EES Air Pollution Seminar: Vehicle Cabin Air Quality: A Micro-Environment That Affect Our Health

University of California, Riverside

Abstract: A lot of resources are spent to reduce emissions from sources. This is beneficial and will have long term benefits. Nonetheless a much more cost effective short term solution is often forgotten. The presentation will introduce current status of exposure while commuting using cars, a mechanism of vehicle ventilation system, benefits of improved vehicle cabin air quality, and related topics. The goal of this line of research was to establish an indoor air quality standard for vehicle cabin air so that exposure while riding a car, which matters in urban areas, can be reduced nationwide and worldwide at a tiny fraction of cost of reducing source emissions.

Bio: Heejung Jung received his Ph.D. from University of Minnesota in 2003. His academic background is thermal/fluid science and aerosol science and he applies those to air quality and vehicle emissions research. He did not know what to do with the air recirculation button at his car. He started vehicle cabin air research from a simple curiosity then he ended up becoming an expert and found a good reason to continue. He is a recipient of SAE (Society of Automotive Engineers) Ralph Teetor Award, SAE Environmental Excellence in Transportation Award and a fellow of SAE. He has worked at Hyundai motors from 1993 to 1998 and conducted his postdoc training at UC Davis from 2003 to 2006 on environmental chemistry to study aerosol health effects.
