摘要
研究有机配体EDTA对稀土在黑麦草植株中的富集和分布的影响 .结果表明 ,低浓度EDTA可促进稀土在植株中的富集 ,高浓度时抑制 .且稀土主要累积在黑麦草的根部 ,通过食物链对人类影响较小。
The influence of organic ligand EDTA on the bioavailability of REEs in Ryegrass was investigated. When concentration of EDTA was relatively low,it promoted the accumulation of REEs in plants,but it inhibited the REEs' accumulation at high concentration.REEs was mainly accumulated in the roots of the Ryegrass.And influnce on humanity by food chain should be limited.
