Polychlorinated dibenzofuran (PCDF) isomers, which are usually produced thermal processes, have been classified as the mutagens and carcinogens (Coutinho et al. 2015; Squadrone et al. 2015). Incinerators and boilers have been considered as the major causes of PCDFs production after waste burnings (Wittsiepe et al. 2015; Pongpiachan et al. 2016). Production of PCDFs cause the ecosystem and environmental media contamination (Klees et al. 2015; Kruse et al. 2014; Shin et al. 2016). PCDFs have strong environmental persistent characteristics and they are also subjected to biomagnification as well as bioaccumulation effects in many living organisms (Hanano et al. 2014; Wu et al. 2014; Yang et al. 2015). Different furan isomers including octachlorinated dibenzofuran (OCDF, a highly chlorinated furan), have been observed in different environmental media (e.g., sediments, soils) in many industrialized areas (Govindan and Moon 2015; Urban et al. 2014).

Some of the toxic effects of PCBs such as hepatic injury appear to result from electrophilic intermediates produced during metabolism (Shimado and Sato, 1978). PCB mixtures also contain several other chlorinated compounds, such as polychlorinated naphthalenes and polychlorinated dibenzofurans (PCDFs) (Sittig, 1985). The presence of these PCDFs in PCB mixtures may arise from the distillation process during purification (George et al., 1987).

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) belong to the chemical family of chlorinated polycyclic aromatic hydrocarbons, which contain one to eight chlorine atoms and are generically referred to as dioxins and furans, respectively (Chang 2008; Guemiza et al. 2017). The 75 different PCDD congeners and 135 PCDF congeners are distinguished by their number of chlorine atoms and these atoms’ positions. Only seven of PCDD congeners and ten of the PCDF congeners, those with chlorine substitution in positions 2, 3, 7, and 8, have dioxin-like toxicity. These 17 congeners are commonly analyzed in environmental samples (Kulkarni, Crespo, and Afonso 2008).
