Determination of Benzene in Ambient Air

Apart from its synergistic effect with pollutants and its ability to damage different components of the biosphere, benzene is a proven carcinogen. Studies have shown that organic compounds such as benzene, toluene, ethylbenzene and xylene, called BTEX among VOCs, are higher in ambient air.

Benzene, which is classified as "Category A", that is, "known human carcinogen", within the scope of EPA risk assessment guidelines, requires special attention. Exposure to benzene through oral or inhalation causes toxic effects. Considering its toxic effects, there is a need to monitor and regulate benzene in the ambient air.

Benzene can remain in the air in the vapor phase for several hours to several days, depending on environmental conditions and the presence of airborne pollutants. There are both natural and anthropogenic sources of benzene. It can arise naturally from volcanoes and forest fires, or anthropogenically from crude oil, gasoline and industrial processes. It is used in the production of plastic, resin, synthetic fiber, rubber, paint, detergent, medicine and pesticides. Additionally, the most common source of benzene indoors is cigarette smoke.
