The extent to which biological systems interact in fish from multi-contaminant areas needs to be understood for full interpretation of monitoring data. This study investigates the interaction between two biomarkers, ethoxyresorufin-O-deethylase (EROD) activity and plasma vitellogenin (VTG) in the European

Polycyclic aromatic hydrocarbons (PAHs)--environmental carcinogens--are metabolized by CYP1A1 and CYP1A2 enzymes to oxy-derivatives, which are able to bind to DNA and initiate carcinogenesis. PAHs induce CYP1A1 and CYP1A2 activity, which increases the risk of development of carcinogenesis. Isothiocyanates (ITCs), naturally
