Bill Nazaroff to give CEE Spring Distinguished Lecture

Featured Faculty: William W Nazaroff

William Nazaroff, the Daniel Tellep Distinguished Professor, will be the honored speaker at the CEE Spring Distinguished Lecture on March 6, 2018.

Bill will speak on "Air Around Us: Science, Technology, and Health."

The lecture will be held in Banatao Auditorium, Sutardja Dai Hall, 5-6pm.  A reception will follow the lecture in the adjoining atrium.

The lecture and reception are free and open to the public.

Abstract


Although we do it about fifteen times per minutes, awake and asleep, our breathing rarely merits a thought.  Yet, over our lifetimes, we can each expect to inhale about 300 tonnes of air.  Most of that is indoor air. Although influenced by the atmosphere’s composition, the air we breathe is modified by processes that occur in the indoor environments in which we spend most of our time. 

This lecture features three vignettes illustrating recent progress that advances knowledge about indoor air quality.  The first concerns exposure to ozone in passenger cabins of aircraft. Airplanes can fly through areas where high ozone levels occur naturally; exposures in the cabin raise health concerns not only because of ozone itself, but also from the volatile byproducts of its reactions with our skin oils.  

The second investigation concerns airborne particles in neonatal intensive care units.  The vulnerable population of premature infants is protected from outdoor air pollution by highly efficient particle filters.  In this well-controlled environment, resuspension and shedding from occupants are major residual sources of airborne particles.  This finding has led us to study clothing as a transport vector for airborne particles, potentially including infectious agents.

Third, we are utilizing state-of-the-art scientific instruments for measuring the dynamic behavior of volatile organic compounds in the air of ordinary indoor spaces, including classrooms and residences.  Advanced analytical capability combined with deep domain knowledge is yielding surprising new insights about chemicals we commonly encounter indoors.  

Being so fundamental to our well-being, the composition of the air around us is worthy of our attention. To better understand how air quality influences the human condition, indoor air deserves as much research and policy attention as the other parts of our environment.
