Jun Wang, EHSRC Member and Lichtenberg Family Chair in the Department of Chemical and Biochemical Engineering, is the corresponding author for a study published in the journal Science that found that ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air.
The study also found that the increase in wildfire-driven ozone pollution over the past decade has undercut air-quality improvements achieved before 2015, largely through reductions in automobile emissions, which are a main contributor to surface ozone.

Chronic diseases including cancer, diabetes, Parkinson’s Disease, chronic respiratory disease, and childhood neurodevelopmental disorders have increased dramatically in the United States over the past few decades. Research shows that these diseases are linked to environmental factors such as air pollution, microplastics, and harmful chemical exposures.
NIEHS is at the forefront of conducting research that protects public health by revealing how environmental factors impact health and disease and supporting communities in responding to environmental disasters such as chemical spills and extreme weather events like hurricanes. NIEHS P30 environmental health research centers are at the core of this mission by advancing scientific understanding, addressing emerging public health threats, improving community health, and reducing health care costs.
