- Abstract
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.
