【摘要】 利用盆栽试验研究了连续2年向两种不同土壤:酸性土壤(S1)、碱性土壤(S2)中施加W1(低污染)和W2(高污染)两种污泥后玉米、小麦中重金属Zn、Cd的累积情况,并利用内梅洛综合指数法对植物中Zn、Cd的污染情况进行了评估。结果显示,添加W2污泥的处理中Zn、Cd含量明显高于其他处理,S1土壤中添加污泥后植物中Zn、Cd要普遍高于S2土壤。污泥第一年施用后,玉米中Zn、Cd含量处于安全范围,第二年继续施加后,小麦中Zn、Cd含量属于轻度污染。更多还原

【Abstract】 In order to make sure the Cumulative Risks of Zn,Cd in Crop after sewage sludge application for agricultural.A pot experiment was implemented Over the past 2 years to study the heavy meals accumulation of Zn,Cd in Corn-Wheat.Two kinds of Sewage Sludge,W1(Low contaminated),W2(High contaminated) was applied into two different soil:Acidic Soil(S1),Alkaline Soil(S2) respectively.In the end,N.L.Nemerow comprehensive index was used to assess the pollution of Zn,Cd in the Crops.The results indicated that Zn,Cd content was significantly higher than other treatments after adding W2 sludge.Sludge was added to the S1 soil caused the content of Zn,Cd in the plants is generally higher than to the S2 soil.Sludge in the first year after application,the corn of Zn,Cd content in the safe range,in the second year the concentration reached the Light pollution.更多还原
