Air Pollution

This report presents a study led by Marie Pedersen of the University of Copenhagen, Denmark. Pedersen and colleagues examined children’s asthma in four Danish cohorts and focused on exposure to an array of air pollutants, including fine particulate matter, ozone, sulfur dioxide, nitrogen dioxide, and combinations of those pollutants.

New report on air pollution and childhood asthma risk

September 6, 2024

HEI has published a new Research Report, Birth Cohort Studies of Long-Term Exposure to Ambient Air Pollution in Early Life and Development of Asthma in Children and Adolescents from Denmark. The study presented in the report, led by Marie Pedersen of the University of Copenhagen, Denmark, examined children’s asthma in four Danish cohorts and focused on exposure to an array of air pollutants.

This report presents a study that estimated potential health benefits associated with reducing emissions from transportation and other sources at locations across the United States and Canada. Amir Hakami of Carleton University, Canada, and colleagues estimated the improvement in fine particulate matter concentrations and how many fewer deaths would be expected if fine particulate matter, ammonia, nitrogen oxides, and sulfur dioxide emissions were reduced.

This report presents a study that assessed associations between long-term exposure to outdoor ultrafine particles (UFPs) and black carbon with mortality using several modeling approaches. The investigators applied exposure models developed through mobile monitoring in Toronto and Montreal to 1.5 million Canadian adults residing in both cities.

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 (PM_2.5) from 12 µg/m³ (micrograms per cubic meter) to 9 µg/m³. This is the first change in the PM_2.5 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 study examines air pollution’s health impact across Asia

May 31, 2023

Much of what is currently known about the adverse effects of ambient air pollution comes from studies conducted in high-income regions, especially North America and Europe, with relatively low air pollution levels.
