Award Description: Amines are volatile organic compounds (VOCs) emitted to the atmosphere from a number of sources including animal feeding operations. (AFOs) Significant literature evidence indicates that amines in the atmosphere act as precursors for fine particulate matter, but the fates of agricultural-related amines have not been studied in a quantitative manner to determine their importance in atmospheric gas and particle chemistry. For this project, we propose an integrated laboratory/field approach to identify and quantify the impact of amines and the role they play in particle formation reactions. The goals of this project are (1) adapt analytical methods to detect particulate-phase amines relevant to the atmosphere, (2) conduct environmental chamber experiments studying the reaction rates and products of amines with atmospheric oxidants and quantifying their aerosol formation potential, and (3) perform several ambient studies of amines in Western state regions impacted by agriculture. During the first year of study, development of methodology for analyzing amine-derivatives will be accomplished. Also, environmental chamber reactions studying reaction rates of amines with atmospheric oxidants will be determined. Year two of the research plan will continue chamber studies with a goal of identifying condensed-phase species that are present in the product particles. Ambient sampling of particles in AFO-impacted air sheds in Utah and California will be conducted and analyzed for the purpose of molecular speciation of amine and amine-derivative compounds. The UCR role in this program will be to facilitate the environmental chamber experiments to be conducted in the CE-CERT environmental chamber. This will include the operation of the chamber facility for amine experiments, collection of data, interpretation of results, and publication of peer reviewed papers. UCR will have a very limited role (provide some technical advice, no committed funds for this portion) in meeting goal 1. UCR will provide a sampling platform for ambient studies conducted in Riverside with very limited personnel and equipment support.
