Healio | A new analysis using the Asthma Equity Explorer Database reveals a positive, though weak, correlation between PM2.5 levels and asthma prevalence across San Francisco census tracts, with southeastern areas showing the highest concern. The findings highlight the health risks of wildfire smoke and air pollution and support data-driven interventions, personalized care, and stronger air quality regulations.

Chronogram Magazine | Bard College and startup JustAir have launched a new real-time air quality monitoring platform for the Hudson Valley, featuring hyperlocal data from stations in Kingston, Poughkeepsie, Red Hook, and Newburgh. The system empowers residents with alerts and health guidance, marking a major step in regional environmental monitoring and public health protection.

Richmond Standard | Chevron Richmond and the Bay Area Air District have reached an agreement to upgrade air monitoring by adding high-accuracy hydrogen sulfide sensors, expanding public data access, and issuing quarterly pollutant reports. The deal aims to improve transparency and community engagement, setting a new standard for refinery air quality monitoring in the region.

Fox 59 | Indianapolis has issued its first Knozone Action Day of 2025 due to elevated ground-level ozone, posing health risks for vulnerable groups like children, seniors, and those with respiratory or heart conditions. Residents are urged to limit outdoor activity and reduce ozone-contributing behaviors to help improve air quality.

The Washington Post | Wildfire smoke from British Columbia is spreading across central and eastern U.S. states, creating unhealthy air quality conditions from Montana to the Northeast and contributing to near-record smoke levels for June. The high-pressure system over the East Coast is trapping smoke near the ground, while transatlantic smoke has also reached parts of Europe and Russia.

The Guardian | The EPA under the Trump administration has proposed repealing key climate and air toxics rules, allowing power plants to emit more greenhouse gases and hazardous pollutants like mercury. Critics warn the move endangers public health, reverses environmental progress, and prioritizes fossil fuel interests over scientific and legal mandates.

CBS News | The EPA has announced plans to repeal Biden-era limits on carbon dioxide and mercury emissions from fossil fuel power plants, despite projections that the rules would prevent thousands of deaths and billions in health costs. Critics warn the rollback defies scientific consensus and endangers public health, while environmental groups prepare legal challenges.

NBC News | The EPA has proposed eliminating carbon and mercury pollution limits on power plants, reversing Biden-era rules aimed at reducing emissions and protecting public health. Critics warn the move prioritizes fossil fuel interests over climate action and legal obligations, risking increased pollution and public health harms.

Clean Air Task Force | The EPA has proposed repealing two major air pollution rules: strengthened mercury and air toxics standards and carbon limits on coal and gas power plants, risking increased emissions of hazardous pollutants and climate-harming gases. Critics argue the rollback defies scientific evidence and legal obligations, threatening public health and disproportionately harming vulnerable communities.

Earthjustice | The Trump administration’s EPA has proposed repealing key air pollution standards, including limits on mercury, arsenic, and carbon emissions from power plants, reversing significant public health and climate protections. Critics warn the rollback prioritizes fossil fuel interests over community health, particularly affecting vulnerable populations near polluting facilities.
