Abstract

Milk is one of the most consumed sources among people, especially children. hence, its contamination with heavy metals can pose a serious risk to children. Therefore, this study aimed to measure the lead concentration as one of the most dangerous heavy metals in the raw milk of several major animal husbandries in Tehran province from Iran. A total of 57 raw milk samples were collected from different regions of Tehran province. The lead contents were measured using a graphite furnace atomic absorption spectrometer. To evaluate the risk of the samples and hazard quotient (HQ) were calculated. The results showed that HQ for all samples was lower than 1 which was found within the acceptable level. Because the absorption of Pb is higher in children and this metal has a cumulative property in the body, even its small weekly intake can be dangerous in long-term consumption.

评估从伊朗一些主要奶牛场收集的原料奶中的铅浓度，并评估相关的健康风险

牛奶是人们，尤其是儿童消费最多的牛奶来源之一。因此，它的重金属污染可能对儿童构成严重威胁。因此，本研究旨在测量伊朗德黑兰省几个主要畜牧业原料奶中最危险的重金属之一铅的浓度。从德黑兰省不同地区共收集了57份原料奶样本。用石墨炉原子吸收光谱仪测定了铅的含量。为了评价样品的危险性，计算了危险商(HQ)。结果表明，所有样品的HQ均低于1，在可接受水平内。由于儿童对铅的吸收量较高，而且这种金属在体内具有累积性，因此即使每周摄入量很小，长期摄入也会造成危险。
