- selenium-rich soil crops distribution of Se enrichment of heavy metals effects of Se
36 kinds of crops and the planting soils had been treated as research samples. All the materials came from Nandu river basin selenium-rich region. 120 research samples had been chosen to research the distribution of selenium and their effects on enrichment of heavy metals in selenium-rich regions. The results showed that the amount of selenium (based on fresh weight) are of the following order: grain and oil species>leaf vegetable species>potato species >bean species > melon and fruit species. The parameter order (BCF) of selenium enrichment (from high to low) was leaf vegetable species potato species> grain and oil species > melon and fruit species bean species; Based on the standard of the amount of selenium that the selenium-rich food has, leaf vegetable species should be the optimal crops for developing among all these species; Pb and Cd show associated effect with Se in selenium-rich soil, the associated effect between Se and Cd was significant. Selenium-rich soil shows no significant effects on the enrichment of heavy metals in crops, it showed antagonism effect to Pb and synergistic effect to Cd.
