摘要:
垃圾堆肥拌施CaCO3对蔬菜中重金属的累积效应试验结果显示:单施垃圾肥会增加蔬菜中重金属的累积量,但若施垃圾堆肥同时拌施CaCO3(按施垃圾堆肥量的0.5%或1%),则可有效地降低蔬菜中重金属的累积水平。与单施垃圾堆肥相比,拌施CaCO3能使番茄中Pb含量下降29%-41%;Cr下降5%-46%,Cd下降9%-42%;Cu下降2%-24%;AS下降4%-60%;有的元素如Pb和Cd甚至能降到本底值(即不施垃圾肥者)以下。青菜中Pb、Cu、As的含量下降较明显。试验还显示:施垃圾堆肥拌施CaCO3,土壤中重金属可提取总量低于单施垃圾堆肥者。
Abstract:
The results indicated that garbage compost application could increase heavy metal accumulation in vegetables.However,adding CaCO3 (0.5% or 1% of garbage compost) could effectively decrease the accumulation.The addition of CaCO3 could decrease heavy metal levels in tomato as: Pb by 29%-41%,Cr 5%-46%,Cd 9%-42%,Cu 2%-24% and As 4%-60%.Certain heavy metals,such as Pb,Cu and As could even be decreased below the level without applying garbage compost.In green vegetables the level of heavy metals,Pb,Cu and As was also significantly decreased after applying garbase compost with CaCO3.It was also indicated that the total amount of extractable heavy metals was much lower in soil applied with garbage compost with CaCO3 than in that with compost alone.
