| Summary: | Gaseous pollutants such as SO2 and NOx once emitted to the atmosphere is oxidized to sulphate and nitrate through gaseous and aqueous phase processes. The absorption and desorption of gaseous pollutants by water droplets is the beginning of the removal process of these gases. However, absorption and desorption involve a complex mechanism which incorporates dissolving and extraction of these species in and out of water droplets.This paper will discuss the possible mechanism of absorption as an example of the behaviour of the atmospheric pollutants. Altough, Saudi Arabia has a dry atmosphere in general, the proposed phenomenon is an important one in the coastal cities specially in the summer. |
