Wildfire influence on recent US pollution trends
Published: 2022-12-16
Subjects: Environmental Health and Protection, Environmental Monitoring, Environmental Public Health, Environmental Studies
Steady improvements in ambient air quality in the US over the past several decades have led to large public health benefits. However, recent trends in PM2.5 concentrations, a key pollutant, have stagnated or begun to reverse throughout much of the US. We quantify the contribution of wildfire smoke to these trends and find that since 2016, wildfire smoke has significantly slowed or reversed [...]
