"The purpose of this investigation was to study the magnitude and distribution of sulfur dioxide in the air surrounding the smelter of Missouri Lead Operating Company (now AMAX Lead Company of Missouri) in southeast Missouri, and evaluate the inter-relationships between sulfur dioxide incidents, meteorological factors, and plant operations.

Field research was conducted employing two weather stations and three sulfur dioxide monitoring stations. The data obtained from strip charts at each station were recorded and analyzed manually as well as by UMR computer facilities. From the studies conducted, it was found that the annual predominant winds occurred from S and SE while the seasonal prevailing winds occurred from N, SE, S, WNW and NW. The monthly and seasonal distribution of sulfur dioxide levels showed that about 56 to 93 percent of the time the sulfur dioxide concentrations were less than 0.3 pphm. However, the hourly sulfur dioxide concentrations ranged from 0 to 135 pphm (more than 5 times the 1-hour Missouri air quality standard). The ambient sulfur dioxide level was directly affected by the distance from the smelter, however, the relationship between the distance and pollutant concentration was reversed during high wind periods with large wind frequencies.

The plant operating conditions were found to affect the incident mean and peak sulfur dioxide levels and dosage"--Abstract, page ii.
