AMBIENT ATMOSPHERIC AMMONIA EXPOSURE IN AN URBAN COMMUNITY SURROUNDED BY AGRICULTURE

The objective of this study is to estimate long-term individual level ambient atmospheric ammonia exposure for residents of the Champaign-Urbana micro urban area using high spatial resolution air pollution modeling. To achieve this objective, the project includes three tasks: 1) Conduct a two-year ambient ammonia monitoring campaign; 2) Generate agricultural-related geographic covariates that reflect agricultural-related air pollution source and dispersion; and 3) Establish a spatio-temporal atmospheric ammonia predictive model targeting agriculture-related air pollution that estimates individual-level atmospheric ammonia exposure during a two-year period in the Champaign-Urbana micro-urban area.
