Air pollutants are those substances that are known or suspected to cause serious environmental and health hazards. A wide range of primary air contaminants can be released directly from both natural and anthropogenic sources. Besides, secondary air pollutants can be formed in the atmosphere via oxidation or photochemical reactions of primary air pollutants. Air pollution monitoring pursues the ambitious objective of improving the overall quality of the environment (Gurjar et al., 2010). In this regard, the US EPA has reported a comprehensive list of 187 hazardous air pollutants (HAPs), which includes compounds from very volatile to nonvolatile organic and inorganic.
