Abstract

The aim of the current research was to evaluate the heavy metals contamination in Kurdish rice from the main rice-producing areas in Kurdistan and its health risk assessment. The Kurdish rice samples were collected from different locations and the concentration of heavy metals was measured by using Inductively Coupled Plasma-optical emission spectrometry (ICP-OES). The Estimated Daily Intake (EDI) was also calculated to evaluate the potential health risk assessment for the Kurdish local population through rice consumption. The mean EDI values from the rice consumption of most Kurdish rice samples were significantly higher than the safe limits set by FAO/WHO. The heavy metals were detected in the descending order Fe > Mn > Zn > Cu > Cr > Ni > As > Co > Cd in the rice samples. The results demonstrate that Kurdish rice from the investigated region has been contaminated with some heavy metals (As, Cr, Mn and Ni) which is probably linked to the used wastewater for irrigation, fertilisers and soil contamination. Overall, the local population's health might be at risk due to the combination of various metals. Therefore, strict food safety regulations are recommended for cereal crops, as well as, regular monitoring of soil contamination, water quality, application of fertilisers and pesticides in the agricultural areas in Iraqi Kurdistan.
伊拉克库尔德斯坦地区种植的部分库尔德水稻短粒中重金属浓度及其健康风险评估。
本研究的目的是评估库尔德斯坦主要水稻产区库尔德水稻中的重金属污染及其健康风险评估。从不同地点采集库尔德水稻样品,并使用电感耦合等离子体发射光谱法(ICP-OES)测量重金属浓度。还计算了估计每日摄入量(EDI),以评估通过大米消费对库尔德当地人口的潜在健康风险评估。大多数库尔德大米样本的大米消费的平均EDI值明显高于粮农组织/世界卫生组织设定的安全限值。水稻样品中重金属含量的高低顺序为Fe>Mn>Zn>Cu>Cr>Ni>As>Co>Cd。结果表明,调查地区的库尔德水稻受到了一些重金属(As、Cr、Mn和Ni)的污染,这可能与灌溉废水、化肥和土壤污染有关。总的来说,由于各种金属的结合,当地居民的健康可能面临风险。因此,建议对谷物作物制定严格的食品安全法规,并定期监测伊拉克库尔德斯坦农业区的土壤污染、水质、化肥和农药的使用情况。
