| Abstract |
A formalism is presented for calculating the ambient concentration of secondary sulfate at any downwind distance from an SO2-emitting point source. The SO2 is assumed to be affected by dispersion, dry deposition and homogeneous gas phase oxidation processes having arbitrary time dependencies. A receptor model estimate of the primary particle contribution at the downwind site is used to account for all of the dispersion and part of the deposition. An important finding is that the secondary sulfate is sensitive only to the average values of the deposition and oxidation rates, and not to their detailed time dependences. Extensions of the formalism to include wet deposition and nitrate formation are also discussed. |
