Study examines real-world emissions characterization in two traffic tunnels

March 26, 2019

HEI has published Research Report 199, which describes a study led by Dr. Xiaoliang Wang at the Desert Research Institute in Reno, Nevada. Wang and his colleagues sought to evaluate how mobile-source emissions have changed through real-world emission characterization in two traffic tunnels: the Shing Mun Tunnel in Hong Kong and the Fort McHenry Tunnel in Baltimore, Maryland.

Examining air pollution and neurocognitive effects in older women

October 12, 2017

HEI has published Research Report 193, which describes a novel study of older women in the United States led by Jiu-Chiuan Chen of the University of Southern California. The investigators examined the possible association between long-term exposure to ambient particulate matter and changes in brain volumes and in neurocognitive outcomes, specifically mild cognitive impairment and dementia.

Research Report 193 describes a novel study by Jiu-Chiuan Chen and colleagues examining possible associations between long-term exposure to ambient particulate matter (PM) and changes in the brains of older women in the United States. The study focused on brain volumes and neurocognitive outcomes, specifically mild cognitive impairment and dementia. Dr. Chen used neuroimaging and cognitive outcome data from women enrolled in the Women’s Health Initiative Memory Study and estimated their exposure to ambient PM2.5 and to diesel PM.

Communication - ACES
Health Effects Institute
December 2015

This Executive Summary of the Advanced Collaborative Emissions Study (ACES) summarizes the main findings of emissions and health testing of new-technology heavy-duty diesel engines capable of meeting US 2007/2010 and EURO VI/6 diesel emissions standards. The results demonstrated the dramatic improvements in emissions and the absence of any significant health effects (especially cancer). ACES was the most comprehensive examination done to date of engines meeting the US 2007 and 2010 on-road standards.

Special Report 19
HEI Diesel Epidemiology Panel
November 2015

Special Report 19 contains the intensive review and analysis of the newest studies of mine and truck workers exposed to older diesel engine exhaust conducted by an Expert Panel appointed by the HEI Board of Directors. In its report, HEI's Diesel Epidemiology Panel concluded that the studies are well prepared and are useful for applying the data to calculate the cancer risk due to exposure to diesel exhaust.

This newsletter reports on the approval of new HEI studies to examine potential health effects of low-level pollution; the completion of a review of diesel exhaust studies (Special Report 19) by an HEI-appointed panel; and WHO's plans to update global air quality guidelines. In addition, it announces the publication of an HEI report taking a closer look at exposure to PM2.5 and its composition and a report evaluating rapid heart rhythm changes after exposure to PM. HEI also announces the recipient of the 2015 Walter A. Rosenblith New Investigator Award and the appointment of three new HEI Research Committee members.
