The purpose of this study was to determine the daily dietary intake of uranium (U) by the general population of Catalonia, Spain. Uranium concentrations were measured in foods widely consumed by the population living in that autonomous community. Food samples were randomly acquired in 12 representative cities of Catalonia. The dietary intake of U was estimated for various age-gender groups: children, adolescents, adults, and seniors. Fish and seafood was the food group showing the highest U concentrations (0.090 μg/g of fresh weight (fw)), followed by dairy products (0.044 μg/g fw). In contrast, the lowest U levels were found in oils and fats (0.003 μg/g fw), while in tubers and milk, U was not detected in any sample. The estimated dietary intake of U for a standard male adult of 70 kg body weight living in Catalonia was 15.48 μg/day. According to the age/gender of the population, the highest dietary intake of U corresponded to children (20.32 μg/day), while senior females was the subgroup with the lowest U intake (10.04 μg/day). Based on the tolerable daily intake established for U, the current dietary intake of this metal by the general population of Catalonia should not mean health risks for any of the different age/gender groups of consumers.
本研究旨在确定西班牙加泰罗尼亚地区普通人群的铀（U）日膳食摄入量。对在该自治区生活的人群广泛食用的食物中铀浓度进行了测量。在 12 个具有代表性的加泰罗尼亚城市中随机采集了食物样本。针对不同年龄-性别组，估算了 U 的膳食摄入量：儿童、青少年、成年人和老年人。鱼类和海鲜是 U 浓度最高的食物组（0.090μg/g 鲜重 (fw)），其次是奶制品（0.044μg/g fw）。相比之下，油和脂肪中 U 含量最低（0.003μg/g fw），而在块茎和牛奶中，未在任何样本中检测到 U。对于居住在加泰罗尼亚、体重为 70 公斤的标准成年男性，估算的 U 膳食摄入量为 15.48μg/天。根据人口的年龄/性别，U 的最高膳食摄入量与儿童（20.32μg/天）相对应，而女性老年人是 U 摄入量最低的亚组（10.04μg/天）。基于为 U 确定的可耐受日摄入量，加泰罗尼亚普通人群目前的这种金属膳食摄入量不应对任何不同年龄/性别组的消费者造成健康风险。
