Newsweek | The EPA urged residents in parts of Arizona to stay indoors after PM2.5 pollution reached unhealthy levels, warning of elevated health risks, especially for children, older adults, and people with heart or lung conditions.

RRSpin | North Carolina reports sharp, decades-long declines in air pollutant emissions and improved air quality statewide, with most pollutants now well below federal health standards despite continued population and economic growth.

How-To Geek | A home automation enthusiast describes how integrating an air quality monitor with Home Assistant enables alerts and smart responses to PM2.5, humidity, and VOC levels, improving indoor air management and comfort.

Envirotech Online | The EPA has launched a Clean Air Act resource for data centres that clarifies existing permitting and modelling rules, signalling faster, precedent-based approvals for generator-driven emissions without strengthening monitoring requirements or addressing cumulative air quality impacts.

The World Economic Forum | A new analysis argues that modest investments in air quality data and local leadership could deliver outsized economic and health returns in high-burden countries, where air pollution costs about 6% of global GDP but remains vastly underfunded and under-monitored.

OANANews | Ho Chi Minh City plans a major expansion of its environmental monitoring network in 2026 to address worsening air, water, and land pollution pressures as it grows toward megacity status, adding hundreds of new monitoring stations across the city.

Los Angeles Times | More than two months after a Chevron refinery explosion in El Segundo, regulators and the company have yet to disclose the cause or full pollution impacts, raising concerns about delayed investigations, repeated flaring incidents, and whether air monitoring systems functioned properly during the fire.

Senator Steve Padilla – CA.gov | California Senator Steve Padilla announced plans to update the state’s decades-old hydrogen sulfide air quality standard through SB 58, citing new scientific evidence and severe health impacts in communities near the Tijuana River Valley and Salton Sea that are currently unprotected by outdated regulations.

Nature | A study of 276 Chinese cities found that extreme heat and heatwaves significantly worsen river organic pollution and water scarcity, underscoring the need to incorporate temperature-driven risks into future water quality and river management policies.

World Bank | A new report outlines a coordinated roadmap to cut PM2.5 pollution by more than half across the Indo-Gangetic Plains and Himalayan Foothills by 2035 through targeted emission reductions, health protections, and strengthened regional institutions.
