NPR | The Trump administration is seeking to repeal the EPA’s 2009 endangerment finding that underpins U.S. climate regulations, a move critics say prioritizes fossil fuel interests over science and public health while setting the stage for a long legal battle.

Appalachian Voices | Residents of Institute, West Virginia — a historically Black community long exposed to industrial pollution from nearby chemical plants — are turning to grassroots air monitoring networks and environmental advocacy to fight for accountability, public health, and environmental justice amid continued resistance from industry and lawmakers.

Newsroom | UCLA | UCLA researchers have launched a new air quality monitoring network across West Los Angeles to track both fine and coarse pollutants stirred up by wildfire recovery and reconstruction, offering real-time data to help protect residents and workers.

ScienceDirect.com | A study in Delhi found that indoor air pollution, especially ultrafine particle concentrations, significantly increases during festival activities like fireworks and cooking, posing heightened health risks due to toxic particles ranging from 10 to 1000 nanometers in size.

Los Angeles Times | UCLA researchers have deployed a new network of real-time air pollution monitors across northwest Los Angeles County to track fine and coarse particulate matter from wildfire recovery and construction, aiming to provide residents with hyperlocal data to make informed health decisions.

The Conversation | A study found that natural gas pipeline leaks, including small and undocumented ones, significantly contribute to regional air pollution and health risks by increasing fine particulate matter (PM2.5), underscoring the need for stricter leak prevention and faster response to protect both the climate and public health.

News-Medical.net | A study by NYU researchers found that shutting down a major fossil fuel plant near Pittsburgh led to immediate and sustained reductions in respiratory-related emergency visits, especially among children, highlighting the significant health benefits of reducing industrial air pollution.

ABC13 | Air Alliance Houston has launched an online dashboard with low-cost air sensors in pollution-prone neighborhoods to help residents monitor local air quality and make informed decisions about outdoor activities, especially for those with respiratory conditions.

The Columbus Dispatch | An air quality alert has been issued for central Ohio on July 23 due to expected unhealthy ozone levels for sensitive groups, driven by high temperatures, stagnant air, and lingering smoke.
