“…Significant advantages of new microextraction techniques in sample preparation include automation, reduced extraction time, high efficiency, reduced solvent volume and short extraction time (Hill, 2003; Ouyang & Jiang, 2016; Pawliszyn, 2002). Owing to the great benefits of microextraction methods, there is a growing interest in the application of these methods in various fields, such as toxicology, biochemistry, food, medicine, cosmetics and the environment (de la Calle et al, 2016; Ocaña‐González et al, 2016; Rezazadeh et al, 2014). Microextraction techniques can be simultaneously applied for sampling and extracting BTEX compounds by sampling them in the air and applying the results to prepare the metabolites of these compounds in biological samples (Figure 1).…”
