Wildfire smoke is now the primary pollutant affecting pregnancy, study shows

A new study analyzing pollution levels over a 16 year period reveals that wildfire smoke has become the primary pollutant affecting pregnancy. Although general pollution levels have significantly declined during this timeframe, the recent increases in air pollution caused by wildfire smoke have offset those gains. The research highlights a shift in environmental risks, where the benefits of reduced general pollutants are now countered by the rising prevalence of smoke from wildfires.
