In the present study, the effects of untreated wastewater and associated health risks were assessed in an abundantly consumed vegetable, Luffa cylindrica. In this direction, trace metal accumulations in L. cylindrica samples irrigated with three different water regimes (municipal wastewater, groundwater, and canal water) were determined. The metal levels were defined by atomic absorption spectrophotometer equipped with a graphite furnace and D2 corrector. Trace metal concentrations in L. cylindrica samples were in the range of 7.91–9.01, 3.78–4.22, 0.54–0.63, 39.18–43.27, 15.76–20.82, 29.04–42.49, 6.96–8.24, 5.85–7.72, 4.06–4.39 and 0.18–0.42 mg/kg for Mo, As, Se, Fe, Cu, Zn, Ni, Pb, Cd and Co, respectively. The health risk index values of As, Cd, Pb, Mo, Ni, Se and Co; and pollution load index values of As, Mo, Ni, Cu, Cd and Pb were high, indicating possible phytotoxicity. As had the highest value for the pollution load index suggesting high-risk levels. High levels of some metals could be an alarm call for consumers as the vegetable is irrigated with untreated wastewater.

通过对Luffa(Luffa cylindrica(L.)Roem。)多种灌溉方式的比较分析,对人类健康风险进行评估。

在本研究中,未经处理的废水的影响和相关的健康风险在食用量丰富的蔬菜Luffa cylindrica中进行了评估。在这个方向上,在微量金属积累丝瓜样品灌溉用三种不同水分管理(市政污水,地下水和运河水)进行了测定。金属水平通过配备有石墨炉和D 2校正器的原子吸收分光光度计确定。圆柱状乳杆菌中的痕量金属浓度样品的Mo含量范围为7.91-9.01、3.78-4.22、0.54-0.63、39.18-43.27、15.76-20.82、29.04-42.49、6.96-8.24、5.85-7.72、4.06-4.39和0.18-0.42 mg / kg分别为As,Se,Fe,Cu,Zn,Ni,Pb,Cd和Co。砷,镉,铅,钼,镍,硒和钴的健康风险指数值;砷,钼,镍,铜,镉和铅的污染负荷指数值较高,表明可能具有植物毒性。作为具有最高负荷水平的污染负荷指数,表明高风险水平。蔬菜中未经处理的废水灌溉时,某些金属的含量高可能会引起消费者的警觉。
