159 Emissions From Confined Animal Feeding Operations

Oral Session
S11 Soils & Environmental Quality Animal production in the United States has significantly consolidated over the past 20 years, with a larger number of animals being produced on an increasingly smaller land base. Associated with this consolidation are the environmental impacts on regional air quality and off-site transport of bioaerosols. This session will highlight the most recent research on trace gas (ammonia and greenhouse gases) and bioaerosol (bacteria, fungi, endotoxin) emissions from poultry, swine, and cattle operations, and management practices. The overall goal is to stimulate discussions and future research pertaining to best management practices that can be implemented to mitigate these emissions.
