how it can travel long distances and persist in the air, changing over time and getting more toxic. Wildfire smoke contains noxious or poisonous gases and particulate matter, tiny particles that ...

Increasing ventilation with outside air has been proven to reduce transmission of airborne diseases by lowering the concentration of infectious particles in the air. In a 2019 study of an ...

A pioneering method to simulate how nanoparticles move through the air could boost efforts to combat air pollution, suggests ...

The eruption threw thousands of tonnes of mineral ash into the air - forced higher by steam plumes created as glacial ice melted. Most of it was very fine particles which formed an ash cloud, rising 6 ...

Airborne microplastics and nanoplastics are increasingly detected in urban environments, with evidence linking inhalation ...

ventilation and circulation → Sarah Kobos An air purifier’s HEPA filtration can clear most particles by exchanging air quickly. Use one purifier per room, continuously on a low speed.

Research has found tiny air particles in pollution don't just harm our lungs. They can also damage our digestive systems, including livers and intestines. Fine air particles, known as PM2.5 ...

We quantified the long-term health impacts of exposure to these pollutants by combining mortality data from vital records in New York State and using a model that tracks how particles move and change ...

The best air purifiers for smoke are effective at filtering out microscopic particles that can lead to coughing, stinging eyes and a scratchy throat, among other symptoms. Our top recommendation ...

Many of the best air purifiers boast filters that can trap at least 99.97% of particles measuring as little as 0.3 microns. This means that, in theory at least, they can get rid of smoke ...

Air pollution particles inhaled by pregnant mothers can make their way into the tissues and organs of developing fetuses, according to a new study. Although the health consequences are not yet ...
