A concentration of seven indicator polychlorinated biphenyl (PCB) congeners (IUPAC No. 28, 52, 101, 118, 138, 153, and 180) in root vegetables was investigated. Plants were grown on equally spiked soils with different physico-chemical properties. The concentration of PCB in all screened plants was higher in roots than in shoots, with a 1.5-3.9-fold higher content in vegetables grown on the Fluvisol compared to the Chernozem. Parsley was more efficient in extracting PCB from soils, followed by carrot and red beet. The majority of PCB accumulated in peels and ranged between 75.3% (red beet) to 93.6% (carrot), regardless of soil type. Lower chlorinated biphenyls were more abundant in surface root layers (peel, cortex). The core of all screened plants showed an almost even distribution of congeners with a higher abundance of hexachlorinated biphenyls.
