Atmospheric sulfate particles reduced, but as acidic as ever Date: February 22, 2016 Source: Georgia Institute of Technology Summary: Tough emission controls have dramatically reduced the amount ...

From the intra-zone analysis of the data, the time-averaged exposure to fine and coarse particles, for medium floor loadings on CP carpeting ranged from 6.3 to 14.3 (fine PM) μg/m 3 and 1.1 to 19 ...

Atmospheric sulfate particles reduced, ... scientists had expected the pH of the sulfate fine particles to rise toward neutral levels. But the pH remains between 0 and 2 ...

Earth's atmosphere, it turns out, is dustier than scientists previously thought. Dust in the upper atmosphere interacts with clouds, oceans and even radiation, or heat, from the sun. It can affect ...

Coarse particles refer to particulate matters between 2.5 and 10 micrometers in diameter. Particles measuring 2.5 micrometers or less in diameter are called fine particles.

Dust particles thrown up from deserts such as the Sahara and Gobi are playing a previously unknown role in air pollution, a new study has found. The international study published in National ...
