A National Assessment of the Air Quality and Health Impacts of Vehicle Travel and Electrification: Phase 1 Near Roadway Impacts and Equity Analysis

Principal Investigator Gregory Rowangould, Ph.D.
University of Vermont

This project will address limitations in the current literature surrounding air quality impacts of vehicle traffic, especially in underserved communities. The team will employ a refined near-roadway emission exposure surrogate that balances spatial precision and computational burden to estimate changes in exposure levels and health risks and the distribution of these burdens over time as EV adoption increases.

Bridging Traditional Understandings of Aerosol Dynamics to Real-World Maritime Emissions and Respiratory Health Delivery Methods

Research Product Type

Dissertation / Thesis

This dissertation includes a retrospective of maritime emissions, and a deep analysis of the operational and emission parameters on newest container ships, all with the goal of improving regulations for ship air pollution and reducing personal exposure. The thesis then provides evaluation to establish a novel aerosol delivery method for health studies, aiming to enhance the management of air pollution and its health implications.
