Due to the several types of VOCs and the diversity in their physico-chemical properties, it is difficult to develop standard methods for sampling and analysis. The majority of methods depend on the compounds of interest and the required duration of sampling. Each method is associated with a certain value of specificity and sensitivity. To date, however, no specific method qualifies as being the most accurate. This review reports the most common methods employed in determination of VOCs, based on the international literature. 1. INTRODUCTION Volatile Organic Compounds (VOCs) are highly reactive aromatic hydrocarbons. Example compounds are benzene, toluene, ethylbenzene, m-xylene, o-xylene, p-
