Excerpt. © Reprinted by permission. All rights reserved. ABSTRACT An analysis of fine particulate data in eastern North Carolina was conducted to investigate the impact of the hog industry and its emissions of ammonia into the atmosphere. The fine particulate data are simulated using ISORROPIA, an equilibrium thermodynamic model that simulates the gas and aerosol equilibrium of inorganic atmospheric species. The observational data analyses show that the major constituents of fine particulate matter ([PM.sub.2.5]) are organic carbon, elemental carbon, sulfate, nitrate, and ammonium. The observed [PM.sub.2.5] concentration is positively correlated with temperature but anticorrelated with wind speed. The correlation between [PM.sub.2.5] and wind direction at some locations suggests an impact of ammonia emissions from hog facilities on [PM...
