The Health Impacts of Air Pollution, 2008-2017

Trends in Excess Morbidity and Mortality Associated with Air Pollution

+ Kevin Cromar, Laura Gladson, Gary Ewart

Conclusions

Improvements in health impacts attributable to ambient PM2.5 concentrations have been observed across most regions of the United States over the last decade, although the rate of these improvements has leveled off in recent years. Despite two revisions of the National Ambient Air Quality Standards strengthening the standard for O3 in 2008 and 2015, there has not yet been a substantial improvement in the health impacts attributable to O3 during this time period. In many U.S. cities, an increase in the exposed population over the last decade has outpaced the improvements in ambient O3 concentrations, resulting in a net increase in O3-related health impacts over time.
