Organic Pollutant Contamination of the river Elbe as Assesed by Biochemical Markers
Original language description
The aim of the study was to assess contamination of the River Elbe basin using selected biochemical markers. Biochemical markers selected were enzymes of the first stage of xenobiotic transformation, namely cytochrome P450 (CYP 450) and ethoxyresorufin-O-deethylase (EROD). The results were correlated with the most important inducers of the enzymes, i.e. polychlorinated biphenyls (PCB) concentrations in muscle tissue of fish, polyaromatic hydrocarbons (PAH) values in bottom sediments and 1-hydroxypyrene(1-OHPY) values in fish bile (terminal metabolite of PAH, or, rather, of one of them, i.e. pyrene), which were determined during the chemical monitoring of the River Elbe basin. The indicator species selected was chub (Leuciscus cephalus L.), which was captured at ten locations in the River Elbe basin. A comparison between the EROD activity and the CYP 450 content along the longitudinal profile of the Elbe showed a significant orrelation at the level of significance of p < 0.05. The high
