Cereal industry and its derived products have a big economic and social importance worldwide. Therefore, as wheat flour is a commodity for all bread and bakery industry, it is safety is of high nutrition and toxicological interest. In this investigation we intend to study and determine the content of twelve metals in 50 samples of wheat flour coming from a wheat flour industry. Macro elements sodium, potassium magnesium and calcium, micro elements manganese, iron, copper, zinc, chrome and nickel as well as toxic trace elements cadmium and lead have been analysed. The estimated diary intake of each metal and their contribution in percentage terms to the RDI (macro and micro elements) and to the PTWI (toxic elements) has been determined. Contribution of Cd and Pb to the PTWI was very low, a fact that shows safety in this wheat flour concerning toxic metals.
谷物产业及其衍生产品在全球具有重大的经济和社会意义。因此，由于小麦粉是所有面包和烘焙行业的商品，其安全性具有很高的营养和毒理学研究价值。在本研究中，我们打算对来自一家小麦粉厂的50个小麦粉样本中的12种金属含量进行研究和测定。分析了常量元素钠、钾、镁和钙，微量元素锰、铁、铜、锌、铬和镍，以及有毒微量元素镉和铅。已确定了每种金属的估计每日摄入量及其对RDI（常量和微量元素）和PTWI（有毒元素）的百分比贡献。镉和铅对PTWI的贡献非常低，这一事实表明该小麦粉在有毒金属方面是安全的。
