"What in the world am I doing to my lungs, and what can I do about
it?" I've often wondered while choking on vehicle fumes during a
run along the Charles River or a ride up Mt. Tamalpais. Air pollution
deleteriously affects not only human health, but also visibility, global
climate, ecosystems, agriculture, and cultural treasures. Our research group
in Air Quality Engineering at Virginia Tech studies emissions to the atmosphere
and their transport and transformation through field, laboratory, and modeling experiments.
Ph.D. student Nina Quadros is measuring emissions of silver nanoparticles from new products and determining what risk they might pose.
