Selenium is an element essential to man. The main environmental pathway of Se-exposure for the general population is through food. As is true for all essential elements, not only deficient but also excessive exposure results in adverse health effects. Between these extremes there is a range of safe and adequate Se intakes. In 1980 the Italian National Research Council recommended 50-200 micrograms/day as an interval adequate to meet nutritional requirements, being at the same time below the threshold of toxic effects. Therefore the evaluation of dietary Se intake has become very important. The purpose of this work is the estimation of dietary intakes of Se using data on the amount and composition of an average Italian diet. Complete meals from a factory canteen were analyzed and calculations of weekly intake of Se carried out. Analyses were performed by means of Inductively-coupled Plasma Atomic Emission Spectrometry. The results obtained, related to the average and indicative food consumption of Italian people, showed that the daily intake is well within the recommended range.
硒是人体必需的一种元素。普通人群接触硒的主要环境途径是通过食物。与所有必需元素一样，不仅硒摄入不足，而且摄入过量都会对健康产生不良影响。在这两个极端之间存在一系列安全且充足的硒摄入量。1980年，意大利国家研究委员会建议每日摄入量为50 - 200微克，该区间既能满足营养需求，同时又低于毒性作用阈值。因此，评估膳食硒摄入量变得非常重要。这项工作的目的是利用意大利平均饮食的数量和成分数据来估算膳食硒摄入量。对一家工厂食堂的完整膳食进行了分析，并计算了每周的硒摄入量。分析采用电感耦合等离子体原子发射光谱法进行。根据意大利人的平均和指示性食物消费量得出的结果表明，每日摄入量完全在推荐范围内。
