【 摘 要 】

The relative contributions of PM_2.5 and ozone precursor emissions to air pollution-related premature mortality modulated by climate change are estimated for the U.S. using sensitivities of air pollutants to precursor emissions and health outcomes for 2001 and 2050. Result suggests that states with high emission rates and significant premature mortality increases induced by PM_2.5 will substantially benefit in the future from SO₂, anthropogenic NO_X and NH₃ emissions reductions while states with premature mortality increases induced by O₃ will benefit mainly from anthropogenic NO_X emissions reduction. Much of the increase in premature mortality expected from climate change-induced pollutant increases can be offset by targeting a specific precursor emission in most states based on the modeling approach followed here.
