A combination of sewage overflows and coastal winds could be sending billions of airborne microplastic particles into the ...

How tiny plastic particles enter the atmosphere is an important question, as airborne microplastics are a potential health threat. Using a global chemical transport model, researchers have provided ...

An N95, for example, is named as such because it is at least 95% efficient at blocking airborne particles when used properly. But even if a mask has an 80% efficiency, Marr said, it still offers ...

During the experiment, airborne particles ejected from the toilet traveled at speeds of up to 6.6 feet per second and reached 4.9 feet above the toilet within eight seconds, the scientists found.

The World Health Organization is opening up the definition of airborne pathogens – such as Covid-19, influenza and measles – to include when respiratory droplets spread through the air and ...

Compared to more powerful or full-featured Dyson air purifiers, the Dyson TP10 might seem basic, but it’s well-equipped with a HEPA filter that captures particles as small as 0.3 microns while ...

At both 40% and 60% relative humidity, half of the airborne coronavirus particles were still infectious after aging for one hour in the chamber. But at 25% humidity, that time doubled: Half of the ...

Energetic airborne particles from the plume made unpredictable movements, but mostly traveled upwards, rising to the lab’s ceiling, backward towards the rear wall, and outward, spreading forward ...

For example, air purifiers equipped with HEPA filters were found to be more effective than HVAC systems (Heating, Ventilation and Air Conditioning units) at filtrating airborne particles as small ...

"These filters can remove up to 99.97% of small airborne particles, including dust, pollen, and mold spores," Dr. John McKeon, the CEO of Allergy Standards and a principal at the Indoor Air ...

Airborne diseases can pass from one person to another when particles that contain pathogens enter into the air, and some then remain suspended there. A range of fungi, viruses, and bacteria can ...
