| Outline of Final Research Achievements |
The Small Indian mongoose is listed as one of the world's 100 worst alien species, and in the areas where it is introduced, it is subject to extermination in order to prevent destruction of the native ecosystem. The purpose of which was to elucidate the characteristics of dam-to-fetus transfer due to exposure to trace elements in the natural environment.
As a result of analyzing 29 pairs of dams with high mercury levels and their fetuses, a strong positive correlation was observed between the concentration of organic mercury in maternal whole blood and fetal blood, as in humans.Mongoose fetuses were suggested to transfer less mercury from their mothers than humans. From the analysis, it was inferred that the mineralization of organic mercury and the arsenic concentration in the fetal liver were involved as factors for low mercury transfer to fetus brain.
