The problem of photochemical air pollution continues to be a serious threat to human health and welfare in many areas of the world. Ozone, the primary component of photochemical smog, can impair respiratory functions by causing inflammation and scarring of lung tissue. Because it is a secondary pollutant, control of ozone depends on an accurate understanding of the chemical mechanism leading to its production.
Philip S. Stevens from IU School of Public and Environmental Affairs and Department of Chemistry will describe and discuss current field studies designed to improve our understanding of the chemistry of photochemical smog, including measurements in both urban and remote areas.
