For most people diet is the main route of exposure to trace metals, so information about dietary intake is also important to assess risks to human health for these elements. The purpose of this study was to determine the levels of Pb in the foods and drinks of highest consumption in the authors' our community to estimate daily intakes of Pb for each of the seven Canary Islands. Four hundred and twenty samples were analyzed using GFAAS. The total Pb intake of the Canarian population is 72.8 microg/day, 29.12% (for a person of 70 kg body weight) of the provisional tolerable weekly intake limit of 25 microg/kg fixed by the FAO/WHO. The island that presents the highest lead intake is La Gomera, followed by Lanzarote, Tenerife, and Gran Canaria islands. These four islands present a lead dietary intake over the mean Pb intake for the whole archipelago. The islands with lower Pb intakes are La Palma and Fuerteventura, with intakes under 70 microg/day. These results have also been compared with the values found for other national and international communities.
对大多数人来说，饮食是接触痕量金属的主要途径，因此有关饮食摄入量的信息对于评估这些元素对人类健康的风险也很重要。本研究的目的是测定作者所在社区中消费最多的食品和饮料中的铅含量，以估算加那利群岛七个岛屿各自的每日铅摄入量。使用石墨炉原子吸收光谱法对420个样本进行了分析。加那利群岛居民的铅总摄入量为72.8微克/天，（对于一名体重70千克的人来说）占粮农组织/世界卫生组织设定的25微克/千克暂定每周耐受摄入量限值的29.12%。铅摄入量最高的岛屿是戈梅拉岛，其次是兰萨罗特岛、特内里费岛和大加那利岛。这四个岛屿的膳食铅摄入量高于整个群岛的平均铅摄入量。铅摄入量较低的岛屿是拉帕尔马岛和富埃特文图拉岛，摄入量低于70微克/天。这些结果还与其他国家和国际社区的数值进行了比较。
