A Council for Agricultural Science and Technology study on North American air quality has been released, focusing on the topic as it relates to the areas of swine, poultry, dairy and beef farming.

A few of the study's specific findings, composed from data for odor, hazardous gases, greenhouse gases and pollutant concentrations in animal buildings, include:
• Diet composition has a significant impact on emissions.
• Mitigation methods, such as covering the manure storage surface, can greatly decrease odor emissions.
• Aeration of the storage basin or employing anaerobic digestion of the manure will also reduce the odor, but with higher costs.

Swine production systems generate a large variety of significant air emissions, according to the report. Ammonia, H2S, odor, volatile organic compounds, particulate matter, bioaerosols and greenhouse gases are all emitted in quantities of concern from pork production systems. This has created challenges for pork producers, because a more comprehensive approach (versus targeting one or two contaminants) is necessary to control or manage several of these air emission parameters simultaneously. But the pork industry has been quite progressive in dealing with air quality problems, funding emissions research projects and promoting practices and technologies that manage and mitigate air emissions from their production systems.
