Description:
In conjunction with the Regional Air Pollution Study being conducted in the St. Louis Air Quality Control Region (AQCR), a methodology for estimating the amount of sulfur trioxide (SO3) emitted by combustion sources was developed. It is based on SO2/SO3 ratios determined both experimentally and from literature surveys. The most likely value appears to be 1.85% of the SO2 emissions. On this basis, about 22,000 tons of SO3 are emitted yearly from combustion sources. A fine particle size inventory for the area was also developed. The inventory gives a breakdown of particulate emissions in the range of 7 to .01 microns, based on production rates and collection efficiencies for point sources in the St. Louis AQCR. The information on the SO2/SO3 ratios and the particle size breakdown is stored in the RAPS Data Handling System.
