RECOMMENDATION: Best management practices (BMPs) aimed at mitigating AFO air emissions should continue to be improved and applied as new information is developed on the character, amount, and dispersion of these air emissions, and on their health and environmental effects. A systems analysis should include impacts of a BMP on other parts of the entire system.

SUMMARY

This chapter described the various constituents of air emissions that are of primary interest and the factors that determine emissions rates and dispersion as they affect atmospheric concentrations. The effects of temporal and spatial factors are described along with the complexities of modeling the flow of emissions over complex terrain as they affect field measurements. Potential impacts of these air emissions on human health and the environment are described and put in the context of expected rates and concentrations of emissions from animal feeding operations.
