Air pollution mixtures may pose hidden risks during pregnancy
A University of Utah study suggests that exposure to mixtures of multiple air pollutants may increase the risk of preterm birth more than previously thought.

Why it matters
The findings suggest that public health guidelines may need to be updated to account for the synergistic effects of multiple pollutants on maternal and infant health.
