Exposure to fine-particulate air pollution has been associated with increased morbidity and mortality, suggesting that sustained reductions in pollution exposure should result in improved life expectancy.
- This study directly evaluates the changes in life expectancy associated with differential changes in fine particulate air pollution that occurred in the United States during the 1980s and 1990s.
- Results demonstrate a decrease in the concentration of fine particulate matter with an increase in mean life expectancy. It is estimated that reductions in air pollution accounts for as much as 15% of the overall increase in life expectancy in the study areas.
