Results of research into particulate sulfur in the Chicago area are presented. An initial filter screening study was run to determine the extent of sulfate artifact formation by different filters, and a spectrograde filter was chosen. Mean, maxima, and minima of the pollutant concentrations were measured for 29 full day collection periods, and the wind speed was vector-averaged. Daily sulfate levels less than 13 micrograms/cu m were found to be linearly related to SO/sub 2/ concentrations. A multiple regression analysis indicated that the total suspended particulates and relative humidity were significant predictors of sulfate variation. Local sulfur emissions were judged to be responsible for 40% of the high atmospheric sulfate content in Chicago during atmospheric conditions which encourage high chemical reactivity.
