Daily intakes of iron (Fe), copper (Cu), zinc (Zn) and manganese (Mn) from whole-day food rations composed by dieticians and collected in hospital canteens in Krakow, Lodz, Olsztyn and Poznan, Poland, in the winters of 1993/94, 1995 and 1996, were determined by atomic absorption spectrometry. The average intake of Fe, 14 mg x day(-1), was satisfactory for both women and men; 13 mg Zn fulfilled the safe level for women (taken as the recommended minimum level to meet the needs of 97.5% of the population) but it was too low for men, and 1.3 mg Cu corresponded to 65-72% of the safe level set for this microelement in Poland. There is no recommended level set in Poland for Mn, but compared with recommended levels in Germany and the USA, the determined daily Mn intake equal to 3.7 mg should be sufficient. Statistical analysis confirmed higher amounts of Zn and Mn in diets collected in Krakow, higher Cu content in diets from 1996, and lower Mn content in food collected in 1995.
1993/94年、1995年和1996年冬季，在波兰克拉科夫、罗兹、奥尔什丁和波兹南的医院食堂收集了由营养师制定的全天食物定量，采用原子吸收光谱法测定了其中铁（Fe）、铜（Cu）、锌（Zn）和锰（Mn）的每日摄入量。铁的平均摄入量为14毫克/天，对女性和男性来说都较为充足；锌的摄入量为13毫克，达到了女性的安全水平（作为满足97.5%人口需求的推荐最低水平），但对男性来说过低，而铜的摄入量为1.3毫克，相当于波兰为该微量元素设定的安全水平的65 - 72%。波兰没有为锰设定推荐水平，但与德国和美国的推荐水平相比，测定的每日锰摄入量为3.7毫克应该是足够的。统计分析证实，克拉科夫收集的饮食中锌和锰的含量较高，1996年收集的饮食中铜含量较高，1995年收集的食物中锰含量较低。
