Diet based on cereal, vegetables, oleaginous and dried fish are providing essential metallic elements. It can be also a source of exposure to toxic metallic elements. The aims of this study were to evaluate the contents on nine metallic trace elements (Fe, Zn, Mn, Co, Cd, Pb, Cu, Ni, Cr) in some major raw foodstuffs including rice, maize, peanut, tomato and dried fish in Burkina Faso and assess the health risk of these elements. Two hundred twenty-two samples were collected and analyzed by atomic absorption spectrometry. The health risk assessment was based on the United States Environment Protection Agency (USEPA) model. Iron and Zinc were the elements with the highest concentrations in the investigated foodstuffs. The iron highest median value (68.80 mg/kg) was observed in dried fish followed by maize (43.09 mg/kg) and peanuts (28.92 mg/kg). Rates of 77.95%, 66.66% and 32.5% obtained respectively fro tomato, maize and rice samples were above the maximum limit of lead set by Codex Alimentarius while 47.6%, 71.16% and 0% of maize, tomato and rice samples respectively have shown concentration above the maximum limit of cadmium. Chromium had shown higher contribution rate to the maximum daily intake of 167.11%, 34%, 2% and 8.53% for rice, maize and peanut respectively. A non-cancer risk situation has been observed on rice, maize and peanut consumption. None of the index risk values was above the threshold set by USEPA.
以谷物、蔬菜、油类和干鱼为基础的饮食能提供必需的金属元素。它也可能是接触有毒金属元素的一个来源。本研究的目的是评估布基纳法索一些主要生食（包括大米、玉米、花生、番茄和干鱼）中九种金属微量元素（铁、锌、锰、钴、镉、铅、铜、镍、铬）的含量，并评估这些元素的健康风险。收集了222个样本，并用原子吸收光谱法进行分析。健康风险评估基于美国环境保护局（USEPA）模型。铁和锌是被调查食品中浓度最高的元素。在干鱼中观察到铁的最高中位数（68.80毫克/千克），其次是玉米（43.09毫克/千克）和花生（28.92毫克/千克）。番茄、玉米和大米样本中分别有77.95%、66.66%和32.5%的铅含量高于食品法典委员会设定的铅最大限量，而玉米、番茄和大米样本中分别有47.6%、71.16%和0%的镉含量高于镉最大限量。铬对大米、玉米和花生的最大日摄入量的贡献率分别较高，为167.11%、34%、2%和8.53%。食用大米、玉米和花生时观察到非癌症风险情况。没有一个指数风险值超过USEPA设定的阈值。
