Abstract

This study was carried to investigate the contamination levels of heavy in food crops (rice, wheat, maize, and pulses) grown in the vicinity of the mica mine in Jharkhand, India. Except for Pb and Zn in select places, the metal concentrations in the food crops were below the maximum allowed levels for food in India. The principal component analysis identified three components that accounted for 71.3 % of the variability in the data. The components that were retrieved indicated that soil, irrigation water, and air dust deposition could be the sources of metals in the food crops. The estimated daily intake (EDI) and target hazard quotient (THQ) of food crop consumption were used to highlight the potential health concerns associated with metal exposure. In several samples, local individuals' daily intakes of Pb was greater than the WHO's recommended daily intakes of these heavy metals. Taking into account the geometric mean of metal concentrations in food crops samples from the, the hazard index (HI) for the consumers was 10.28 which is far above unity. Pb, Co, and As were the primary contributors to the potential non-carcinogenic risk. The HI ranged from 7.22 to 18.29 across different locations, indicating a significant health risk to the consumers of locally grown food crops in the vicinity of the mica mining areas.

印度恰尔肯德邦云母矿区谷物和豆类中金属污染对人类健康的风险评估
这项研究旨在调查印度恰尔肯德邦云母矿附近种植的粮食作物(水稻、小麦、玉米和豆类)中的重金属污染水平。除个别地方的铅和锌外,粮食作物中的金属浓度均低于印度食品允许的最高水平。主成分分析确定了三个成分,占数据变异性的 71.3%。这些成分表明,土壤、灌溉水和空气灰尘沉积可能是粮食作物中金属的来源。粮食作物消费的估计日摄入量(EDI)和目标危害商数(THQ)被用来强调与金属暴露相关的潜在健康问题。在多个样本中,当地人的每日铅摄入量高于世界卫生组织推荐的这些重金属的每日摄入量。考虑到粮食作物样本中金属浓度的几何平均值,消费者的危害指数(HI)为 10.28,远远高于统一值。铅、钴和砷是造成潜在非致癌风险的主要因素。不同地点的危害指数从 7.22 到 18.29 不等,表明云母矿区附近当地种植的粮食作物对消费者的健康有重大风险。
