NBC News | Boxtown, a historic Black neighborhood in South Memphis, is pushing back against Elon Musk’s xAI facility, which locals fear will worsen air pollution due to its methane gas turbines. While city officials tout the tech development as an economic boon, residents — citing a long history of environmental injustice — demand transparency and safeguards, as the Shelby County Health Department considers xAI’s emissions permit.

Healio | A large South Korean study found that higher exposure to particulate matter (PM2.5 and PM10) before COVID-19 hospitalization significantly increased the odds of in-hospital mortality, ICU admission, and mechanical ventilation. Each 1 μg/m³ rise in PM2.5 or PM10 elevated the risks across all age groups, underscoring the need for intensified care for COVID-19 patients from polluted areas.

WDSU | Nearly half of Americans now live in areas with unhealthy air, a sharp increase driven largely by wildfire smoke and climate-related pollution, according to the American Lung Association’s 2025 report. The rollback of environmental protections and inadequate monitoring in most U.S. counties further threaten public health, especially among vulnerable groups like children, older adults, and communities of color.

Statesman Journal | Coffin Butte Landfill’s proposed air quality permit would allow significantly increased emissions of particulate matter while capping greenhouse gases for the first time, as required by updated federal and state regulations. The Oregon DEQ is seeking public input and will hold a virtual hearing on May 20, amid broader scrutiny involving landfill expansion plans, health complaints, and an ongoing EPA investigation into methane leaks.

AZCentral | A series of images spanning nearly two decades captures persistent haze and smog enveloping Phoenix, often worsened by wildfires, temperature inversions, and vehicle emissions. Despite ongoing efforts, the Valley of the Sun continues to struggle with air quality challenges, frequently falling short of EPA ozone standards.

Kingsville Times | A new Ontario-based study published in Epilepsia links long-term exposure to air pollution—specifically fine particulate matter and ozone—to an increased risk of developing epilepsy in adults, marking the first direct epidemiological connection of its kind. Researchers hope these findings will influence environmental policy and improve healthcare planning, particularly in areas with high pollution levels.

Copernicus Atmosphere Monitoring Service (CAMS) | Southeast Asia recorded one of its lowest fire-related emission levels since 2003, despite intense fire activity in March and April affecting air quality in Thailand, Laos, and Vietnam. CAMS monitoring using satellite and modeling data revealed episodes of high smoke concentrations, showing that even a relatively mild fire season can significantly impact regional air quality.

Sustainability Times | A study by Oregon State University found that wildfires intensified by human-driven climate change caused approximately 15,000 deaths and $160 billion in damages in the U.S. from 2006 to 2020, reversing decades of air quality progress. With PM2.5 emissions from wildfire smoke rising and projected to cause 50% more deaths by mid-century, researchers urge immediate climate action, public health protections, and investment in sustainable wildfire management.

University College London | A UCL study analyzing over 9,000 teens from the Millennium Cohort Study found that children exposed to higher levels of air pollution—particularly PM10, PM2.5, and NO₂—during early childhood were significantly more likely to report poor general health at age 17. The research highlighted stark environmental inequalities, with ethnic minority and disadvantaged children disproportionately exposed to polluted areas, emphasizing the urgent need for targeted air quality interventions.

KJCT | Delta County Public Health is advising residents, especially those with asthma or allergies, to take precautions during spring when air quality often worsens due to burning and high winds. Recommendations include staying indoors, using air purifiers, keeping windows closed, and regularly checking air filters and local air quality reports.
