Technical Abstract: Emissions of malodorous chemicals from commercial swine production operations in Iowa are a concern for producers, for local communities, for state regulators, and for offices within USEPA charged with drafting air quality guidelines. In addition to hydrogen sulfide and ammonia, a large suite of semi-volatile organonitrogen and organosulfur compounds contribute to the odor problems associated with swine production. A major route for dispersal of these chemicals is through particulate material. This presentation describes our current efforts at sampling particulate matter, PM-10, from sites adjacent to swine feeding operations and manure storage lagoons. Using a variant of the Graseby- Andersen sampling platform, PM-10 samples are collected on 20 X 25 cm sheets of glass-microfibre filters, and portions extracted with organic solvent mixtures. Instrumental analysis uses isocratic-mode HPLC with identification by both positive- and negative-ion electrospray mass spectrometry. Preliminary results from the first year's sampling are presented.
