UW study shows Seattle’s historically redlined communities have worse air quality
By Isabella Breda Seattle Times staff reporter As Seattleites awoke to a hazy concoction of wildfire and Fourth of July firework smoke Wednesday morning, a new study dropped, revealing that some neighborhoods in the city are regularly subject to worse air pollution, reflective of historic racist policies. Those neighborhoods, according to research published Wednesday from the University of Washington, -

Environmentalists and industry weigh in on how to decarbonize aviation
By Dominic Gates Seattle Times aerospace reporter Under intense political pressure, the aviation industry has set itself a daunting challenge to decarbonize flying by 2050 and laid out a road map to get there through technological innovation. For environmentalists, especially in Europe, that prolonged switch to clean energy technology is not good enough. “It takes -
2023-05-08Long-term exposure to ultrafine particles and natural and cause-specific mortality
This study examined whether long-term exposure to ultrafine air particles (UFP) is linked to higher death rates among 10.8 million Dutch adults followed from 2013 to 2019. Researchers found that higher UFP exposure was significantly associated with increased risk of natural cause, lung cancer, and respiratory disease mortality, even after accounting for other air pollutants like nitrogen dioxide and fine particles. The findings suggest UFP pose health risks independent of other regulated air pollutants, though this research is unrelated to airport noise policy. -
California becomes the first state to adopt emission rules for trains
April 27, 2023 SACRAMENTO, Calif. — California approved Thursday a first-in-the-nation, ambitious rule limiting rail pollution to aggressively cut greenhouse gas emissions in the state’s latest move to establish itself as a global leader in the fight against climate change. The rule will ban locomotive engines more than 23 years old by 2030 and increase -
Sea-Tac’s legacy of PFAS chemicals: ‘foam showers,’ sick firefighters and contaminated water

2023-01-01Impact of roadside conifers vegetation growth on air pollution mitigation
This study examines how the growth of conifer trees planted alongside roads affects their ability to reduce traffic-related air pollution over time. Researchers found that as conifers grow taller, they become less dense, and the ideal tree height for maximum pollution reduction is between 4 and 6 meters. The findings suggest that regular pruning is essential to maintain roadside vegetation barriers at their most effective size for improving air quality in nearby communities. -
