ScienceDirect.com | Researchers used satellite data and machine learning to map nitrogen dioxide, sulfur dioxide, and carbon monoxide levels around schools in Vilnius, Lithuania, revealing that over a third are near major roads and exposed to elevated multi-pollutant air pollution despite limited ground monitoring.

ACS Publications – American Chemical Society | A U.S. Government Accountability Office report outlines the benefits, challenges, and policy options for using lower-cost air quality sensors, highlighting their potential to expand monitoring while stressing the need for better performance standards, guidance, and data quality.

The Cool Down | A new international study reveals that aged desert dust can absorb pollutants and trigger chemical reactions that form harmful secondary organic aerosols, reshaping scientists’ understanding of air pollution sources and impacts.

WIRED | Personal air quality monitors are becoming essential tools for detecting hyperlocal pollution, filling gaps in government monitoring, and empowering communities to respond to health threats from particulate matter and other airborne contaminants.

Illinois.gov | At the 2025 Illinois State Fair, the Illinois EPA’s “Together for Healthier Air!” exhibit will educate visitors of all ages about air quality through interactive games, clean energy displays, and informative resources on ozone, particle pollution, and wildfire smoke.

NPR | Wildfire smoke from Canada is blanketing the Midwest and Northeast U.S., pushing air quality to unhealthy levels and posing serious health risks, especially from fine particles that can inflame lungs and affect the heart, even when the smoke isn’t visible or smells strong.

NBC News | A new study found that using HEPA air purifiers in homes near busy roads reduced systolic blood pressure by nearly 3 points in adults with slightly elevated levels, suggesting a simple way to lower cardiovascular risk from traffic-related air pollution.

ABC News – The Walt Disney Company | Smoke from over 700 Canadian wildfires is triggering air quality alerts across 10 U.S. states, with officials warning of prolonged haze and health risks for sensitive groups in the Northeast.

WCSC | South Carolina upgraded its North Charleston air quality station with new remote-access calibration tools, enhancing monitoring of sulfur and nitrogen dioxide to ensure compliance with EPA clean air standards.

ScienceDirect.com | A study comparing five methods for imputing missing PM2.5 data in Seoul found that Positive Matrix Factorization (PMF) outperformed machine learning and statistical approaches while also revealing spatial pollution patterns across the city.
