Research Reports

HEI’s mission is to provide credible science to support environmental regulations and other policy decisions. The results of each HEI-funded project undergo peer-review by outside scientists and the Health Review Committee. The HEI Research Reports contain the Investigator’s Report and the Review Committee’s evaluation of the study, summarized in a Commentary or short Critique.

This report presents a study study led by H. Christopher Frey of North Carolina State University in Raleigh. The investigators measured six air pollutants (nitrogen oxides, ultrafine particles, black carbon, fine particles, nitrogen dioxide, and ozone) near a freeway and in an urban area.

This report presents a comprehensive HEI study examining potential health risks from low levels of air pollution exposure in millions of Canadian citizens. Michael Brauer at The University of British Columbia and his colleagues combined satellite data, air monitor sampling, and atmospheric modeling to estimate outdoor PM2.5 exposures across Canada from 1981 to 2016.

Research Report 209 presents a study by Mònica Guxens of the Barcelona Institute for Global Health (ISGlobal) and colleagues. The team used new neuroimaging technology to assess the possible relationship of air pollution exposure during pregnancy and childhood with brain outcomes in children.

Research Report 211 presents a major HEI study by Dr. Francesca Dominici of the Harvard T.H. Chan School of Public Health and colleagues. The investigators examined the risk of mortality associated with exposure to low ambient air pollution concentrations in a cohort of 68.5 million older Americans.

2021

Research Report 210 presents a study conducted by Dr. Erin McDuffie and Dr. Randall Martin of Washington University in St. Louis, Missouri, Dr. Michael Brauer at The University of British Columbia in Canada, and colleagues. The investigators produced the first comprehensive global estimates of contributions from the most common sources of air pollution to people’s exposure to fine particles and to the world’s burden of disease from various causes.

Research Report 208 presents a study by Bert Brunekreef at the Institute for Risk Assessment Sciences, Utrecht University, the Netherlands, and colleagues examining associations between exposures to relatively low levels of air pollution below the current EU standards and several health outcomes among participants in 22 European cohorts.

2021

Research Report 206 presents a study led by Dr. Jane Clougherty at Dornsife School of Public Health, Drexel University. Clougherty and colleagues examined whether associations between community- and individual-level cardiovascular disease events and ambient air pollutants vary by social stressors.

Research Report 204 presents a study led by Dr. Kymberly Gowdy of East Carolina University (now at Ohio State University) and colleagues in which they evaluated how acute exposure of mice to ozone affects initiation and resolution of the inflammatory response in the lung.

Research Report 201 presents a study led by Dr. Lydia Contreras at the University of Texas, Austin, who is a recipient of HEI’s Walter A. Rosenblith New Investigator Award. Dr. Contreras and colleagues evaluated how exposure of lung cells to volatile organic compounds plus ozone affects oxidation of ribonucleic acid, a key component of cells. The study aimed to improve understanding of the biological mechanisms by which air pollutants can cause effects in human health, thereby expanding our knowledge of potential causal links between exposure and health.
