Fetal Health Negatively Impacted by Airplane Noise
The likelihood of having a low birth weight (LBW) baby is increased if the mother lives close to the airport, in the direction of the runway, and is exposed to noise levels over the 55 dB threshold, a new University of Colorado Denver study found. Results come from a study conducted by Laura Argys, PhD, -
Relative sizes of various allergens
Diagram comparing the sizes of common airborne particles including human hair (50–70 microns), pollen (30–50 microns), ragweed (17–23 microns), dust mite (10 microns), and a 1-micron reference marker. The illustration uses scaled circles to visually represent relative particle sizes, relevant to air quality and filtration contexts. -
What Airports Need to Know About Potential PFAS Liabilities
Learn more about the latest in PFAS regulations and how Jacobs can help in this article. Over the past several years, there has been a surge in regulatory interest to address the public health and environmental risks from releases of per- and polyfluoroalkyl substances (PFAS), including use of aqueous film-forming foams (AFFF) for firefighting or -
Airlines want you to think they’re serious about the climate crisis. They’re not
An offer to plant trees to offset carbon emissions isn’t a solution – it’s a licence to continue with business as usual @wakmax ‘Those dressing up a process that (at best) aims to remove, years from now, carbon emitted today as a climate solution either don’t understand the science, or don’t want you to.’ Photograph: -

Lawmakers want tougher carbon-reduction goals, even as WA falls short of current targets
Citing the latest scientific research, Gov. Jay Inslee is urging legislators to adopt a more aggressive course for curbing emissions. by Shauna Sowersby / January 17, 2020 Piles of wood chips sit near the RockTenn paper mill in Tacoma, June 1, 2016. State measures to limit greenhouse gas emissions from large polluters, including the mill, aren’t -
Installing air filters in classrooms has surprisingly large educational benefits
$1,000 can raise a class’s test scores by as much as cutting class size by a third. By Matthew Yglesias@mattyglesiasmatt@vox.com An emergency situation that turned out to be mostly a false alarm led a lot of schools in Los Angeles to install air filters, and something strange happened: Test scores went up. By a -
2020-01-01Air filters, pollution and student achievement
★A study by NYU economist Michael Gilraine found that installing air filters in classrooms led to a 0.20 standard deviation improvement in math and English test scores, using a natural experiment from the 2015-2016 Aliso Canyon gas leak in Los Angeles. The gas company installed air filters in all schools within five miles of the leak, allowing researchers to compare student achievement between schools that received filters and those that did not. The findings suggest that air filtration is a cost-effective way to boost student achievement by reducing exposure to common indoor air pollutants. -
2019-12-01Mobile ObserVations of Ultrafine Particles: The MOV-UP study report
★ 32The MOV-UP (Mobile ObserVations of Ultrafine Particles) study was a two-year University of Washington research project, funded by the State of Washington, that measured air quality impacts from aircraft traffic on communities living near and beneath the flight paths of Seattle-Tacoma International Airport. Researchers used mobile monitoring methods to collect ultrafine particle data across the affected neighborhoods, working alongside local governments, community members, and an advisory group of agency and city representatives. The findings are intended to inform policymakers and the public about the air pollution risks associated with airport operations in the Seattle-Tacoma region. -
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.
