Objectives

Determine the odor emission factors of selected animal buildings that are participating in the National Air Emission Monitoring Study (NAEMS) for use in air dispersion and evaluation of control technologies. Develop a comprehensive chemical library that delineates the most significant odorants and correlates this with olfactometry results. Also disseminate this information to researchers, the regulation community, and other stakeholders.

Need or Impact

There is a great need for correlating the olfactometry responses and chemical odorants to provide a more objective measure of the odor impacts on communities and other individuals near animal production facilities. Also there is a need for more and higher quality odor emission data for air dispersion studies and siting tools.

Project Status

To date this project is still on hold since the National Air Emission Monitoring Study (NAEMS) has not yet started. NAEMS is due to start taking data toward the end of 2006, so hopefully some odor data and chemical odorants will begin to be collected starting in 2006 and continuing through 2007 and into 2008.
