Abstract:In this paper, selenium (Se) and arsenic (As) contents of soil and plants were determined by Hydride Generation Atomic Fluorescence Spectrometry (HG-AFS) and sulfur (S) contents were examined by Coulomb titration, and the relationships of Se, As and S in soil and plants were discussed. It shows that both Se and As have the same change trend. Se has positive correlation with S, if the S content of soil is less than 0.05%, but the correlation is negative, if the S content of soil is more than 0.05%. Se in soil has stronger influence than As and S on the corresponding elements in plants. Distribution of Se, As and S in plant indicates that radish and rice with high Se content have stronger ability than potato and batata with low Se content to gather As and S.
