Abstract

In this study bio-accumulated levels of Cd, Cr, Cu, Ni and Pb in seven most popular North Indianleafy vegetables, spinach (Spanacia oleracea), bathua (Chenopodium album), chaulayi (Amranthspinosus), mustard (Brassica nigra), rayi (Brassica juncea), radish leaves (Raphanus sativus) andfenugreek (Trigonella foenum-graecum) collected from local venders were evaluated. The dailyintakes of metals (DIM) through consumption of these leafy vegetables were computed for testedmetals to quantify consumer health risk index (HRI). For the purpose of comparison, vegetablescultivated under ideal conditions in a walled garden were also tested for studied metals. The orderand accumulated levels of metals in leafy vegetables varied as: Pb (2.16-3.16) > Cr (1.54-2.84) > Cu(0.39- 0.94) > Ni (0.38-0.78) > Cd (0.33-0.51). However, the accumulated levels of tested metals invegetables cultivated in the walled garden were much lower and varied as: Pb (1.11-1.46) > Cr (0.66-1.22) > Cu (0.21- 0.42) > Ni (0.22-0.33) > Cd (0.19- 0.29). The order of computed consumers health riskindex (HRI) due to tested metals on dietary intake of studied vegetables collected from localvenders varied as: Pb (229.5 â 335.7) > Cd (140.2 â 216.7) > Ni (8.74- 14.73) > Cu (4.49- 10.82) > Cr(0.473- 0.872).

北印度一些叶菜中重金属的生物累积及其膳食摄入对消费者健康风险的量化

在本研究中，对从当地供应商处采集的七种北印度最受欢迎的蔬菜，即菠菜（Spanacia oleracea）、芭蕉（Chenopodium album）、芥菜（Brassica nigra）、芥子（Brassia juncea）、萝卜叶（Raphanus sativus）和胡芦巴（Trigonella foenum graecum）中的Cd、Cr、Cu、Ni和Pb的生物累积水平进行了评估。为了量化消费者健康风险指数（HRI），计算了通过食用这些叶菜而产生的每日金属摄入量（DIM）。为了进行比较，还对在理想条件下在围墙花园中种植的蔬菜进行了金属测试。叶菜中金属含量的顺序和累积水平依次为：Pb（2.16-3.16）>Cr（1.54-2.84）>Cu（0.39-0.94）>Ni（0.38-0.78）>Cd（0.33-0.51），在围墙花园中种植的测试金属可种植物的累积水平要低得多，变化为：Pb（1.11-1.46）>Cr（0.66-1.22）>Cu（0.21-0.42）>Ni（0.22-0.33）>Cd（0.19-0.29）（140.2â216.7）>Ni（8.74-14.73）>Cu（4.49-10.82）>Cr（0.473-0.872）。
