/sub 4//sup 2 -/ 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. Comparisons among the four types of surrogate surfaces show deposition velocities which increase in the order Teflon sheets approx.Teflon plates
