Pulmonology Advisor | A retrospective study of over 2,700 patients in China and Belgium found that long-term exposure to air pollutants like PM2.5, PM10, SO₂, and NO₂ was significantly associated with a lower risk of type 2 chronic rhinosinusitis with nasal polyps (CRSwNP), while allergen sensitization was linked to increased risk. Despite declining pollution levels, the prevalence of type 2 CRSwNP rose over time, emphasizing the complex interplay between environmental and immunological factors in disease pathogenesis.

Clinical Trials Arena | Diagnosed cases of Parkinson’s disease in the U.S. are projected to rise from 1.03 million in 2025 to over 1.23 million by 2033, according to GlobalData. A recent study in JAMA Network Open found that while genetic factors pose the strongest risk, exposure to traffic-related air pollution also increases the likelihood of Parkinson’s onset—especially when combined with genetic predisposition.

California Air Resources Board – CA.gov | The California Air Resources Board (CARB) has awarded a record $20.9 million to 51 projects through its Community Air Grants program, supporting local efforts to monitor and reduce air pollution in some of the state’s most impacted areas. Funded by cap-and-trade dollars, the grants empower 43 community organizations and four Tribes to implement air monitoring, education, and justice initiatives that align with CARB’s goals for environmental equity and public health.

ScienceDirect.com | This special issue explores the roles of atmospheric aerosols in both urban and rural settings, focusing on their optical, physical, and chemical properties and their impacts on air quality and climate change—especially in sensitive and high-emission regions. It emphasizes the importance of understanding aerosol sources, aerosol-radiation-cloud interactions, and the transport of toxic elements to inform sustainable development and climate policy.

NRDC | Community advocates in Albuquerque successfully pushed for the Health, Environment, and Equity Impacts (HEEI) Rule, requiring air permit applicants to account for the cumulative impact of pollution on already overburdened neighborhoods. Now under industry challenge, the rule is being defended as a vital tool for environmental justice, recognizing that pollution’s effects are worsened by social and economic vulnerability.

Nature | A study of over 1.3 million births in North Carolina found that both average levels and repeated exceedances of ozone (O₃) and fine particulate matter (PM2.5) during pregnancy were associated with varying risks of preterm birth. The research highlights how using different air pollution metrics—average vs. threshold exceedances—can reveal distinct risk patterns, offering insights relevant to future air quality standards and maternal health policy.

EquiManagement | A new study analyzing over 31,000 Thoroughbred races in California found that even low levels of fine particulate matter (PM2.5)—below current U.S. air quality standards—negatively impacted racehorse speed. The findings suggest current air quality guidelines may not sufficiently protect equine athletes, prompting calls for more cautious training and racing practices during pollution events.

Newsweek | Tourists at Big Bend National Park were advised of unhealthy air quality levels on Tuesday, as EPA’s AirNow map indicated pollution levels in the “unhealthy for sensitive groups” range (AQI 101–150). The warning emphasized heightened health risks for children, older adults, and people with respiratory conditions due to elevated particulate matter or ozone in the region.

Times of India | Indoor air pollution in India poses a significant yet often overlooked threat to respiratory health, with indoor air quality potentially up to ten times worse than outdoor air due to allergens like dust mites, pet dander, and volatile organic compounds (VOCs) . Asthma affects over 30 million people in the country, accounting for nearly half of all asthma-related deaths worldwide, underscoring the urgent need for improved indoor air quality through better cleaning practices and increased public awareness.
