Research Report 190 describes a study by Frank Gilliland and colleagues that was funded under HEI’s Accountability research program. The investigators collected air quality data and lung function and respiratory symptoms in three cohorts of children who participated in the Children’s Health Study in Southern California. During the 20-year study period, nearly 20 major policy actions were implemented to reduce pollution from transportation and other sources. Gilliland and colleagues evaluated whether the improved air quality was associated with improved lung function and respiratory symptoms in these children.

This report describes a study that analyzed the relationships between reductions in pollutants from power plants and fine particulate matter (PM_2.5) concentrations in the eastern United States between 1999 and 2005. Dr. Richard D. Morgenstern of Resources for the Future and colleagues used a novel data-driven source-receptor model to explore the statistical relationships between source emissions of sulfur dioxide (SO₂) and nitrogen oxides and monitored concentrations of PM_2.5. They performed various external comparisons of their models, and compared the reductions to an estimated counterfactual scenario in which no mandated reductions in SO₂ occurred.
