ObjectiveTo evaluate the efficacy of different control strategies and/or technologies that might aid in the abatement of atmospheric releases of particulate matter and ammonia from commercial poultry operations.
BackgroundLivestock operations are known to generate various airborne pollutants, such as particulate matter (PM) and ammonia, which are considered to be hazardous to human and animal health as well as the environment. Previous studies at the University of Guelph have established baseline emissions from poultry houses (broiler and layer) and have shown that these facilities can contribute significantly to the atmospheric burden of particulate matter and ammonia. These studies have also shown that the emissions of PM and ammonia have diurnal patterns that correspond to activities within the facility (e.g. lights on/or, running of scrapper belts) and that the emissions fluctuate from season to season. Although baseline emissions are essential, determining the level of control or abatement that can be achieved using various technologies or management practices is necessary. The primary goal of this research project is to evaluate different control strategies and/or technologies that might aid in the abatement of atmospheric releases of PM and ammonia from commercial poultry operations. To accomplish this evaluation, ventilation rates and concentration of ammonia and size fractionated particulate matter need to be measured along with production data and litter analysis. In addition, measurements of aerosols and acid and basic gases will also be conducted to determine the effect of the control strategies on the level of secondary reactions in the barn air. Poultry operation to be investigated include: broiler, layer (caged and non-caged) and turkey operations. This activity will help generate a database of abatement strategies for the release of particulate matter and ammonia from various poultry operations.
