Outline of Final Research Achievements

We prepared different samples of Hg(II) ion-contaminated soils and cultivated rice therein, to confirm the differences in MeHg production in soils and its effect on MeHg accumulation in rice grain. Pot experiments were performed in two different soil types, soil I and soil II, to each of which 10 mg/kg Hg(II) ion was added. Rice was planted on 2015, 2016, and 2017 at same soil.
The maximum MeHg concentrations of soil I and II were obtained in 2015. However, MeHg concentrations of soils were decreased in 2016 and 2017 in comparison with 2015 . We believe that the reason is the change of added Hg(II) ion form to other inorganic Hg forms. MeHg concentrations in brown rice at each pots were decidedly affected by the MeHg concentration in soils. MeHg and T-Hg concentrations were measured in all three parts of the brown rice grain (embryo, bran, and endosperm) and found to be 3.18 and 3.86 mg/kg, 0.74 and 0.90 mg/kg, and 0.49 and 0.53 mg/kg, respectively.
