Meeting agenda for University of Washington advisory group focused on urban ultrafine particles research. The 3-hour meeting covers partner updates, UW research highlights, policy landscape review, regional monitoring enhancements, and open forum discussion to address knowledge gaps from the MOV-UP study.

A comprehensive study measuring ultrafine particles, lead, and other air pollutants from aviation emissions at Hanscom Field across four surrounding Massachusetts towns. The study found that UFP concentrations were up to two-fold higher at downwind sites and often exceeded WHO guidelines, with the highest impacts in Bedford and Lexington.

A scientific study examining the association between long-term exposure to ultrafine particles (UFP) and mortality in the Netherlands. The study followed 10.8 million adults from 2013-2019 and found significant associations between UFP exposure and natural, cardiovascular, respiratory, and lung cancer mortality.

Academic paper presented at the 183rd Meeting of the Acoustical Society of America arguing that the FAA’s 65 dBA day-night average sound level standard is not safe for public health. The paper discusses how the EPA calculated safer levels at 55 dB for outdoor activities and 45 dB for indoor activities, and examines the non-auditory

A comprehensive review examining the cardiovascular health impacts of traffic noise exposure, with particular emphasis on nighttime noise effects. The study discusses WHO guidelines, mechanistic pathways involving oxidative stress and vascular dysfunction, and epidemiological evidence linking noise exposure to heart disease, stroke, and other cardiometabolic conditions.

This paper examines environmental justice requirements, best practices, and challenges facing federal agencies since Executive Order 12898. It explores the gap in EJ implementation after the order’s issuance, analyzes case studies from Porter Ranch and Flint, and proposes stopgap measures for consistent federal EJ compliance.

Academic review paper examining perception of low frequency noise and infrasound, including human responses, measurement challenges, and the historical misconceptions that have created public fear around these sound phenomena. The paper addresses hearing thresholds, sensitivity variations, and unexplained complaints of low frequency noise.
