厦门几种猛禽体内的重金属分布

测定厦门4种猛禽:草鸮(Tytocapensis)、东方角鸮(Otus sunia)、燕隼(Falco subbuteo)和红隼(Falcotinnunculus)体内铜、锌、铅、镉的含量,研究以上4种元素在猛禽不同组织中的分布规律.结果表明:在草鸮和东方角鸮的5种组织中,羽毛、肌肉、肝脏和心脏的重金属分布规律是Zn＞Cu＞Pb＞Cd,在骨头中为Zn＞Pb＞Cu＞Cd;在燕隼和红隼体内5种组织中的重金属分布规律也为Zn＞Cu＞Pb＞Cd.Cu、Zn、Pb、Cd在猛禽的肝脏、心脏以及骨骼中的含量较高,而在肌肉中的含量较低.猛禽体内的重金属含量主要受环境污染程度、食性以及鸟类富集重金属能力的影响.

Distribution of Heavy Metals in Raptor Birds in Xiamen

In this study,contents of heavy metal,copper(Cu),zinc(Zn),lead(Pb) and cadmium(Cd) were measured in the feather,muscle,bone,liver and heart of four species of raptors,Grass Owl(Tyto capensis),Oriental Scops Owl(Otus sunia),Eurasian Hobby(Falco subbuteo) and Common Kestrel(Falco tinnunculus),collected from Jimei area in Xiamen.The result showed that the heavy metal contents were Zn>Cu>Pb>Cd in the feather,muscle,liver and heart of Grass Owl and Oriental Scops Owl and in the five kinds of organs and tissues of Eurasian Hobby and Common Kestrel,and that the heavy metal contents were Zn>Cu>Pb>Cd in the bone of Grass Owl and Oriental Scops Owl.The copper,zinc,lead and cadmium were higher in the liver,heart and bone,but lower in the muscle of raptor birds.Heavy metal contents in the raptors were mainly affected by environmental pollution,food habit and the ability of collecting heavy metal of the birds.
