Abstract The extent of oxidation of sulfur dioxide to sulfate was measured at two coal-fired and four oil-fired power plant plumes. Samples were collected at various distances downwind of the source by employing a high-volume filter pack in a fixed-wing aircraft. Particulate sulfur to total sulfur concentration ratios and exp 34 S to exp 32 S isotope ratios were measured and interpreted. In almost all instances essentially all of the oxidation was found to occur during the first few kilometers of plume transit and even when plumes were followed for more than 70 kilometers. In the coal-fired plumes the extent of oxidation seldom exceeded 4 percent, one-third of which could be attributed to primary sulfate production during the combustion of the coal. In the oil-fired plumes the extent of oxidation was approximately twice that observed for coal. However, the primary production of sulfate is much more variable and probably higher during oil-fired operations and could account for some of the apparent difference observed for the atmospheric oxidation. In addition, there is some indication that sulfate could be dropping out of the power plant plumes which might cause observations of sulfate formation to appear to be less than their true values.
