“…Similar studies using sea urchin sperm of Paracentrotus lividus have also revealed genotoxic properties of ZnO and CuO NPs [ 27 , 43 ]. In addition, the genome sensitivity of male gametes to various nanoparticles has been shown in other marine invertebrates, including the bivalve Tegillarca granosa [ 44 ], the polychaete Hydroides elegans [ 45 ] and the ascidia Ciona intestinalis [ 46 ].…”

Products containing nanomaterials are becoming more and more common in everyday life. Zinc oxide nanoparticles (ZnO NPs), meanwhile, are among the most widely used NPs. However, their genotoxic effect on the germ products of marine organisms is poorly understood. Therefore, the effects of ZnO NPs and zinc ions (20, 50, 100, 200 µg/L) on the sperm of sand dollar Scaphechinus mirabilis were compared. Comet assay showed that both tested pollutants caused an increase in DNA damage to 6.57 ± 2.41 and 7.42 ± 0.88% DNA in the comet tail, for zinc ions and ZnO NPs, respectively. Additionally, a different pattern was shown by the increase in DNA damage, with increasing concentration of pollutants, in different experimental groups.
