air quality

Air quality issues associated with animal operations include gas (odorous gases, greenhouse gases -GHGs), odor, VOC, and particulate matter-PM (PM2.5, PM10, and total suspended particulates-TSP) emissions from animal facilities. While some odorous compounds can cause health problems, odors from livestock are mainly a community or individual perception issue. Many different compounds can be the potential cause of odors from animal operations. These compounds can generally be classified as VOCs, odorous sulfur compounds, and ammonia. PM can be emitted directly (i.e., dust) or formed in the atmosphere by the chemical reaction of pollutants such as sulfur oxides, nitrogen oxides, VOCs, and ammonia. The major GHGs associated with agricultural operations are carbon dioxide, methane, and nitrous oxide.
