| Abstract |
Integrated quantitative gas chromatographic measurements of the nearly one hundred individual hydrocarbons present in ambient air were made to deternime the total non-methane organic burden at a midwest rural site in coordination with halocarbon, oxidant and local meteorological variables in July and August 1975. Although the sample location was clearly rural, it was only 100 km north of St. Louis, Missouri. Consequently, four situations could be distinguished at this site: clean rural air, transport from near urban areas, transport from distant urban areas, and air-mass stagnation. In the later situation, the rural air was well mixed on a regional scale with natural and anthropogenic ozone precursors. Fluorocarbon-11 and meteorological data were used to identify and describe the four situations and to interpret the observed concentrations of hydrocarbons and oxidant resulting from local photochemistry and transport. |
