Air Pollutants and their environmental fate and effects

INTRODUCTION

Oak Ridge National Laboratory researchers are supporting the Office of Air Quality Planning and Standards of the U.S. Environmental Protection Agency to develop the Total Risk Integrated Methodology (TRIM). TRIM is a comprehensive risk modeling system to use in human health and ecological risk assessments of air pollutants. ORNL has aided in the development of TRIM.FaTE, a fate, transport and exposure model, one of three modules in TRIM. Collaborators include: ICF Consulting, Lawrence Berkeley National Laboratory, and MCNC-North Carolina Supercomputing Center. The team is currently evaluating the performance of the model, which has been parameterized for mercury and polycyclic aromatic hydrocarbons.
