DNA damage as a consequence of toxicant exposure may in the long run influence health and survival of the organisms. Therefore, it is of paramount importance to develop and test sensitive molecular cytogenetic methods for early detection and assessment of these changes. The aim of this study was to assess DNA damage in zebrafish (Danio rerio) exposed to model genotoxicants (Benzo[a]pyrene (B[a]P), Ethyl methanesulfonate (EMS)) and to determine the longevity of such damage. The primary DNA damage was detected using Comet assay whereas the long-term effects were monitored using the AFLP (amplified fragment length polymorphism) method. The results of this study demonstrated the primary DNA damage caused by model genotoxicants as well as persistence of alterations in the zebrafish genome even one year after the end of the genotoxic exposure. Zebrafish was confirmed as suitable model organism in studies of genotoxicity.
