摘　　要：采用ICP-AES电感耦合等离子光谱仪对来源于北京地区的长耳鸮(Asio otus)和雕鸮(Bubo bubo)体内的金属元素Cr,Pb,Co,Cd,Ni和Mn含量进行了检测。长耳鸮各组织中的重金属含量,仅Cd(p=0.000)在不同组织中有显著性差异,雕鸮各组织中Cr(p=0.002),Ni(p=0.000),Co(p=0.009),Cd(p=0.010),Mn(p=0.002)在不同组织中有显著性差异。Cr在长耳鸮的肾脏中含量最高,而在雕鸮各组织中则是在脑中的含量最高。Cd的含量在各种金属中是最少的,而Mn的含量最高。两种鸮类中,Ni在长耳鸮胸羽中的含量高于其他组织,而在雕鸮体内则是在脑中的含量高于其他组织。Co在长耳鸮的肾脏中含量最高,雕鸮的脑中含量最高,肾脏次之。并且实验还发现无论是长耳鸮还是雕鸮,背羽都是检测重金属的最佳选择。A preliminary study on 6 metal contents was extracted from 10 eagle owls（Bubo bubo）and 10 long-eared owls（Asio otus）in Beijing with Jobin Yvon-ULTIMA inductively coupled plasma.The heavy metal elements detected were included Chromium,Lead,Cobalt,Manganese,Nickel and Cadmium.And Cd（p=0.000）is the only element which had significant difference in different tissues of long-eared owls,but the elements of Cr（p=0.002）,Ni（p=0.000）,Co（p=0.009）,Cd（p=0.010）,Mn（p=0.002）had significant difference in different tissues of eagle owls.The highest content of Cr in long-eared owls＇ tissues was from kidney,but in eagle owl was from brain.The lowest content of all the detected elements was Cd and the highest was Mn.The content of Ni in brain was higher than the other tissues in eagle owls,but the tissues had the highest content of Ni was thoracic feathers in long-eared owls.The content of Co was highest in long-eared owls＇ kidneys,but lowest in eagle owls＇ brains.This experiment also found that using back feathers was the best choice for the heavy metal detecting of long-eared owls and eagle owls.
