Wykorzystanie testu mikroja̧drowego do oceny genotoksyczności odcieków ze składowiskodpadów

The cytogenetic biotest was used to examine the genotoxicity of landfill leachates by analyzing the changes in thefrequency of micronuclei formation in the cells of Viciafciba root-tips. The leachate samples collected for the purpose ofthe study came from two landfills differing in age, both situated in the Upper Silesian Industrial District (Gliwice,Zabrze). The results of the study have disclosed a significant relationship between the frequency of micronuclei formation,chromosome aberration and concentrations of the leachates, expressed in terms of organic carbon content. The micronucleusbioassay was found to be a valuable tool for monitoring the genotoxicity of environmental samples. The results obtained canbe of significance in the light of the European Commission debates on updating the list of priority substances that are to beidentified and monitored in the aquatic environment under the regulations of Directive 200/60/EU.
