The projects are focused on enhancing air quality monitoring in communities across the U.S. in areas that are underserved, historically marginalized and overburdened by pollution, supporting President Biden’s Justice40 Initiative.
Networks of low-cost air quality sensors are able to detect temporary peaks and “hot spots” in air pollution and could be a better tool for tracking short-term changes in air quality in communities than regulatory sensors. Monitoring fine-scale, real-time changes in air pollution could support efforts to protect public health.
Higher exposure to a certain type of traffic-related air pollution called particulate matter may be linked to an increased risk of dementia, according to a meta-analysis published in the October 26, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers specifically looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air. The meta-analysis included all available studies on air pollution and risk of dementia.

For the first time, a University of Washington led team has uncovered that people living in China who have a higher socioeconomic status are actually more exposed to outdoor air pollution, also known as ambient air pollution. This finding runs contrary to existing studies conducted throughout North America, which have shown that higher pollution levels tend to be experienced among people with lower socioeconomic status.

Living in areas with higher air pollution is associated with an increased risk of in-hospital death from stroke, and the risk varies depending on the size of the air pollution particles, according to a new study published in the May 25, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.
An update to The Lancet Commission on Pollution and Health reveals that there were nine million deaths attributable to pollution in 2019 (equivalent to one in six deaths worldwide), the same number as in 2015.
A combination of atmospheric measurements and fine-scale simulations has improved understanding of the modeling anomalies that arise when the model resolution approximates the length scale of turbulence features — an atmospheric simulation problem known as Terra Incognita.
In Chaos, researchers in China created a network model drawn from the traffic index and air quality index of 21 cities across six regions in their country to quantify how traffic emissions from one city affect another. They leveraged data from COVID-19 lockdown procedures to better explain the relationship between traffic and air pollution and turned to a weighted climate network framework to model each city as a node using data from 2019 and 2020. They added a two-layer network that incorporated different regions, lockdown stages, and outbreak levels.
Scientists have identified a mechanism that explains how fine air pollution particles might cause lung cancer, according to a study published today in eLife.
The rates of death and health burdens associated with air pollution are borne unequally and inequitably by people of color and those with lower household income and educational attainment in Washington, D.C., according to a new study.
Over the past few decades, the annual average temperature in the Arctic has increased almost twice as fast as it has elsewhere in the world.

A new GW study of COVID-19 shutdowns in the United States reveals pronounced disparities in air pollution — with disenfranchised, minority neighborhoods still experiencing more exposure to a harmful air pollutant compared to wealthier, white communities.
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.
Companies like Purple Air and IQAir, with air pollution sensors that cost under $300, have brought air quality monitoring to the masses. But when Lawrence Berkeley National Laboratory scientist Tom Kirchstetter looked at Purple Air’s map last year during wildfire season, he noticed a big hole in Richmond, a city of 110,000 to the north of Berkeley.
