某些对人体有益的矿物元素为维持人体正常生理功能所必需,如果摄入量不足或比例不当于健康不利,甚至引起病理变化。而对人体有害的元素则应在国家食品卫生法规定的容许标准之内。我们对60种潜艇远航食品中10种矿物元素的含量,用日立180-80型原子吸收光谱仪火焰法测定K、Na、Ca、Mg、Fe、Cu、Zn、Mn,用无火焰法测定Pb、Cd的含量,由下表结果表明对人体有益的前八种元素,在绝大多数食品中的含量都是丰富或比较丰富 Certain mineral elements that are beneficial to the human body are necessary for the maintenance of the normal physiological function of the human body, and even lead to pathological changes if the intake is inadequate or the proportion is improperly detrimental to health. The harmful elements of the human body should be within the allowable standard set by the National Food Sanitation Law. We measured K, Na, Ca, Mg, Fe, Cu, Zn, Mn by flame method of Hitachi 180-80 atomic absorption spectrometer for the content of 10 kinds of mineral elements in 60 kinds of submarine voyage food, Cd content, the following table results show that the first eight elements beneficial to humans, in most of the food content is rich or more abundant
