  • 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

  • The toxic killers in our air too small to see

    Current pollution meters don’t count the very smallest pollutants – nanoparticles. Recent research suggests these tiny toxic substances could be a major cause of illness and death. By Tim Smedley 15th November 2019 A After years of headlines about air pollution, we’ve been misled on a few things about the world’s biggest environmental health problem.

  • Aviation-Related Impacts on Ultrafine Particle Number Concentrations Outside and Inside Residences near an Airport

    Jet engine exhaust is a significant source of ultrafine particles and aviation-related emissions can adversely impact air quality over large areas surrounding airports. We investigated outdoor and indoor ultrafine particle number concentrations (PNC) from 16 residences located in two study areas in the greater Boston metropolitan area (MA, USA) for evidence of aviation-related impacts.
