The piece argues that dust storms—historically deadly 'Dust Bowl' events—are returning to the US as hotter, drier conditions and waning vegetation lift dust into the sky, with health risks ranging from dust pneumonia to Valley Fever; it cites 2025 events in El Paso and New Mexico and warns that climate change could make such 'deathstorms' more frequent and costly unless mitigation and forecasting improve.
Los Angeles firefighters are assisting Ventura County with the Sandy Fire in Simi Valley, a fast-moving brush blaze now estimated at 1,364 acres and moving east. Smoke may drift into the San Fernando Valley, potentially affecting air quality. An evacuation warning is in place for portions of West Hills and Chatsworth. LAFD has deployed strike teams, dozers, a hand crew, and helicopters, with updates at emergency.venturacounty.gov and lafd.org/alerts; sign up for notifications at notifyla.org.
California officials say two common ambient air contaminants, acrolein and ethylene oxide, may pose cancer risks more than 10 times benzene (about 800 in 1 million), prompting a 45‑day public comment period as OEHHA updates risk values; the finding emerges amid federal rollbacks on ethylene oxide and ongoing concerns about California’s air quality.
Experts warn that candles, diffusers and other scented products release VOCs and nanoparticles that can impair lung function and worsen respiratory issues; to minimize risk, choose fragrance products that are phthalate-free, ensure good ventilation, and consider safer, non-fragrance alternatives to keep your home feeling fresh without polluting the air.
Two wildfires in Broward and Miami-Dade counties continue burning, with the Max Road Fire around 5,000 acres and about 20% contained and the 172nd Avenue Fire around 210 acres and about 30% contained; officials warn air quality and visibility could worsen as crews work to contain the blazes, with no evacuations ordered but road closures and traffic disruptions in the area.
Utah Gov. Spencer Cox says residents’ concerns about the Kevin O’Leary-backed Stratos data center in Box Elder County will be addressed with phased approvals (first cap of 1.5 GW) and state reviews of air quality, water use, and cooling systems, as protesters worry about energy use, noise, and water impacts; O’Leary counters that opposition may come from 'professional protesters' and AI-generated posts, emphasizing sustainability and community rights.
Two southeastern Georgia wildfires — the Highway 82 Fire near Atkinson (at least 87 homes destroyed) and another blaze in Clinch/Echols counties (over 46.9 sq mi burned, at least 35 homes) — continue threatening residents as strong winds loom. More than 150 related fires across Georgia and Florida have created smoky haze and air‑quality warnings; the Highway 82 Fire is about 10% contained over a 14.8‑square‑mile perimeter, while the Clinch/Echols fire is similarly about 10% contained over more than 46.9 square miles. The fires were sparked by a foil balloon hitting power lines and by welding sparks, with drought, gusty winds, and dead trees from past storms amplifying risk. In Florida, Nassau County volunteer firefighter James “Kevin” Crews died after a medical emergency while fighting a brush fire; no Georgia fire deaths or injuries were reported.
New evidence shows that ordinary nightly fan use does not cause irreversible lung damage; any irritation is typically temporary and linked to dryness, dust, or indoor pollutants. Those with asthma, allergic rhinitis, COPD, or dust sensitivities may notice symptoms more, but risks can be reduced by directing airflow away from the face, cleaning blades, using a HEPA purifier, maintaining 40–50% humidity, and ensuring some fresh air exchange. If wheezing or coughing persists, consult a healthcare professional.
During wildfires, smoke and ash threaten health. Stay indoors when air quality is poor and limit outdoor time, especially if you have heart or lung conditions, with a plan for medications. If you must go outside, wear a tight-fitting NIOSH-approved N95 or P100 mask. Improve indoor air with clean furnace/AC filters or a DIY HEPA purifier; if using a generator, place it at least 20 feet from the home and use CO detectors. After the smoke clears, wear protection while cleaning, damp-wipe surfaces, wash ash from toys and pets, and vacuum with a HEPA-filter vacuum.
More than 27,000 acres burned across southern Georgia as drought-fueled wildfires destroy homes and force evacuations in multiple communities; Governor Kemp has declared a state of emergency as smoke degrades air quality from Atlanta to Jacksonville and crews fight the blazes.
ASU researchers warn that heat-accelerated VOCs from asphalt may harm respiratory health, with aging pavement emitting more toxic vapors; algae-infused binders can curb the most toxic emissions by ~100-fold, offering potential health and maintenance benefits. Phoenix-area tests and collaborations aim to scale safer, lower-emission asphalt for future road networks.
Bangor, Maine is the only U.S. city on all three American Lung Association clean-air lists, with zero days of unhealthy ozone and short-term particle pollution and among the lowest year-round particle levels, thanks to its forests, small population, and distance from major polluters. By contrast, Los Angeles has the worst ozone and Bakersfield the worst year-round particle pollution. The findings rely on EPA data from 2022–2024 and come amid concerns about climate change and regulatory rollbacks, while Bangor’s clean air is used as a selling point to attract residents seeking healthier living.
A large explosion at Valero's Port Arthur refinery in Texas sent a thick smoke plume into the air and prompted shelter-in-place orders, which were lifted about 12 hours later as officials said there were no fatalities or injuries. The Texas Commission on Environmental Quality deployed air-monitoring teams and Valero coordinated with local authorities; the refinery employs about 770 people and processes roughly 435,000 barrels per day. The incident comes amid volatility in oil and gas prices linked to global supply concerns tied to the Iran war.
A Danish study finds that burning candles releases vast numbers of ultrafine particles (about 7–8 nanometers) and gases like nitrogen dioxide and PAHs, in some cases more than cooking, and these tiny particles can penetrate deep into the lungs and potentially the bloodstream. Even mild asthma showed measurable inflammation after exposure. To reduce risk, use LED candles, burn fewer candles, place them away from drafts, trim wicks, and ventilate the room after use; indoor air quality matters for everyone, especially those with respiratory conditions.
A December 2025 study in Environmental Science & Technology finds that aerosols from e-cigarettes can become chemically reactive after lingering in indoor air, forming organic hydroperoxides and radicals; ultrafine particles concentrate redox-active metals like arsenic, tin, and lead, creating a “chemical cocktail” that may raise respiratory health risks for bystanders. The researchers urge treating vaping emissions like secondhand smoke and reducing indoor exposure, aligning with global policy debates and bans on vaping.
