| 摘 要： | 扬子鳄Ａｌｌｉｇａｔｏｒｓｉｎｅｎｓｉｓ属于爬行纲鳄目鼍科 ,它是我国特有的珍稀物种。近几十年 ,由于其栖息地片段化、岛屿化 ,加之农药污染等人类生产活动的影响 ,使得野生扬子鳄种群数量明显下降 (Ｔｈｏｒｂ ｊａｒｎａｒｓｏｎ＆Ｗａｎｇ ,1999)。王小明等 (1999)的调查结果表明 ,野生扬子鳄数目不足 2 0 0条 ,处境十分危险。深入研究野生扬子鳄种群的致危因素及其机制 ,是避免野生扬子鳄遭受灭绝的关键。有关扬子鳄的繁殖 (顾文仪和张海生 ,1983;陈壁辉和王朝林 ,1984;汪国宏等 ,2 0 0 0 )、栖息地类型 (渡部摩娜等 ,1982 ;黄祝坚… |

| Abstract: | With two whole infertile eggs and two incomplete infertile eggs (having shell membrane and shell) of Chinese Alligator ( Alligator sinensis ) from the artificial condition and the field in Anhui Province,the authors studied the concentration of four heavy metal elements (Cu,Zn,Cd and Pb) in the different parts (albumen,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 the infertile egg.However the sequence is Zn,Pb,Cu,Cd in the shell of the infertile egg.The concentration of Zn (the highest is 63 29?mg/kg) is higher than the 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 higher in the shell than the other parts of the same egg.The concentration of Cd (the minimum is 0 024?mg/kg) is much lower than the other three elements in the albumen,yolk and shell membrane of the same egg.In addition,our results also showed that the concentration of these four elements tended higher in the infertile egg from the artificial condition than that from the field.The results should be considered by Chinese Alligator Breeding Center. |
