Robust scientific evidence supports EPA’s new air quality standard to improve public health

February 13, 2024

HEI acknowledges the decision by the U.S. Environmental Protection Agency to lower the National Ambient Air Quality Standards (NAAQS) for fine particulate matter air pollution (PM2.5) from 12 µg/m3 (micrograms per cubic meter) to 9 µg/m3. This is the first change in the PM2.5 NAAQS limits since 2012. The EPA has estimated that their decision to lower the limit may prevent as many as 4,500 premature deaths in the U.S., including many from historically marginalized and other vulnerable communities that often face the greatest risks from air pollution exposure.

New Canadian study reports health effects at very low air pollution levels

July 13, 2022

A comprehensive new HEI study examining potential health risks from low levels of air pollution exposure in millions of Canadian citizens reports increased risks of mortality, including at the lowest levels of exposure to fine particulate matter air pollution (PM2.5), levels tha

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.

Special Report 23
Health Effects Institute

This comprehensive scientific review examines the evidence for associations between several adverse health effects and traffic-related air pollution (TRAP). The review, the largest of its type to date, was conducted by a panel of 13 renowned experts who evaluated 353 published scientific reports on traffic pollution and related health effects between 1980 and 2019.
