Ultrafine particles for dummies
You already know air pollution is bad. But do you know about the tiny particles so small your body can't even detect them — let alone defend against them? Ultrafine particles (UFPs) represent a growing public health concern that most people have never heard of, and the science community hasn't done a great job of explaining why you should care. Unlike larger pollutants your nose and lungs naturally filter out, UFPs — largely produced by jet engines, vehicles, and industrial activity — are so small they slip past every biological defense, entering your bloodstream, lungs, and even your brain. Once they're in, they don't leave. This article breaks down what we know, what we don't, and why the gap between scientific caution and public urgency may be putting lives at risk. -

2025-08-11Impacts of Aviation Emissions on Community Health
Researchers from the University of Washington presented findings to King County's Airport Round Table Advisory Committee showing that aviation emissions pose significant public health risks to nearby communities. Airports account for 70% of airborne lead emissions in King County, primarily from piston-engine aircraft burning leaded aviation gasoline, and multiple studies link living close to such airports with elevated blood lead levels in children. The presentation also highlighted broader health harms from aviation pollutants—including ultrafine particles and nitrogen oxides—affecting neurological, cardiovascular, and respiratory health. -

Centennial Airport is Leading the Way With Unleaded Avgas
Author: Jodi Richards Published in: November-December 2023 In early May, Centennial Airport (APA) in Englewood, CO, became that state’s first airport to offer unleaded aviation gas for piston-engine aircraft. The active general aviation facility is even offsetting associated costs for early adopters who buy the more expensive eco-friendly alternative. Executive Director Mike Fronapfel says that -

2023-05-02Eliminate Aviation Gasoline Lead Emissions Initiative (EAGLE): Aviation Noise & Emissions Symposium presentation
The Eliminate Aviation Gasoline Lead Emissions Initiative (EAGLE) is a coalition of government and industry partners, including the FAA and major aviation associations, working to eliminate lead emissions from aviation gasoline by the end of 2030 without compromising the safety or efficiency of general aviation. The initiative operates through four key pillars: supply chain infrastructure and deployment, research and innovation, unleaded fuel evaluation and authorization, and regulation and policy activities. A presentation on the initiative was delivered at the Aviation Noise & Emissions Symposium at U.C. Davis on May 2, 2023. -
