Crops intended for human nutrition and food production containing different essential trace elements, such as copper and zinc, could be contaminated by toxic metals like cadmium and lead. The interrelationship between micronutrients and contaminant trace elements in different cereals was investigated in North-western Italy, where both agricultural and industrial activities are present. Elemental concentrations in sampled cereals were assessed by inductively coupled plasma mass spectrometry (ICP-MS). Rice, oats and barley reached the highest median levels for Al, Cd and Pb content, while corn samples were less contaminated by toxic metals. Regarding essential elements highest median values of Cu and Zn were both found in barley, while Ni median content was higher in oats. Rice had the lowest median levels of essential elements. The correlation study between toxic and essential elements seemed to demonstrate fixed trends in analysed samples, corroborating the importance of a different diet to limit potential adverse effects caused by toxic elements.
用于人类营养和食品生产的含有不同必需微量元素（如铜和锌）的作物，可能会被镉和铅等有毒金属污染。在意大利西北部对不同谷物中微量营养素与污染物微量元素之间的相互关系进行了调查，该地区既有农业活动也有工业活动。通过电感耦合等离子体质谱法（ICP-MS）评估了采样谷物中的元素浓度。大米、燕麦和大麦的铝、镉和铅含量中位数达到最高水平，而玉米样本受有毒金属污染较少。关于必需元素，铜和锌的最高中位数含量均在大麦中发现，而镍的中位数含量在燕麦中较高。大米中必需元素的中位数水平最低。有毒元素与必需元素之间的相关性研究似乎表明了分析样本中的固定趋势，证实了不同饮食对于限制有毒元素可能造成的潜在不良影响的重要性。
