AIR MONITORING

摘要

Atmospheric Particulate Matter (PM) or aerosols play a key role in the atmosphere as particles cause visibility reduction, act as clouds condensation nuclei, affect the global climate change and are responsible for adverse health effects. Carbonaceous Aerosol (CA), typically emitted by incomplete combustion of fossil fuels related to traffic, industrial processes and domestic heating, is one of the main components of PM especially in urban environments and it is very important from the climate change point of view too, since Elemental Carbon (EC), which, depending on the technique adopted to reveal it, can also be called Black Carbon (BC), is the primary responsible of light absorption and of the direct radiative effect of aerosol on climate.
