镉(Cd)是一种对人和动物具有严重毒性的环境污染物，可引起伊泰病，但目前尚无关于其在野生动物中的污染情况作为环境污染指标的报道。对来自日本9个不同县的85只野生鸟类的肾脏和肝脏中Cd的含量进行了调查，所有野生鸟类肾脏和肝脏中Cd的含量范围分别为ND-174.4和ND-21.2Gg-1干重。Cd在受石油污染的海鸟中的平均含量高于未受污染的海鸟，而且只有受石油污染的海鸟的肾脏和肝脏中的Cd含量之间存在极显著的相关性，而在其他未受污染的海鸟中没有相关性。这些结果表明，野生鸟类反映了应该监测的环境污染水平。
Cadmium (Cd) is an environmental pollutant that has serioustoxicity in humans and animals and causes Itai-Itai disease.However, there is little available information on itscontamination in wildlife as an indicator of environmentalpollution. The Cd contents in the kidney and liver of 85 wildbirds from 9 different prefectures in Japan were investigated.The ranges of the Cd contents in the kidney and liver in allbirds were ND-174.4 and ND-21.2 μg g-1dry wt.,respectively. The mean Cd contents were higher in theoil-contaminated birds than those in the non-contaminated ones.Furthermore, a strong correlation was obtained only between theCd contents in the kidney and those in the liver of theoil-contaminated seabirds and not in the other non-contaminatedones. These results suggest that wild birds reflect the levelof environmental contamination which should be monitored.
