EurekAlert! | A new study using a custom-built drone with low-cost sensors found unexpectedly high PM2.5 concentrations up to 100 metres above Delhi, revealing that current models may underestimate urban haze levels and offering a scalable tool to improve air pollution forecasting and mitigation.

TechCrunch | The Trump administration’s EPA is reportedly preparing to repeal the 2009 “endangerment finding” that underpins federal greenhouse gas regulations, a move likely to trigger lawsuits, reshape U.S. climate policy, and create regulatory uncertainty for industries such as automakers.

Newsweek | Air quality alerts were issued for parts of Alaska, Pennsylvania, and Alabama on February 10 after PM2.5 levels reached “unhealthy” categories, prompting officials to advise residents to limit outdoor activity and reduce exposure to hazardous fine particle pollution.

U.S. News & World Report | A new study finds that living in neighborhoods with high levels of particle air pollution raises health risk by 48%, with combined exposure to damp housing and polluted air further compounding the danger.

Daily Mail | Air quality alerts were issued across parts of Pennsylvania, Georgia, Alabama, and Oklahoma after wildfire smoke and high-pressure stagnant air drove PM2.5 levels into “unhealthy” ranges, prompting officials to urge residents to stay indoors and limit exposure.

ScienceDirect.com | By integrating GEMS satellite data with ground monitoring, meteorological, and geographic information, researchers developed a multi-output CatBoost model that accurately predicts hourly concentrations of six major air pollutants across Taiwan, offering a scalable tool for real-time air quality surveillance and public health risk assessment.

Yale School of Public Health – Yale University | A Yale-led study finds that while U.S. PM2.5-related cardiovascular deaths fell nearly 45% from 2001 to 2020, remaining mortality is increasingly driven by specific pollution components like black carbon and disproportionately burdens Black and Hispanic communities, highlighting the need for more targeted and equitable air quality policies.
