摘要: 重金属铅不是作物生长的必需元素,而是一种对作物有积累性危害的污染物质。铅一旦污染土壤,很难降解、去除。铅对土壤污染后,可导致农产品产生残毒,并可通过土壤作物系统进入食物链,危害人体健康。本文就农田土壤作物系统中铅的来源、积累与迁移等研究进行综述,旨在提醒人们关注铅的危害,采取积极措施提早预防。

Abstract: Lead is not a necessary element to crop growth but a pollutant with accumulation problems. If lead is absorbed by soil, it will be difficult to be removed. Polluted soil will result in toxin in agricultural product and lead can enter into food chain by soil-crop system, which will hurt human beings. This paper summarized the source of lead, accumulation and migration in agricultural soil-crop system in order to remind people to pay attention to the harm of lead and prevent it early.
