  Atmosphere 2022: UWDEOHS Healthy Air, Healthy Schools

  A study examining the effectiveness of portable HEPA filters in reducing ultrafine particles (UFPs) from aircraft and traffic sources in five schools near Sea-Tac International Airport. The research found that HEPA cleaners significantly reduced indoor UFP concentrations to one-half to one-tenth of outdoor levels. Atmosphere 2022: https://www.mdpi.com/2073-4433/13/10/1623

  Community health and airport operations related noise and air pollution: Report to the legislature in response to Washington State House Bill 1109

  This December 2020 report, prepared by Public Health Seattle & King County in response to Washington State House Bill 1109, examines how noise and air pollution from airport operations affect the health of communities near Sea-Tac Airport compared to the rest of King County. It reviews evidence on pollutants such as ultrafine particulates, their links to conditions like asthma, heart disease, and reduced life expectancy, and includes findings from a University of Washington study on air quality. The report concludes with recommendations for addressing these public health impacts.

  Projecting the health and economic burden of aircraft noise

  This study projects the long-term health and economic costs of aircraft noise generated by the NextGen automated flight system, focusing on communities near Baltimore Washington International Airport. Using a mathematical simulation model, researchers estimated the impact of noise exposure on cardiovascular disease, anxiety, annoyance, and low birth weight over periods of 10, 20, and 30 years. The findings are intended to inform noise mitigation policies and provide a clearer picture of the public health consequences of modern air traffic management systems.

  The Flight Plan Project Final Environmental Impact Statement

  The Flight Plan Project, a joint effort by the Puget Sound Regional Council and the Port of Seattle, produced this 1992 Final Environmental Impact Statement to evaluate long-term commercial air transportation options for the central Puget Sound region. It examines system-level alternatives ranging from expanding Sea-Tac Airport to building new airport facilities, assessing trade-offs related to noise, air quality, land use, and regional quality of life. The document serves as a programmatic planning tool, with no single preferred alternative identified, intended to guide future site-specific environmental reviews and regional airport policy decisions.

  The health effects of ultrafine particles

  Review article by Dean E. Schraufnagel published in Experimental & Molecular Medicine (2020) 52:311–317, DOI 10.1038/s12276-020-0403-3, examining the health effects of ultrafine particles (PM0.1, also called nanoparticles). Covers PM0.1 sources (traffic exhaust, welding, forest fires, cooking, tobacco smoke), absorption and retention in the lung, translocation to distal organs, pulmonary inflammation, metal fume fever, cardiovascular disease,
