With two whole infertile eggs and two incomplete infertile eggs (having shell me mbrane and shell) of Chinese Alligator (Alligator sinensis) from the artific ial condition and the field in Anhui Province，the authors studied the concentra tion of four heavy metal elements (Cu，Zn，Cd and Pb) in the different parts (al bumen，yolk，shell membrane and shell) with Atomic Absorption Spectroscopy (AAS) .Our results showed that these four elements' concentration was quite different in the different parts of the same egg.The concentration of these four elements from high to low is Zn，Cu，Pb，Cd in the albumen，yolk and shell membrane of th e infertile egg.However the sequence is Zn，Pb，Cu，Cd in the shell of the infer tile egg.The concentration of Zn (the highest is 63.29 mg/kg) is higher than t he other three elements in the same egg.The concentration of Cu (the highest is 20.03 mg/kg) is higher in the shell membrane than the others parts of the same egg.The concentration of Pb (the highest is 26.8 mg/kg) is hi
