摘要
鸟类是食物链中的高级消费者。环境中的重金属可通过食物链传递并在鸟体内富集,受重金属污染的鸟的体色、体形和行为发生变化,鸟体组织中的重金属浓度反映了鸟类所处环境背景中的重金属浓度的高低,因此可以用鸟类作为监测环境的指示生物来监测重金属污染。文章对重金属在鸟体内富集的一些特点、用鸟类作环境监测的指示生物时应注意的问题进行了分析,对今后的研究进行了展望,期望今后用鸟类监测环境污染的方法能在我国得到广泛应用。
Birds are the top consumers in the ecosystem and the tissues of birds can accumulated heavy metals from their ambience or foods. Concentrations of heavy metals in tissues of birds reflect environmental background values of heavy metals. Asa resalt the tissues of birds are widely used in monitoring environmental pollution. But, concentrations of heavy metals in tissues of birds vary with environmental background, foods, bird species, bird sex, bird ages, kinds of tissues etc. This paper discussed the characteristics of heavy metal accumulation in the tissues of birds. These characteristics are considered when using birds as bioindicator of environmental monitoring. Some topics of study on birds as bioindicator in the future are put forward in the paper as well.
