2024-10-01PSCAA: Update on Our Ongoing Ultrafine Monitoring October 2024
The Puget Sound Clean Air Agency's Monitoring Team provides an October 2024 update on their ongoing ultrafine particle (UFP) monitoring program, explaining that UFPs are extremely tiny particles smaller than 0.1 microns that are not currently regulated under air quality standards. The presentation covers key concepts such as particle number concentration (PNC), monitoring instrumentation, and WHO good practice recommendations for UFP measurement. While not specific to noise policy, this monitoring effort is relevant to understanding air quality impacts near high-traffic areas such as airports. -

Study suggests ultrafine particles linked to 1,100 deaths per year in Montreal and Toronto
Study followed 1.5 million people over 15 years Joe Bongiorno · The Canadian Press · Posted: Aug 07, 2024 3:49 PM PDT | Last Updated: August 7 McGill professor breaks down how vehicle and industry pollution affect our health Duration 4:46 Scott Weichenthal is with McGill University’s department of epidemiology and biostatistics, and is the -
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 -
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. -
Airport workers asking Sacramento to mandate airlines report jet fuel emissions
Sid Garcia Wednesday, June 5, 2024 12:57PM A new study has detailed the health effects of jet fuel emissions on airport workers and people living near an airport or flight path.

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, -
2023-08-23SeaTac International Airport: Trifecta for change
This presentation addresses environmental and health concerns surrounding Seattle-Tacoma International Airport, framing the issue as more than a mere noise nuisance by highlighting the health impacts of Jet A fuel pollution, specifically ultrafine particles. It outlines a 'Trifecta for Change' strategy that includes shifting public dialogue, engaging the University of Washington to study pollution prevalence, and building local, state, and federal partnerships to advance mitigation efforts. -
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 -

2023-07-10Supplemental material: Exposure disparities by income, race and ethnicity, and historic redlining grade in the greater Seattle area for ultrafine particles and other air pollutants
This environmental health study examines how exposure to ultrafine particles and other air pollutants varies across the greater Seattle area based on income, race and ethnicity, and historical redlining grades assigned by the Home Owners' Loan Corporation (HOLC). Researchers analyzed pollutant concentration data from 2019-2020 alongside census and demographic data to identify disparities between communities. The supplemental materials include statistical tables and scatterplots supporting the main findings on environmental inequality across Seattle neighborhoods.
