Air quality is a major public health issue and a real concern for stakeholders. Volatile Organic Compounds (VOCs) are among the major air pollutants. VOCs are defined as any compound of natural or anthropogenic origin that contains carbon and hydrogen (excluding methane). VOCs also include more complex substances where some hydrogen atoms may be substituted by oxygen, nitrogen, sulfur, or halogen atoms (especially chlorine or fluorine). These compounds are in the state of gas or vapor under normal conditions of temperature and pressure.
