单一及复合绿色螯合剂对苋菜镉、砷的富集影响
|
摘要
为了探究绿色螯合剂的复合施用在植物修复中的作用效果。在Cd、As污染菜地中施加小分子有机酸OA(草酸)、TA(酒石酸)、MA(苹果酸)和氨基酸基螯合剂IDS(亚氨基二琥珀酸)、PASP(聚天冬氨酸),并将二者进行复配,探究其对苋菜(Amaranthus mangostanus L.)重金属富集的影响。结果表明:苋菜地下部分Cd、As积累量均显著高于地上部分(P<0.05);从苋菜对Cd、As的富集系数来看,PASP、IDS-OA和IDS-TA处理强化了Cd、As的植物修复;所有处理不对Cd的转运产生抑制作用,其中IDS-OA处理的As转运系数显著高于对照组,高出1.88倍。考虑到绿色螯合剂成本和苋菜生物量,认为IDS-OA可以同时提高苋菜对Cd、As富集量,可为广东Cd、As污染菜地植物修复提供理论依据。
The paper aims to explore the effects of adding complex green chelates on phytoremediation. Small molecular organic acids OA(Oxalic acid), TA(Tartaric acid), MA(Malic acid) and amino acid chelating agents IDS(Iminodisuccinic acid sodium salt) and PASP(Polyaspartic acid) were applied in Cd and As contaminated vegetable fields, and the two were combined to explore the influence on the heavy metal enrichment in Amaranthus mangostanus L. The results showed that: the accumulation of Cd, As in the underground part was higher than that in aerial part(P<0.05); according to the BCF(bioaccumulation coefficients) of Cd and As,PASP, IDS-OA and IDS-TA enhanced the phytoremediation of Cd and As; the TF(transfer factor) of Cd did not decrease in all treatments, and the TF of As treated by IDS-OA was 1.88 times higher than that of the control. Considering the cost of green chelates and the biomass of Amaranthus mangostanus L., IDS-OA can simultaneously increase the enrichment of Cd and As in Amaranthus mangostanus L., which can provide a basis for phytoremediation of vegetable fields contaminated by Cd and As in Guangdong.
