Summary

The overall goal of the project is to fully develop, employ and verify a technique to quantify the contribution of agricultural soils entrained in the atmosphere to ambient fine and coarse particulate matter (PM). This project tests the hypothesis that the carbohydrate species present in agricultural soils are chemically distinct from organic components in native soils as a result of soil improvements designed to raise the organic content and productivity of agricultural soil. This project will focus on comparison of the concentrations of marker species in agricultural soils to unimproved soils, and attempt to separate agricultural emissions from other fugitive dust sources (such as windblown dusts, unpaved road dusts or construction dusts).
