Ammonia Emissions from Animal Agriculture: An Introduction

Air emissions from animal agriculture operations consist of many different gases as well as suspended particulates (dust or microbes). One of these gases, ammonia, is gaining greater attention for its role in odor, but also as a precursor of fine particulate matter (PM 2.5). PM 2.5 has implications in haze and visibility as well as human health. The materials on this page were developed to assist educators and professors who include an introduction to include ammonia emissions as a topic in their classrooms or programs.
