The study conducted by Hiller et al. (2011) to investigate the concentrations, distributions,
and hazards of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons
(PAHs). PCBs are used mainly as coolant and electronic industries (capacitors,
transformers), paints, sealants for wood, cutting and lubricating fluids, plasticizers, and as
dielectric fluids. Therefore, at the former site of PCB manufacturing area in Slovakia, high
concentrations of PCBs are detected in soils, sediments, humans, and wildlife (Kocan et al.,
2001; Petrik et al., 2001; Hiller et al., 2011)....
