摘　　要：目的通过测定泰安市肥城徐东区部分原粮及食用油中微量元素及重金属含量,进一步探讨该地区人群微量元素营养状况及重金属摄入情况。方法采用原子吸收分光光度法。结果通过与我国粮食营养元素值比较,该地粮油中微量元素和重金属含量相近,符合人体健康需求;与1993年所测值相比,K、Zn、Ca、Na含量较高,Ca尤其突出,而Mg、Mn的含量相近,重金属含量相对较低。讨论该地区粮油中微量元素含量与其他地区比较无差异,重金属的含量处于较低水平,不存在重金属污染问题。Objective： To investigate the microelement and heavy metal content of some crude grain and edible oil in Feicheng-xudong area of Taian city and to assess the microelement nutrition status and heavy metal intake of the inhabitants.Methods：The atomic absorption spectrophotometry was used.Results：The microelement and heavy metal content of grain and oil in this area were similar to recommended food nutrient element level and met the health requirement in China.Compared to the measured value in 1993,the content of potassium,zinc,calcium and natrium was higher,especially calcium while magnesium and manganese were not changed significantly,and the content of heavy metals was lower.Conclusion： The microelement content of grain and oil in this area is similar to other areas and heavy metal level is not high enough to induce pollution.
