Abstract

In Erbil city the farmers used both wastewater and well water for irrigation pupose. An inductively coupled plasma ICP was used to analyze heavy metals., including silver (Ag), aluminum (Al), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), zinc (Zn), chrome (Cr), cadmium (Cd), and arsenic (As), in wastewater, well water, agricultural soils, and vegetables (Chard, Celery, Arugula, Leek and Dill), as well as the health risks they pose in Erbil. Bio-concentration factor (BCF), daily intake (DI), Target Hazard Quotient (THQ), and carcinogenic risks (CR) were calculated to determine health concerns. Overall, metals were found in water, soil, and vegetables. The following is a rundown of the tendencies in these metals' Ni 1. As, Cd, and Cr's CR values above 10-4. These results show that local farmers' habit of irrigating vegetables with untreated wastewater and well water has generated heavy metal deposition in the soils, which is absorbed by vegetables and poses a health concern to the local people.

埃尔比勒居民每天通过污水和井水灌溉的蔬菜消耗重金属

在埃尔比勒市，农民使用废水和井水进行灌溉。采用电感耦合等离子体ICP对重金属进行了分析。，包括银(Ag)、铝(Al)、铁(Fe)、锰(Mn)、镍(Ni)、铅(Pb)、锌(Zn)、铬(Cr)、镉(Cd)和砷(As)，在废水、井水、农业土壤和蔬菜(甜菜、芹菜、芝麻菜、韭菜和莳荽)中，以及它们在埃尔比勒造成的健康风险。计算生物浓度因子(BCF)、每日摄入量(DI)、目标危害商(THQ)和致癌风险(CR)以确定健康问题。总的来说，在水、土壤和蔬菜中都发现了金属。以下是这些金属的Ni<Ag <锌& lt;Cr & lt;Mn & lt;Cd & lt;& lt;铁& lt;艾尔& lt;废水和井水中的Pb和As<Ag <Cr<Fe<Cd<Ni<Zn<Mn<Al<土壤中的铅。蔬菜样品中As、Cd、Cr、Al、Pb、Ni、Mn、Fe、Zn、Ag的平均值分别为0.74 ~ 13.90、12.90 ~ 41.70、2.59 ~ 30.40、573 ~ 1810、93 ~ 292、2.44 ~ 31.65、23.10 ~ 116、138 ~ 448、13.70 ~ 40.13和1.55 ~ 14.91，废水和井水灌溉的甜菜、芝麻菜和芹菜中Cd、Pb和Mn均超过WHO/FAW成人安全限值。As、Cd和Pb的thq值除位点2和4外均大于1。甜菜植株1、4、6位点的Al和Mn均存在thq;1. As、Cd、Cr的Cr值大于10-4。这些结果表明，当地农民使用未经处理的废水和井水灌溉蔬菜的习惯导致土壤中重金属沉积，这些重金属被蔬菜吸收，对当地居民的健康造成了影响。
