Abstract：With the rapid development of transgenic plant,the protection of species is becoming more and more important. The contents of wholesome elements and heavy metals in ten soybean species from northeastern China were studied by ICP-MS/CIP-AES to detect the heavy metals and microelements. The results showed that the Northeastern soybean contained many elements necessary to human health,the sequence of macroelements (higher than μg·g-1) was K>P>Mg>Ca>Fe>Rb>Mn≈Zn>Si≈Na≈Al≈Ba≈Ni≈Cu,and the most important is that the contents of Fe,Mn and Zn range from 20 to 80 μg·g-1,which are important to human health. Besides the microelements,the contents of heavy metals (As,Cr,Pb and Cd) are also the important standard to identify the quality of farm produce,and the results showed that northeastern soybean contained little heavy metals except Cr (near 200 ng·g-1). All the data showed that northeastern soybean accords with the national hygiene standards,but the protection should be strengthened.
