The Health of the Air report provides estimates of the health impacts associated with outdoor air pollution in every city in the US. Health impacts are estimated for air pollution levels greater than recommended by the American Thoracic Society (ATS). This year's report also provides the first local estimates of the adverse health impacts from wildland fires.

Health impacts from outdoor concentrations of PM2.5 greater than ATS recommendations (8 µg/m3 for long-term PM2.5; 25 µg/m3 for short-term PM2.5).
Areas already meeting these recommended levels are expected to benefit from further improvements in air quality but these additional health benefits are not included in this analysis.

Health impacts from outdoor concentrations of O3 greater than ATS recommendations (60 ppb).
