The Kathmandu Post | Kathmandu’s air quality crisis—driven by vehicle emissions, construction dust, and forest fires—is costing Nepal up to $4 billion annually and cutting citizens’ life expectancy by years. A proposed shift toward treating clean air as a national economic and health priority includes forming a Clean Air Task Force, launching green transport bonds, and piloting emissions trading systems to combat what experts call Nepal’s “billion-dollar smog.”

The Guardian | The Miami Grand Prix has become a billion-dollar spectacle of celebrity and speed, but its placement in the predominantly Black, working-class community of Miami Gardens has raised lasting concerns about environmental justice and displacement. While lawsuits over noise and air pollution have failed to gain traction, critics argue the event reflects a broader pattern of pushing disruptive developments into communities with the least political power to resist.

BBC | Surrey has launched its first School Street scheme near Farnham Heath End School, restricting vehicle access on Bullers Road during peak hours to cut air pollution and improve safety. The initiative is part of a £3 million county-wide investment, with more schemes planned for other schools.

ScienceDirect.com | Researchers have developed innovative calixarene-based cryopolymers that can both detect and remove pollutants from air and water, addressing a major gap in current remediation technologies. These porous materials operate via dual absorption mechanisms and visibly detect airborne NO₂, offering a multifunctional platform for environmental cleanup.

EurekAlert! | A CMAJ study found that Ontario saw a significant spike—up to 24%—in asthma-related emergency visits following early June 2023 wildfire smoke, though a second episode later that month had no similar effect. Researchers suggest protective medications and behavioral adaptations may have helped, while experts urge Canada to adopt consistent strategies to reduce smoke exposure as wildfires grow more frequent and severe.

CMAJ | Decades of top-down air pollution regulations have improved public health, but wildfire smoke—uncontrollable at its source—is now emerging as a major, unregulated threat. As evidence mounts linking wildfire smoke to a wide range of acute and chronic health harms, experts call for policy-driven solutions like indoor air standards and worker protections to reduce exposure and mitigate long-term health impacts.

Space | Scientists aboard a jet tracked the fiery reentry of ESA’s Salsa satellite, capturing rare data on the atmospheric breakup and chemical emissions of space debris. The findings revealed elements like lithium, potassium, and aluminum, offering early insights into how satellite burn-ups may contribute to long-term air pollution and ozone depletion.

The New Indian Express | Delhi is preparing to trial cloud-seeding as a potential pollution control and rain-enhancement method, with IIT-Kanpur tasked to execute the plan if approved. The ₹1.5 crore-per-trial project aims to test whether artificial rainfall can help reduce air pollution, pending clearances from 13 regulatory agencies.

probashirdiganta.com | Dhaka, the capital of Bangladesh, was ranked as the world’s second most polluted city in terms of air quality, according to IQAir data . The city’s Air Quality Index (AQI) reached hazardous levels, reflecting severe health risks for its over 20 million residents.

CMAJ | Ontario’s record wildfire smoke in June 2023 triggered a sharp rise in asthma-related emergency visits—peaking at 24% above normal—particularly among adults and children. Despite worse air quality later that month, the initial smoke episode had a stronger health impact, highlighting how timing and prior exposure can influence respiratory outcomes.
