摘要

本研究的目的是对巴卡特普尔地区(Manohara、Nagadesh、Bode、Hanumanghat、Sipadol、Tathali和Gundu)不同地区土壤和蔬菜中的重金属(Cu、Zn、Pb、Cd)进行评估。这项研究中的多叶蔬菜有菠菜、花椰菜、胡萝卜、卷心菜和阔叶芥菜。结果表明，巴喀特浦尔地区植物和土壤中重金属的富集程度依次为Zn> Cu>Pb> Cd，菠菜对重金属的富集程度高于其他蔬菜。地质堆积等级(Igeo)表明，哈努曼哈特、马诺哈拉、纳加德什和博德的农业土壤镉污染程度中等。《科学世界》，2014年9月，第12卷，第12期，第48-55页

HEAVY METAL POLLUTION OF AGRICULTURAL SOILS AND VEGETABLES OF BHAKTAPUR DISTRICT, NEPAL

The aim of this study was carried out to assess heavy metals (Cu, Zn, Pb, Cd,) in soils as well as vegetables of respective place of the Bhakatpur District (Manohara, Nagadesh, Bode, Hanumanghat, Sipadol, Tathali and Gundu). The leafy vegetables under this study were Spinach, Cauliflower, Carrot, Cabbage and Broad leaf mustard. The results showed that the concentration of heavy metals in the plants and soils from the Bhakatpur was proportional in the order Zn> Cu>Pb> Cd. Spinach showed the extremely high accumulation tendency towards the heavy metals compare to other vegetables. The geo-accumulation class (Igeo) indicates that the agricultural soil of Hanumanghat, Manohara, Nagadesh and Bode are moderately contaminated of Cd.
