Odor Measurement in Animal Agriculture

Odors are the most common nuisance complaint associated with animal feeding operations (AFOs), but is one of the most challenging to measure. Unlike other air emissions from AFOs odor is not one easily identifiable gas or molecular compound. Instead, odor is made up of many (hundreds!) of individual odorous compounds. Complicating this scenario is the fact that each person on the receiving end of odor has a different perspective, different tolerance, and different interpretation of what they are smelling. The following materials were developed for college instructors to utilize in their classrooms when presenting about odors.
