Objective: To study the contents, distribution and correlation of Cu, Fe, Cr, B in normal fetal organs.
Methods: The samples were digested by closed-vessel microwave HNO3 + H2O2 dissolution system. The solution was directly analyzed by ICP-AES for determination of Cu, Fe, Cr, B in fetal cerebra, cerebellum, heart, liver, kidney, gastrocnemius, placenta and mother serum.
Results: The four elements mainly existed in fetal liver. There were correlations between four elements in the same organ as well as between the same element in different organs.
Conclusion: There existed some correlations in the contents and distribution of Cu, Fe, Cr, B in normal fetal organs.
