随着社会经济的快速发展,污染物种类和数量不断增加,土壤污染作为环境污染的一个重要组成部分,其污染问题日益突出,生态系统安全受到巨大的威胁。土壤酶是土壤的重要组成部分,具有稳定性,同时对污染物的响应也比较灵敏,因此,土壤酶作为土壤生态毒理学评价的重要指标之一,其活性变化可以指示土壤生态系统的健康状况。该文在总结了国内外现有文献的基础上,开展了土壤酶对重金属、石油烃类污染物、邻苯二甲酸酯类污染物、农药的指示作用的综合分析和论述,以期为土壤酶在土壤生态毒理学中的广泛应用提供参考依据。
With the development of social economy,the type and quantity of pollutants increases constantly.Soil pollution,as an important part of environmental pollution,has been contaminated increasing prominently.The safety of soil ecosystem is facing enormous threat.Soil enzyme is the key component of soil ecosystem and it′s stable and sensitive to contaminants.Therefore,soil enzyme acts as one of the important indicators in soil ecotoxicological evaluation and indicates the health situation of soil ecosystem.In this study,we made the comprehensive analysis and discussion of soil enzyme in indicating of the soil contaminants such as heavy metals,petroleum hydrocarbons,phthalatic acid esters,and farm chemicals so as to provide theoretical support for the widely application of soil enzyme in the soil ecotoxicogical evaluation.
