Results from the Sea Urchin Egg Fertilization and Embryotoxicity Tests The outcomes with the sea urchin egg fertilization test revealed no contraceptive activity soon after the influence from the samples obtained from gasoline-powered vehicles (HusTE, HonVT, TMar2, and MiPaj). However, the samples obtained from diesel-powered vehicles (THi, TLC80, and KomPC) nearly absolutely prevented egg fertilization and madeToxics 2021, 9,10 of3.4. Final results of the Sea Urchin Egg Fertilization and Embryotoxicity Tests The results from the sea urchin egg fertilization test revealed no contraceptive activity after the influence from the samples obtained from gasoline-powered vehicles (HusTE, HonVT, TMar2, and MiPaj). Even so, the samples obtained from diesel-powered vehicles (THi, TLC80, and KomPC) practically fully prevented egg fertilization and made the eggs sterile. No fertilization was registered even after the addition of a new portion from the spermatozoa (100 , 1 108 cells/mL). Furthermore, the optical microscopy demonstrated adsorption on the THi, TLC80, and KomPC samples to the surface from the embryos (Figure S6). The concentrations that triggered 50 of embryo mortality (LC50) have been calculated for all of the VEPs samples (Table five). The PHA-543613 Epigenetic Reader Domain highest toxicity was registered for the THi sample. Having said that, generally, each of the tested samples had a comparable degree of toxicity. The alterations in embryo development right after exposure to the VEPs are shown in Figure 6. All the VEP samples brought on a comparable Nitrocefin supplier amount of developmental disorder within the sea urchin embryos.Table five.
