With the aim of knowing the concentration and distribution of essential and nonessential metals in selected tissues of whales, analysis of Cd, Cu, Fe, Mn, Pb and Zn were carried out in kidney, liver and muscle of the gray whale Eschrichtius robustus and the sperm whale Physeter catodon. Whales were found stranded in the southeast Gulf of California. Individuals were in a juvenile stage; mean length of whales was 9.3 m for E. robustus and 7 m for P. catodon. Sequence of metal concentrations was Fe>Zn>Cu>Mn>Cd>Pb in E. robustus, and Fe>Zn>Cu>Cd>Mn>Pb in P. catodon. In E. robustus, highest concentrations of Cu, Mn, Pb and Zn (17.2, 19.6, 0.9 and 388 microg g(-1), respectively) were measured in liver, Cd (5.7 microg g(-1)) in kidney and Fe (1009 microg g(-1)) in muscle. In P. catodon, the highest levels of Cu, Fe and Pb (48.6, 5200 and 4.2 microg g(-1), respectively) were found in liver, Cd and Zn (94 and 183 microg g(-1)) in kidney and Mn (8 microg g(-1)) in muscle. Metal concentrations reported here were not considered to contribute to the stranding of specimens.
为了解必需金属和非必需金属在鲸鱼特定组织中的浓度和分布情况,对灰鲸(Eschrichtius robustus)和抹香鲸(Physeter catodon)的肾脏、肝脏和肌肉中的镉(Cd)、铜(Cu)、铁(Fe)、锰(Mn)、铅(Pb)和锌(Zn)进行了分析。这些鲸鱼是在加利福尼亚湾东南部搁浅被发现的。个体处于幼年期;灰鲸的平均体长为9.3米,抹香鲸为7米。灰鲸体内金属浓度顺序为Fe>Zn>Cu>Mn>Cd>Pb,抹香鲸体内为Fe>Zn>Cu>Cd>Mn>Pb。在灰鲸中,肝脏中铜、锰、铅和锌的浓度最高(分别为17.2、19.6、0.9和388微克/克),肾脏中镉的浓度为5.7微克/克,肌肉中铁的浓度为1009微克/克。在抹香鲸中,肝脏中铜、铁和铅的含量最高(分别为48.6、5200和4.2微克/克),肾脏中镉和锌的含量为94和183微克/克,肌肉中锰的含量为8微克/克。此处报告的金属浓度不被认为是导致样本搁浅的原因。
