本文用原子吸收分光光度法测定了1977 ~ 1980年捕获的59头条纹海豚肌肉、肝脏和肾脏中Fe、Mn、Zn、Cu、Pb、Ni、Cd和Hg的含量。除肾脏Cd含量最高外，其余各金属含量肝脏均高于其它组织。金属浓度的频率分布大多数是对数正态分布。在所有器官中，Fe、Pb、Ni、Cd和Hg的含量与体长、体重和年龄呈正相关，Mn、Zn和Cu的含量与体长、体重和年龄呈负相关。Fe、？？、Zn和Cu对体长和体重的影响大于对年龄的影响，说明代谢周转比年龄和暴露时间更重要。而Pb、Ni、Cd和Hg的浓度与年龄密切相关，表明年龄或暴露时间是影响这些金属积累的主要因素。
The concentrations of Fe, mn, Zn, Cu, Pb, Ni, Cd and Hg in the muscle, liver and kidney of fifty nine striped dolphins captured during 1977 ~ 1980 were determined by atomic absorption spectrophotometry. The levels of most the metals examined were higher in the liver than the other tissues, except for the highest renal Cd. The frequency distribution of the metal concentrations was mostly log-normal. For all of the organs, correlation of the metal concentrations to the body length, weight and age was positive for Fe, Pb, Ni, Cd and Hg, and negative for Mn, Zn and Cu. A higher correlation of the concentrations of Fe, ??, Zn and Cu to the body length and weight than to the age indicates that the metabolic turnover is more important than age or exposure time in determining the levels of those metals. Whilst the concentration of Pb, Ni, Cd and Hg correlated closely with the age of dolphins, and this suggests that the age or exposure time is a dominant factor for accumulation of these metals.The concentrations o...
