Nanoscale Iron Could Help Cleanse The Environment; Ultrafine Particles Flow Underground And Destroy Toxic Compounds In Place Date: September 4, 2003 Source: National Science Foundation Summary: An ...

To achieve high efficiency in cleaning the gas flow from pollutants, more and more advanced technologies are required. The main problem of purification from particulate matter is the insufficient ...

Dosimetry parameters such as deposition, clearance, retention, and translocation and dissolution of inhaled particles in and to different lung compartments may be important for the persistence of ...

These emissions are huge contributors to air pollution and contribute to the risk of disease for those living near major roads. There is a constant flow of exposure to a complex mixture of all sorts ...

Ultrafine particles are aerosols less than 0.1 micrometers, or 100 nanometers, in diameter—about one-thousandth the width of a human hair.

Ultrafine particles are a subset with a diameter of less than 0.1 micrometres. “That makes them very dangerous, because, being so small, they can get very, very deep into the human body,” says ...

Ultra-fine Particles, Particularly Harmful To Health, Can Now Be Traced Date: October 6, 2009 Source: Fraunhofer-Gesellschaft Summary: Limit values for fine dust emissions are based on total ...
