Up in Smoke: How Wildfires Are Redefining Air Pollution in California

The article investigates the trends and disparities in cardiorespiratory health burden related to PM2.5 pollution and wildfires in California from 2008 to 2016. The study finds that the PM2.5-attributed burden decreased, but the fraction attributed to wildfires varied and could constitute up to 15% of the annual PM2.5-burden. The highest burden was observed for respiratory emergency department visits, and disparities in overall morbidity were observed in older, Black, and "other" race groups. Asian populations had the highest risk rate in respiratory outcomes, while high wildfire PM2.5-attributed burden rates in rural, central, and northern California populations occurred due to differential exposure. The study suggests that the impact of wildfires on air quality offsets public health gains achieved through reductions in nonsmoke PM2.5.
