In this study, we estimated the total Emissions mortality resulting from long-term PM2.5 and O3 exposures in California in 2012 using multiple concentration Fine particulate matter response functions (CRFs) and attributed the estimated mortality to different emission groups. The point esti- Ozone mates of PM2.5-associated mortality in California ranged from 12,700 to 26,700, of which 53% were attributable Mortality to in-state anthropogenic emissions.
