| 摘 要： | 用盆栽试验,研究了污泥对生菜、萝卜产量和重金属、硝酸盐和亚硝酸盐积累的影响.结果表明,污泥可明显增加生菜和萝卜产量;当污泥施用量为土壤干重的1%时,生菜和萝卜中重金属Zn、Cd、Cr、Cu、Pb含量及硝酸盐和亚硝酸盐含量均符合国家食品卫生标准;当污泥施用量为土壤干重的3%时,生菜中重金属Cd含量超标,萝卜中亚硝酸盐含量超标,超标率分别达20%、15%.

| Abstract: | Pot experiment was used to study the effect of sewage sludge on head lettuce and radish yields as well as heavy metals,nitrate and nitrite accumulation in vegetables.The results showed that sewage sludge increased head lettuce and radish yields.And heavy metals(Zn,Cd,Cr,Cu and Pb)contents in the esculent part of head lettuce and radish met the required national control standard at 1% dosage of sewage sludge in dry soil.But when the dosage was up to 3%,the cadmium content in head lettuce and nitrite content in radish exceeded the national control standard,which were 20% and 15% over limit rate,respectively. |
