Abstract
The interdependencies between O3 and PM2.5 formation and how those pollutants respond to emission controls currently and as conditions change in the future were studied. Five cities experiencing elevated O3 and PM2.5 levels were considered, i.e., Atlanta, Chicago, Houston, Los Angeles, and New York. Reductions in anthropogenic NO emissions, due to currently planned emission controls, were predicted to decrease peak maximum 8-hr average O3 (MDA8h O3) levels between 2001 and 2050. Because of VOC-sensitive environments for daily peak ozone formation, the results showed that reductions in anthropogenic NO emissions are expected to increase MDA8h O3 concentrations on more than half of the days in 2001 depending on the city. The response of the annual averages was quite different than peak daily levels for both O3 and PM2.5, thus, health effects associated with acute exposures will respond differently than health effects associated with chronic exposures. This is an abstract of a paper presented at the 101st AWMA Annual Conference and Exhibition (Portland, OR 6/24-27/2008).
