In Biophysics Reviews, researchers review recent scientific literature about the effects of particle contaminants on the mucosal system, an internal membrane that serves as the body’s lubricant and the first line of defense from infections and toxins. These data establish a clear link between exposure to airborne or waterborne particulate matter and several health conditions.

Throughout the pandemic, air sensors watched during lockdowns as air pollution fell in residential and commercial areas, and then as pollution rose again with reopenings. The changing levels, the researchers found, which behaved differently in residential and commercial parts of the city, show where pollution is coming from and how it might change in the future under different policies.
During the COVID-19 pandemic, Johns Hopkins Medicine Media Relations is focused on disseminating current, accurate and useful information to the public via the media. As part of that effort, we are distributing our “COVID-19 Tip Sheet: Story Ideas from Johns Hopkins” every other Wednesday.
Researchers reporting in ACS’ Environmental Science & Technology have estimated that, although so-called environmentally friendly fireworks emit 15–65% less particulate matter than traditional fireworks, they still significantly deteriorate air quality.
The broad introduction of particle filters reduced the emission of combustion generated fine and ultrafine particles significantly. As a result, brake disc and tire abrasion are moving into the focus of public health experts and engineers, given their health harming potential. There is still a major challenge, though: How can the quantity and size of brake dust particles be measured correctly? Empa researchers are currently developing a sophisticated method.
Living near an abundance of green vegetation can offset the negative effects of air pollution on blood vessel health. The first-of-its-kind study is published ahead of print in the American Journal of Physiology-Heart and Circulatory Physiology.
To address PPE shortages during the pandemic, scientists at Berkeley Lab and UC Berkeley are developing a rechargeable, reusable, anti-COVID N95 mask and a 3D-printable silicon-cast mask mold.
More frequent exposure to air pollution spikes were associated with reduced test scores for third graders in Salt Lake County. Schools with a higher proportion of students of color and from households experiencing poverty were exposed to more peak pollution days than were schools serving middle- to upper- class and predominately white students.
In Salt Lake City schools, absences rise when the air quality worsens, and it’s not just in times of high pollution or “red” air quality days—even days following lower levels of pollutions saw increased absences.
Salt Lake County, Utah’s air pollution is at times the worst in the United States. Underserved neighborhoods—and their schools—experience the highest concentrations. A new study utilized nearly 200 PM 2.5 sensors through the Air Quality and U network and revealed persistent social inequalities in Salt Lake County schools.
Mechanical engineering’s Matthew Rau will study ocean particulate matter, with the hopes of adding to the knowledge surrounding carbon dioxide absorption
On Tuesday, April 14, the US Environmental Protection Agency announced it would decline to impose stricter controls on particulate matter emissions, which are known to cause health problems and premature death. The current standard, enacted in 2012, limits the amount…
Researchers report in Environmental Science & Technology Letters that particles with diameters less than 1 μm (PM1) are more strongly correlated with cardiovascular disease.
