Impact/Purpose:
Congress has mandated that EPA protect the health and welfare of the Nation from hazardous pollutants in air, land and water. The goal of our research is to improve our understanding of the sources, fate and transport of hazardous air pollutants (HAPs) as well as more benign chemical species that can participate/drive the chemical production and destruction of HAPs, e.g. nitrogen. We propose that use of USDA science will improve our characterization of air/land and water surface exchange of nitrogen which in turn should lower exposure risk assessment uncertainty.
Description:
For more than seven years, EPA scientists have been leveraging the USDA Environmental Policy Integrated Climate (EPIC) model to reduce uncertainty in our estimates of agricultural emissions, ambient PM concentrations and subsequent human exposure risk. This presentation summarizes the role this research has played and is playing in meeting EPA’s congressionally mandated mission. Examples of significant EPA applications and ongoing research related to this long collaboration between EPA and USDA scientists are provided and potential future work is briefly outlined.
