Wildfires now the dominant contributor to unhealthy levels of air pollution for pregnant women in the US

Wildfires are well-known health risks. Now, in a new Frontiers in Environmental Health study, researchers in the U.S. have—for the first time—evaluated how prenatal PM2.5 exposure has changed over space and time on a national scale and what role wildfires play in shaping these trends.

Wildfires now lead unhealthy air pollution exposure among pregnant women in

Wildfire smoke has become an increasingly important source of prenatal air pollution in the United States, even as overall exposure to fine particulate matter has declined. A new study published in Frontiers in Environmental Health has examined this changing pattern across the country, analyzing how exposure to PM₂.₅ during pregnancy varied between 2003 and 2019 and identifying the growing role of wildfire emissions in shaping pollution levels. …
