Modeling mortality risk tied to air pollution

Peer-Reviewed Publication

Proceedings of the National Academy of Sciences

Researchers used data from studies on outdoor air pollution in 16 countries to construct a model for estimating the exposure and mortality risk related to fine particulate matter (PM2.5); the model predicted a significantly greater number of avoidable deaths than a standard mortality risk model in a scenario with a 20% reduction in PM2.5 concentrations based on PM2.5 exposure estimates for 2015, suggesting that the health benefits tied to reducing PM2.5 concentrations are likely greater than previously thought.
