“…The extent of DNA damage taken place along with an increasing number of gill cell damages of transplanted blue mussels described that transplanting method could be used for assessing the impact of such geno-toxicants like tributyltin to marine animals. It was also explained that transplanting mussels facilitated measuring biomarkers like DNA damage and made this tool more flexible when used for manipulative field testing and hypothesis testing (Bolognesi et al, 2019;Gecheva et al, 2020;Perovic et al, 2020;Dos Figure 5. Distribution of DNA damage based on percentage DNA in the comet tail of blue mussels gill cells in different treatments.…”

Pollutants in waters that cause DNA damage, such as tributyltin, have been known to cause malformations in the mussel shell, which need attention to be studied. Shell malformations or deformities of blue mussels were observed in Norsminde Fjord harbour. The mean shell thickness index of blue mussels from the polluted site was greater than it from expected clean waters. DNA damages detected using the versatile comet assay which expressed as tail length and olive tail moment were evaluated in blue mussels gill cells both in situ and in vitro. The results showed that the average of DNA damages in treatments, namely the polluted site, tributyltin chloride (TBTC) (10 g/l), and hydrogen peroxide (H2O2) (10 M) were different from the expected unpolluted site. Although comet assay is considered as an unspecific assay, the results proposed the similarity of DNA damage character of blue mussel gill cells when exposed to tributyltin chloride and taken directly from the polluted site. The data obtained are important for assessing the environmental risks created by genotoxic agents, e.g. tributyltin, used as antifouling agents in marine paints.
