Oak trees Southern cities U.S. natural urban air filters
2019/10/18
Researchers at the University of North Texas have found that two oak tree species, post oak and live oak, that are widespread across the U.S. South remove black carbon from the urban atmosphere. The f...
The air we breathe contains particulate matter from a range of natural and human-related sources. Particulate matter is responsible for thousands of premature deaths in the United States each year, bu...

Radon Decay Product Aerosols in Ambient Air
Radon Decay products 214Pb 212Pb 210Pb Radioactive aerosols Cascade impactors 1-ACFM AMAD Residence time
2016/3/29
The aerodynamic size distributions of radon decay product aerosols, i.e. 214Pb, 212Pb, and 210Pb were measured using low-pressure
(LPI) as well as conventional low-volume 1-ACFM and high-volume (HVI)...
Air Ion Variation at Poultry-farm, Coastal, Mountain, Rural and Urban Sites in India
Pollution index Aerosol Air ion Transpiration Meteorological Parameters
2016/3/25
The air ions are continuously generated and destroyed by various processes in the atmosphere. Near the surface, the nature
of ions is very complex and they show large variations in their physical pro...
Protecting the environment during economic growth is a challenge facing

Air pollution Air quality
2015/9/21
To prepare for the 2008 Olympic Games, China adopted a number of radical measures
to improve air quality. Using the officially reported air pollution index (API) from 2000 to

An important reason for controlling air pollutants such as particulate matter or sulfur dioxide
is the damaging effects they have on human
health. These effects include premature death
as well as i...
