Although an accurate evaluation of the distribution of ultrafine particulate matter in air is of utmost significance to public health, the usually used PM 2.5 index fails to provide size ...

To address this issue, a multi-institutional team of researchers used a tethered balloon system to collect atmospheric particles in a vertical profile up to 750 meters above ground level.

In testing, the device proves capable of detecting point sources of atmospheric particulates like flowers and a toaster. It’s something we’re sure would prove handy to those working in HVAC ...

The mix of materials from homes, vehicles and buildings is enough to cause concerns about short- and long-term biological harm, she said. Wildfire smoke produces particles in the air that can ...
