Air Pollution Exposure, Prefrontal Connectivity, and Emotional Behavior in Early Adolescence

Research Report 225
Megan Herting
Elisabeth Burnor
Hedyeh Ahmadi
Sandrah P Eckel
William Gauderman
Joel Schwartz
et al.
2025
Topics: 
Nitrogen Oxides
Particulate Matter

This report presents a study led by Megan Herting of the University of Southern California, a recipient of HEI’s 2019 Walter A. Rosenblith New Investigator Award. Herting and colleagues examined whether childhood and prenatal exposure to residential outdoor fine particulate matter (PM2.5) and nitrogen dioxide (NO2) was associated with neurodevelopment over a 1-year period in a nationally representative cohort of children ages 9–10 in the United States.

Topics: 
Nitrogen Oxides
Particulate Matter
Accountability

This report presents a study led by Kai Chen of the Yale School of Public Health. Chen and colleagues used the unique scenario of COVID-19 lockdowns in early 2020 to understand how a pause in human activity might affect day-to-day changes in air pollution and the resulting effects on health.

Study examines cardiometabolic effects of air pollutants, noise, and green space

December 18, 2024

HEI has published a new Research Report, Cardiometabolic Health Effects of Air Pollution, Noise, Green Space, and Socioeconomic Status: The HERMES Study. Led by Ole Raaschou-Nielsen of the Danish Cancer Institute, the research team investigated four traffic-related air pollutants (fine particulate matter, nitrogen dioxide, ultrafine particulates, and elemental carbon), noise, and green space in relation to cardiometabolic health in 2.6 million adults in Denmark.
