Ultrafine 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

Study shows traffic-related air pollution in Irvine weakens brain function

Anna Aldrich, University of California, Irvine The brains of wild type (WT) and Alzheimer’s (APP) mouse models were analyzed after exposure to purified air (Con) and ultrafine particulate matter (PM) for the presence of astrocyte cells. These were visualized by staining them green (left column), with potentially harmful and activated astrocytes appearing in red (middle

*Where’s my Clair Patterson?

There is this form of air pollution, which you probably have not heard of, called ultrafine particulates (UFPs). Though they are invisible, they seem to have some particularly nasty effects on human health. UFPs have not been well-studied, they are unregulated, and yet they are prevalent in commercial jet engine emissions. But this is not
