Abstract

The consumption of camel milk is gaining popularity in Algeria. This study aimed to determine the concentrations of Lead (Pb), Cadmium (Cd), Nickel (Ni) and Mercury (Hg) in camel milk sold in Southeast Algeria and assess the potential health risks associated with its consumption. 120 samples of camel milk were collected from 10 farms located near the roads in the south of Algeria. Metals were measured using an atomic absorption spectrophotometer with a graphite furnace and Target Hazard Quotients (THQs) were calculated. The mean concentrations were 0.026 ± 0.013 mg/kg, 0.001 ± 0.0002 mg/kg, 0.017 ± 0.002 mg/kg and 0.0005 ± 0.0002 mg/kg for Pb, Cd, Ni and Hg. The THQ was higher for children, suggesting health risks associated with consumption of camel milk for this age group (p < .001). The primary contribution of this study is the establishment of a database on toxic metal levels in camel milk, which can be valuable to manage possible risk associated with metals in milk.

阿尔及利亚撒哈拉沙漠北部出售的生骆驼奶中的有毒金属含量。

骆驼奶在阿尔及利亚越来越受欢迎。本研究旨在确定在阿尔及利亚东南部销售的骆驼奶中铅 (Pb)、镉 (Cd)、镍 (Ni) 和汞 (Hg) 的浓度，并评估饮用骆驼奶可能带来的健康风险。从阿尔及利亚南部公路附近的 10 个农场收集了 120 份骆驼奶样本。使用带石墨炉的原子吸收分光光度计测量了金属含量，并计算了目标危害商数 (THQ)。铅、镉、镍和汞的平均浓度分别为 0.026 ± 0.013 毫克/千克、0.001 ± 0.0002 毫克/千克、0.017 ± 0.002 毫克/千克和 0.0005 ± 0.0002 毫克/千克。儿童的 THQ 值较高，表明饮用骆驼奶对这一年龄组的儿童有健康风险（p

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
