Long-term trends in the ambient PM_2.5- and O₃-related mortality burdens in the United States under emission reductions from 1990 to 2010.

ABSTRACT: Concentrations of both fine particulate matter (PM_2.5) and ozone (O₃) in the United States (US) have decreased significantly since 1990, mainly because of air quality regulations. Exposure to these air pollutants is associated with premature death. Here we quantify the annual mortality burdens from PM_2.5 and O₃ in the US from 1990 to 2010, estimate trends and inter-annual variability, and evaluate the contributions to those trends from changes in pollutant concentrations, population, and baseline mortality rates. We use a fine-resolution (36 km) self-consistent 21-year simulation of air pollutant concentrations in the US from 1990 to 2010, a health impact function, and annual county-level population and baseline mortality rate estimates.
