| Summary: | No abstracts are to be cited without prior reference to the author.In the Baltic Sea, there are exclusive zones—the Bornholm zone, the Gotland Deep and the Little Belt Sea—where many thousand tonnes of chemical munitions (CM) were dumped after the Second World War. The goal of the study is to assess environmental genotoxicity levels in different fish species inhabiting dumped CM sites with the aim of outlining genetic risk levels, integrating stress and fish population health. Genotoxicity biomarker responses, such as the formation of micronuclei (cytogenetic and DNA damage), nuclear buds (DNA damage), binucleated cells with nucleoplasmic bridges (radionuclide effects), binucleated, 8‐shaped cells (alterations in chromosome segregation and cytokinesis), or fragmented apoptotic cells (elimination of cytogenetic damage), were analysed in blood erythrocytes of flounder, dab, plaice, turbot, herring, and Atlantic cod. Multifactorial analysis of genotoxicity biomarker responses was applied in relation to fish ... |
