Abstract With the rapid development of the transgenic food，more and more transgenic food has been pouring into the market,raising concerns about transgenic food’s edible safety. Transgenic corns and their parents were scanned by ICP-MS to detect the contents of Li,Se,Mo and Cr. The results showed that the contents of Li,Se,Mo and Cr were much lower than those of their parents,especially the contents of Se and Mo in Bt corns were several times lower than their parents. All the results showed that the nutrients for human health could decrease due to the insertion of foreign genes,so transgenic should be strictly supervised before commercialization. And the molecular mechanism of the decrease in microelements should be further studied.
