Air Pollution Exposure: Modeling

Exposure Assessment:  Modeling

This group of papers develops and applies sophisticated models to simulate and predict human exposure to air pollutants. A key contribution is the development of models for in-vehicle exposure to fine particulate matter and environmental tobacco smoke, as well as the assessment of inter-individual, geographic, and seasonal variability in estimated exposures. This work also includes the evaluation of a new “Microenvironment Tracker (MicroTrac) model,” which uses smartphone data to estimate time-location and improve the accuracy of exposure assessments, thereby strengthening the link between environmental policy and health outcomes.
