Abstract With the rapid development of transgenic cotton, people begin to focus on its physiology and ecology. The present paper studied the contents of heavy metals and microelements in transgenic cotton seeds by ICP-MS/ICP-AES. The results showed that the content of most microelements detected in transgenic cotton seeds, B, Na, Si, P, K, Ca, Mn, Co, Ni, Zn, Se and Mo was lower than that in regular cotton seeds, except Mg, Fe and Cu. And the content of most heavy metals detected in transgenic cotton seeds, Al, As, Cd, Sb, Tl, Pb and Bi, was higher than that in regular cotton seeds, except Cr and Hg. All the data showed that the accumulation of heavy metals and microelements in transgenic cotton seeds is disadvantageous to itself.
