摘要
土壤重金属污染评价指标主要有 :土壤重金属总含量 ,有效含量 ,土壤酶活性以及植物中毒临界含量等。由于受重金属污染的土壤中往往伴有多种重金属元素及元素之间的交互作用 ,使得临界值的确定更为复杂 。
The evaluation indexes for heavy metals pollution in soils include total concentration of heavy metals in soil,bioavailable concentration of heavy metals in soil,enzyme activity of soil and toxic concentration of plant.Since polluted soils usually were contaminated with more than one element,it is complex to establish the polluted criteria of one heavy metal element for the interactions of heavy metals.At present,the integrated index was commonly used for the evaluation of heavy metal pollution in soils.
