Název v původním jazyce
Fractionation of parasite communities in relation to heavy metals and persistent organic pollutants
Popis výsledku v původním jazyce
Parasitism and level of contamination of gudgeon were studied at localities with different chemical pollution (Bílina, Vlára and Ponávka Rivers, Czech Republic). The relationship among developmental instability (measured as deviation from perfect bilateral symmetry of 10 meristic and 8 morphometric fish traits), parasitism, concentration of selected pollutants in muscle and hepatopancreas of fish (mercury, nickel, PCBs, p,p-DDE etc.) and hepatopancreatic 7-ethoxyresorufin O-deethylase (EROD) activity, abiomarker of exposure of fish to dioxins and dioxin-like toxicants, were analysed. Detected level of PCB, p,p-DDE and some heavy metals (e.g. Ni, Zn, Hg) and EROD activity in muscle and hepatopancreas of gudgeon differed among fish from different localities. However, there was no significant difference in the developmental instability of fish among studied sampling sites. With the exception of one fish, all examined gudgeon were infected with metazoan parasites.
