This trend indicates that the plants collected from natural areas, such as _Achillea millefolium_ and _Taraxacum officinal_, present the highest concentrations of \(\Sigma\)16 PAHs (1626.51 \(\pm\) 65.92 and 2466.46 \(\pm\) 203.45 \(\upmu\)g/kg, respectively), while _Matricaria chamomilla_, which grows both in the wild as well as in cultures, has the lowest concentration of 277.22 \(\pm\) 12.78 \(\upmu\)g/kg. The obtained data show that the studied plants accumulated high levels of PAHs. Several studies showed that a series of factors, such as the plant species, age, environmental characteristics in which they grew and aerial deposition, can determine the presence of compounds in plants [21; 22; 23].
