2025-10-03Tufts University Researcher Reports High Air Pollution in Hanscom-Area Towns
Hanscom Field. JENNY STEWART PHOTO This story has been changed to reflect that the air quality study has been published and is available. A recent research project regarding air quality impacts in the four towns that border Hanscom Field found that there is a high concentration of ultrafine particles (UFP) and airborne lead.

Puget Sound Clean Air activates North Sea-Tac Air Quality Monitoring Station
Take a tour of the first fixed-site UFP system near Sea-Tac Airport Puget Sound Clean Air Agency (PSCAA) recently activated the first fixed site air quality monitoring station near Sea-Tac Airport designed to monitor aviation emissions. As of this week it is now on-line and providing data! The station is the twin of a site -
2025-01-12UWDEOHS: Assessing Exposures to Source-specific Air Pollution through a Multi-pollutant Mobile Monitoring Campaign in Seattle, WA
This is the first study to combine a one-year mobile monitoring campaign with PMF (Positive Matrix Factorization) analysis to simultaneously estimate source-specific air pollution exposures and emission factors of different vehicle types. This methodology can be extended to other metropolitan areas. -

2024-08-05Ultrafine particles linked to over 1,000 deaths per year in Canada’s two largest cities
A first-of-its kind study conducted in Canada’s two largest cities by McGill-led researchers has linked about 1,100 premature deaths per year to an unregulated air pollutant. Ultrafine particles (UFPs) primarily come from vehicle emissions and industrial activities. Canada’s federal and provincial governments have not set concentration limits for UFPs, as they have for larger fine -

Researcher Probes Ultrafine Particles’ Ties to Airfield Activity
Researchers have identified concentrations of ultrafine particles in Bedford neighborhoods that may be connected to aircraft operations at Hanscom Field. Dr. Neelakshi Hudda, a research assistant professor in civil and environmental engineering at Tufts University, shared preliminary findings at a virtual meeting of the Hanscom Field Advisory Commission on Tuesday. The health implications are uncertain, -

Beautiful Sunsets vs. Particulate Matter
Limit your exposure to particulate matter. Limit your cumulative risk. The smoke from wildfires has once again blanketed the areas around Sea-Tac Airport, creating PM2.5 air quality readings often seen more in Third World countries. Unfortunately, most of us are highly biased to only perceive dangers we can see. For example, many of you will
