Sažetak
Permanent and quality monitoring of pollution is a subject of current research at the part of Croatia. During the last eight years, a whole range of experiments were carried out with the purpose of finding the optimal biomonitoring method and establishing permanent biomonitoring on these two rivers. The autochthonous fish and molluscs species biological characteristics, as well as the hydrogeological and climatic properties of habitat together with some sociological phenomena, determine the specific approach of designing a biomonitoring in this area. As the results showed great variability and obvious dependence of many common parameters on environmental factors, besides biomarkers of effect and biomarkers of exposure and effect (EROD, ECOD, AChE, MT) other parameters were measured of exposure and effect (EROD, ECOD, AChE, MT) other parameters were measured as well. These other parameters can be classified as a biomarkers of xenobiotic burden: glutathione peroxidase (GPx), catalase (CAT), gluthatione-S-transferase (GST), total gluthatione (GSH), oxidized/reduced glutathione ratio and a biomarkers of metabolic activity and health condition: citrate synthase (CS), alanin-transaminase (ALT), asparthate-transaminase (AST), lactate-dehydrogenase (LDH) and glucose concentration (gluc). Those parameters were measured in muscles, blood/hemolymph and fish brain. A comparative overview of used species is given in this presentation according to/concerning their ecological characteristics and measured parameters in specimens from polluted and unpolluted sites on the river Drava and the river Danube. Used species were: common carp (Cyprinus carpio), prussian carp (Carrasius gibelio), poison fish (Ictaulurus nebulosus), bream (Abramis brama), swan mussel (Anodonta cygnea), painter mussel (Unio pictorum) and zebra mussel (Dreissena polymorpha). The results showed that the interpretation of results of monitoring using molecular biomarkers on a river is much more complex and difficult when compered with marine biomonitoring results interpretation and it necessarily have to include considerable quantity of ecological, as well as biochemical, parameters.
