土壤是农业生产的基础,随着社会的进步和经济的高速发展,越来越多的污染物排入土壤,其中重金属所占的比例逐渐增大,成为土壤治理的主要对象.农用地重金属污染不仅会导致作物产量降低,而且重金属会随着食物链在人体内积累,对人体产生极大的危害,因此重金属污染修复迫在眉睫.文章综述了农用地重金属污染现状、来源以及各种修复技术,分析了不同修复技术的优势及不足,为运用联合修复技术控制农用地重金属污染提供一定的借鉴与思路.
The Situation and Remediation Methods of Heavy Metal Pollution in Agricultural Land
Soil is the basis of agricultural production,but more and more pollutants are discharged into the soil with the rapid social progress and economic development.Among all pollutants,the proportion of heavy metal is gradually increasing to an predominant part in soil management.The heavy metals in soil could not only reduce crop yield,but also accumulate in human body along with the food chain,causing serious health problems.Therefore,the remediation of heavy metal pollution is of great necessity.In this work,the status and sources of heavy metal pollution,as well as various remediation technologies,were reviewed.Meanwhile,the advantages and disadvantages of different remediation technologies were analyzed,which provide references for application of combined remediation technologies to control heavy metal pollution in farmland soil.
