HEI has just published its new Strategic Research Plan 2025–2030. This document will guide the organization’s scientific research and related activities through the next five years.

Investigating the Consequences of Measurement Error of Gradually More Sophisticated Long-Term Personal Exposure Models in Assessing Health Effects: The London Study (MELONS)

Klea Katsouyanni
Dimitris Evangelopoulos
Dylan Wood
Benjamin Barratt
Hanbin Zhang
Heather Walton
et al.
2025
Research Report 227
Nitrogen Oxides
Ozone & Oxidants
Particulate Matter
Exposure Methods
Statistical Methods

This report presents a study led by Klea Katsouyanni at Imperial College London. Katsouyanni and colleagues evaluated whether detailed estimates of long-term, personal exposures to outdoor air pollution yield better estimates of the health effects of exposure than less detailed approaches.

Effect of Air Pollution Reductions on Mortality During the COVID-19 Lockdowns in Early 2020

Research Report 224
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.

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

Megan Herting
Elisabeth Burnor
Hedyeh Ahmadi
Sandrah P Eckel
William Gauderman
Joel Schwartz
et al.
2025
Research Report 225
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.

Comparison of Long-Term Air Pollution Exposure from Mobile and Routine Monitoring, Low-Cost Sensors, and Dispersion Models

2025
Research Report 226
Particulate Matter
Traffic-related
Exposure Methods

This report presents a study led by Gerard Hoek at Utrecht University, the Netherlands. Hoek and colleagues compared the performance of a suite of long-term exposure assessment models in the Netherlands for four air pollutants: ultrafine particles, black carbon, fine particulate matter, and nitrogen dioxide.
