This study was designed to evaluate heavy metal status in commonly consumed foodstuffs collected from two divisional cities, viz., Chottogram and Mymensingh of Bangladesh and to assess potential human health risks through the consumption of those foodstuffs. A total of 90 food samples were analyzed for Cu, Zn, Ni, Pb, Mn, and Fe contents by an atomic absorption spectrophotometer. The calculated per capita per day dietary intakes of Cu and Mn from rice and Mn’s same value through spinach consumption in both cities were higher than the recommended daily allowances (RDA) for an adult human. Similarly, the computed daily metal intake (DMI) values of Pb for both males and females were also higher than the upper tolerable intake level (UTIL) through the consumption of rice collected from Mymensingh city. The average calculated hazard index (HI) values for males and females due to dietary intake of rice were 47.67 and 93.30 in Chottogram city and 97.98 and 192.04 in Mymensingh city, respectively. The present study identified rice as the most contaminated food item, followed by spinach, brinjal, and lentil. Still, dietary intakes of beef, broiler, and fish samples collected from both the cities were found as safe or less hazardous. Among the individual metals, Mn was the most dominant metal present in different foodstuffs collected from both the cities and contributed significant risk to the people. Finally, the study concluded that Bangladesh’s food consumption patterns should be changed and advised to incorporate more proteins in regular diet charts by reducing carbohydrates.

通过从孟加拉国两个分区城市收集的普通食品消费对重金属的人类健康风险评估

这项研究旨在评估从两个部门城市(即孟加拉国的Chottogram和Mymensingh)收集的常用食品中的重金属状况,并评估通过食用这些食品对人体健康的潜在风险。用原子吸收分光光度计分析了总共90个食品样品中的铜,锌,镍,铅,锰和铁的含量。在两个城市中,通过计算得出的人均每天从稻米中摄取的铜和锰的膳食摄入量以及通过菠菜消费而获得的锰的相同价值均高于成年人的建议每日摄入量(RDA)。同样,通过消耗从迈门辛格市收集的大米,男性和女性的每日铅的金属摄入量(DMI)值也高于最高容许摄入量(UTIL)。图表中,因进食稻米而引起的男性和女性的平均计算危害指数(HI)值分别在米图辛格市和米门辛格市分别为47.67和93.30,在迈门辛格市为97.98和192.04。本研究确定大米是最受污染的食品,其次是菠菜,茄子和小扁豆。尽管如此,从这两个城市收集的牛肉,肉鸡和鱼类样品的饮食摄入被认为是安全的或危害较小的。在每种金属中,锰是在两个城市收集的不同食品中含量最高的金属,对人们构成了重大风险。最后,研究得出结论,孟加拉国的食物消费方式应予以改变,并建议通过减少碳水化合物在常规饮食图中添加更多蛋白质。图表城市分别为30,迈门辛​​格市分别为97.98和192.04。本研究确定大米是最受污染的食品,其次是菠菜,茄子和小扁豆。尽管如此,从这两个城市收集的牛肉,肉鸡和鱼类样品的饮食摄入被认为是安全的或危害较小的。在每种金属中,锰是在两个城市收集的不同食品中含量最高的金属,对人们构成了重大风险。最后,研究得出结论,孟加拉国的食物消费方式应予以改变,并建议通过减少碳水化合物在常规饮食图中添加更多蛋白质。图表城市分别为30,迈门辛​​格市分别为97.98和192.04。本研究确定大米是最受污染的食品,其次是菠菜,茄子和小扁豆。尽管如此,从这两个城市收集的牛肉,肉鸡和鱼类样品的饮食摄入被认为是安全的或危害较小的。在每种金属中,锰是在两个城市收集的不同食品中含量最高的金属,对人们构成了重大风险。最后,研究得出结论,孟加拉国的食物消费方式应予以改变,并建议通过减少碳水化合物在常规饮食图中添加更多蛋白质。从这两个城市收集的牛肉,肉鸡和鱼的膳食摄入被发现是安全的或危害程度较小。在每种金属中,锰是在两个城市收集的不同食品中含量最高的金属,对人们构成了重大风险。最后,研究得出结论,孟加拉国的食物消费方式应予以改变,并建议通过减少碳水化合物在常规饮食图中添加更多蛋白质。从这两个城市收集的牛肉,肉鸡和鱼的膳食摄入被发现是安全的或危害程度较小。在每种金属中,锰是在两个城市收集的不同食品中含量最高的金属,对人们构成了重大风险。最后,研究得出结论,孟加拉国的食物消费方式应予以改变,并建议通过减少碳水化合物在常规饮食图中添加更多蛋白质。
