In this study, polycyclic aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) contaminations in the leaf, stem and root tissues of common mallow (Malva sylvestris L.) were investigated by using gas chromatography to give an insight into the bioaccumulation of these persistent pollutants. The sampling stations are located in the Dilovası and İzmit Districts of Kocaeli Province in Turkey. Total PAH concentrations varied between 10.44 and 61.15 pg g-1 dw (dry weight). The most dominant PAH congeners were Acenaphthene and Acenaphthylene which are low molecular weight. Total PCB concentrations were found to be between 326.79 and 4496.42 pg g-1 dw. PCB 66, PCB 110, PCB 153 and PCB 180 were found to be the most dominant congeners. Detected concentrations in root tissues showed the plant’s ability in accumulating these pollutants. Therefore, these findings suggest that Malva sylvestris can reflect the contamination levels which might be used to monitor soil and ecological pollution levels caused by these persistent pollutants.
