2024-06-26Airborne nanoparticle concentrations are associated with increased mortality risk in Canada’s two largest cities
A Canadian research study found that exposure to airborne nanoparticles is linked to higher mortality risk in Toronto and Montreal. The study, published in 2024 and funded by the Health Effects Institute, analyzed particle concentration data across Canada's two largest cities to assess long-term health impacts. While focused on urban air quality in Canada, the findings contribute to broader scientific understanding of how fine airborne particles from traffic and other sources affect public health. -

Relative sizes of various allergens
Diagram comparing the sizes of common airborne particles including human hair (50–70 microns), pollen (30–50 microns), ragweed (17–23 microns), dust mite (10 microns), and a 1-micron reference marker. The illustration uses scaled circles to visually represent relative particle sizes, relevant to air quality and filtration contexts. -
2019-04-17Estimated long-term (1981−2016) concentrations of ambient fine particulate matter across North America from chemical transport modeling, satellite remote sensing, and ground-based measurements
Researchers estimated historical fine particulate matter (PM2.5) air pollution levels across North America from 1981 to 2016 by combining satellite data, computer modeling, and ground-based measurements. The study found that average PM2.5 concentrations fell dramatically over the period, dropping from 22 μg per cubic meter in 1981 to about 7.9 μg per cubic meter in 2016. While this research focuses on air quality rather than airport noise, it provides a scientific framework for tracking long-term environmental exposure trends relevant to public health policy. -
2017-05-11Modeling variability in air pollution-related health damages from individual airport emissions
Researchers used advanced air quality modeling to estimate the health impacts of emissions from 66 U.S. airports, including how pollution from each individual airport contributes to premature deaths. The study found wide variation in health damage across airports, driven largely by nearby population density and local atmospheric conditions. These findings can help inform emissions control policies at specific airports to better protect public health.
