Evaluate three air dispersion models for predicting near field transport of hydrogen sulfide and odor from livestock and poultry buildings by comparing model results with field measurements, and 2. Measure ammonia emissions from typical swine, dairy, and poultry facilities in cold and spring weather. Project Description Air dispersion models are being used to recommend set back distances for livestock and poultry facilities.
Additional data is needed to improve model results.
Hydrogen sulfide and odor emissions will be measured from three animal facilities. This data will be used as inputs to three air dispersion models to calculate downwind concentrations and odor intensities. MDA Single Point Monitors and trained field sniffers will be used to collect data to compare with air dispersion model results. Ammonia emissions from livestock and poultry facilities are gaining attention because of the potential impact these emissions have on the environment. European researchers have documented a wide range of ammonia emission rates from different types of buildings in different geographic locations.
