Trace metals contamination has recently been a major issue due to its damaging effects on public health and environmental receptors. This study focussed on the health risk assessment of trace metals (As, Pb, Cr, and Ni) associated with the direct intake of some selected food crops (namely cocoyam and plantain) at Abuakwa South Municipal, Ghana. The food crops and soil samples were selected randomly from three reclaimed mined sites and one non-mining site in the study area. Results from the trace metal concentration analyses in the soil samples showed that As, Cr, and Ni were above the control. The daily intake of metals (DIM), target hazard quotient (THQ), and carcinogenic risk (CR) assessments of health risks accompanied by the continuous ingestion of the selected food crops polluted through these trace metals were evaluated. 0.23 mg/kg and 0.05 mg/kg, 0.11 mg/kg and 0.02 mg/kg, 0.78 mg/kg and 0.65 mg/kg, and 0.23 mg/kg and 0.09 mg/kg were recorded for As, Cr, Ni, and Pb in that order in the cocoyam and plantain, respectively. The As and Pb concentrations in the food crops were above the WHO recommended limits. This implies that individuals within the vicinity are exposed to high levels of As and Pb through food intake which could result in varying health implications. The DIM and THQ for the studied trace metals were below their permissible limits suggesting that there is a tolerable non-carcinogenic adverse health risk level for adults and children within the studied area. In addition, the lifetime probability of contracting cancer by ingesting Ni, Pb, and Cr in plantain grown in the study area is high. It is recommended that regular monitoring of these trace metals in food crops be carried out in preventing their excessive accumulation.

加纳阿布瓦南市选定粮食作物中痕量金属的健康风险评估

由于其对公共健康和环境受体的破坏性影响,微量金属污染最近已成为一个主要问题。本研究的重点是对加纳阿布瓦克瓦南市某些特定粮食作物(即椰子和车前草)的直接摄入相关的痕量金属(As、Pb、Cr 和 Ni)的健康风险评估。粮食作物和土壤样品是从研究区的3个复垦矿区和1个非矿区中随机抽取的。土壤样品中痕量金属浓度分析的结果表明,As、Cr 和 Ni 高于对照。对伴随持续摄入被这些微量金属污染的选定粮食作物的健康风险的每日金属摄入量 (DIM)、目标危害商数 (THQ) 和致癌风险 (CR) 评估进行了评估。0.23 毫克/公斤和 0. As、Cr、Ni 和 Pb 依次为 05 mg/kg、0.11 mg/kg 和 0.02 mg/kg、0.78 mg/kg 和 0.65 mg/kg,以及 0.23 mg/kg 和 0.09 mg/kg。分别是椰子和车前草。粮食作物中的 As 和 Pb 浓度高于 WHO 推荐的限值。这意味着附近的人通过食物摄入接触到高水平的砷和铅,这可能导致不同的健康影响。所研究的痕量金属的 DIM 和 THQ 低于其允许限度,表明研究区域内的成人和儿童存在可容忍的非致癌不良健康风险水平。此外,摄入研究区种植的车前草中的 Ni、Pb 和 Cr 后患癌症的终生概率很高。
