Cheeses are an important source of essential elements. Nevertheless, the level of some metals could pose a health risk. Therefore, the concentration of trace elements and toxic metals (Cr, Cu, Li, Ni, Sr, Pb, Cd, and Al) has been determined in artisanal cheeses from different geographical locations, and the intake of these metals from cheese consumption has been evaluated. The metal concentration was determined in a total of 90 cheese samples from different locations by using inductively coupled plasma atomic emission spectroscopy. The highest concentration of Al (35.1 ± 4.42 mg/kg, wet weight) was found in artisanal cheeses from Zamora (Spain), followed by Sr (6.85 ± 0.35 mg/kg, wet weight) in artisanal cheeses from Cadiz (Spain). A daily consumption of 23.2 g of cheese provides a significant dietary contribution for Al of 0.82% of its tolerable weekly intake of 1 mg/kg of body weight per week. Canary Islands cheeses have a higher metal content than the non-Canary cheese, which could be because of the volcanic characteristics of the island soils. The intake of toxic metals and trace elements poses no risk to the health of adults.
奶酪是重要的必需元素来源。然而，一些金属的含量可能会对健康造成风险。因此，我们对来自不同地理区域的手工奶酪中的微量元素和有毒金属（Cr、Cu、Li、Ni、Sr、Pb、Cd 和 Al）的浓度进行了测定，并评估了通过食用奶酪摄入这些金属的情况。通过电感耦合等离子体原子发射光谱法，共对 90 个来自不同地区的奶酪样本中的金属浓度进行了测定。在来自西班牙 Zamora 的手工奶酪中发现了最高浓度的 Al（35.1 ± 4.42 mg/kg，湿重），其次是来自西班牙 Cadiz 的手工奶酪中的 Sr（6.85 ± 0.35 mg/kg，湿重）。每日食用 23.2 克奶酪可显著摄入 Al，占其每周耐受摄入量（1 毫克/千克体重/周）的 0.82%。与非加那利群岛奶酪相比，加那利群岛奶酪的金属含量更高，这可能是由于该岛土壤的火山特征所致。摄入有毒金属和微量元素不会对成年人的健康造成风险。
