Green leafy vegetables are becoming increasingly popular in the developing countries due to their high nutritious value, common availability, and low cost. However, no studies have assessed the health risks associated with consumption of fresh green leafy vegetables. The present study assessed Cd, Cr, and Pb associated health risks in a commonly consumed green leafy vegetable in developing countries, . The Cd, Cr, and Pb concentrations in roots, leaves, and root zone soil of harvested from organic and non-organic cultivations were measured. The results indicated that Cd, Cr, and Pb concentrations in roots and leaves of exceeded the WHO/FAO safe limits for human consumption. Further, bioconcentration factor, soil to root, and root to leaf translocation factors indicated a potential of hyperaccumulating Cd in roots and leaves of . However, the target hazard quotients for Cd, Cr, and Pb were less than 1 indicating negligible health hazard associated with long time consumption of .
由于其高营养价值、普遍可得性和低成本,绿叶蔬菜在发展中国家越来越受欢迎。然而,尚无研究评估食用新鲜绿叶蔬菜相关的健康风险。本研究评估了发展中国家一种常见食用绿叶蔬菜中镉、铬和铅相关的健康风险。测量了从有机和非有机种植中收获的该蔬菜的根、叶和根际土壤中的镉、铬和铅浓度。结果表明,该蔬菜根和叶中的镉、铬和铅浓度超过了世界卫生组织/联合国粮农组织规定的人类消费安全限值。此外,生物富集系数、土壤到根以及根到叶的转运系数表明该蔬菜的根和叶有超积累镉的潜力。然而,镉、铬和铅的目标危害商数小于1,表明长期食用该蔬菜对健康的危害可忽略不计。
