CBS News | The Senate has voted 52–46 to overturn an EPA rule requiring major industrial polluters to permanently maintain strict controls on seven highly toxic air pollutants, marking an unprecedented rollback of the Clean Air Act. Critics warn the move endangers public health by allowing facilities to reduce pollution controls over time, while supporters claim it incentivizes innovation and regulatory flexibility.

Electropages | Panasonic’s new SN-GCQB1 laser-type air quality sensor, now available from Mouser Electronics, offers precise monitoring of temperature, humidity, particulate matter, VOCs, and eCO2 for both indoor and outdoor environments. With features like a laser diode, onboard MPU, auto-calibration, and electromagnetic shielding, the compact sensor is suited for smart buildings, HVAC systems, and portable air monitoring devices.

Kentucky Lantern | Louisville’s air regulator plans to challenge the EPA’s termination of a $1 million environmental justice grant meant to fund air toxics monitoring near the Rubbertown industrial area. The canceled study aimed to assess health impacts from pollution in West Louisville—where residents face stark disparities in air quality and life expectancy—by involving researchers, health centers, and community groups in data collection and public health response.

Commonwealth of Pennsylvania | The Pennsylvania DEP has launched the nation’s most intensive air monitoring study of unconventional gas wells, gaining full access to a CNX site to track emissions through every stage of development. This multi-year initiative, part of a broader transparency effort by the Shapiro administration, aims to generate real-time data on VOCs and PM2.5 to inform public health protections and future energy policies.

IIASA PURE | A new study using European health and environmental data finds that exposure to PM2.5 and PM10 significantly impairs cognitive performance in older adults, with effects varying by education level and gender. The research underscores the urgent need for air quality policies that consider environmental impacts on aging populations, particularly women with lower educational attainment.

USGBC | A new white paper by GBCI India and Hollingsworth & Vose highlights how advanced filter media can maintain high indoor air quality in polluted regions without significantly increasing HVAC energy use. The research emphasizes the importance of balancing filtration efficiency and pressure drop to ensure both occupant health and sustainable building performance.

GlobeNewswire | Camfil USA has announced “Air Quality Week,” a five-day educational campaign running May 5–9 to raise awareness about the health and environmental impacts of air pollution. With daily themes ranging from wildfire smoke to indoor pollutants and ecosystem effects, the initiative offers science-based resources for schools, healthcare, industry, and the public through freely accessible content.

Cureus | Improving indoor air quality in schools through enhanced ventilation and monitoring can significantly reduce asthma-related absences and improve cognitive performance among students. Research highlights the effectiveness of strategies like HEPA filtration and outdoor air exchange, urging policymakers to adopt scalable, evidence-based interventions for healthier learning environments.

BridgeDetroit | Residents in Southwest Detroit reported hazardous odors near Marathon Petroleum, with air monitors detecting elevated sulfur levels despite no confirmed violations or releases from the refinery. The incident underscores the region’s persistent air quality issues tied to multiple industrial sources, prompting renewed calls for vigilance and public reporting.

Forbes | The American Lung Association’s latest “State of the Air” report finds that nearly half of Americans are now exposed to harmful air pollution, driven by increasing ozone levels and fine particulate matter linked to climate change. Despite decades of progress under the Clean Air Act, rising wildfire activity, extreme heat, and recent policy rollbacks are threatening hard-won public health gains.
