Human exposure to contaminated food is a general health concern worldwide; it is necessary to evaluate food safety with respect to contaminants present in the edible parts of major food crops. This study evaluated the concentrations of 17 trace elements (As, Be, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Se, Sn, Tl, V, and Zn) from 51 potato plantations in the Campania region, inside the area known as the "Triangle of Death," with inductively coupled plasma mass spectrometry analysis. Results confirm that the potatoes collected from the suburban area of Naples contained concentrations of trace elements below the safe limits prescribed by the Food and Agriculture Organization of the United Nations and the World Health Organization. The concentrations of elements were similar to those reported for potatoes grown in other countries. Monitoring the content of toxic and potentially toxic elements is one of the most important aspects of food quality assurance. The environmental persistence of metals may result in the accumulation of significant levels of these contaminants in plants. They are absorbed to different extents, depending on their source, soil and climatic factors, plant genotype, and agrotechnical conditions, thereby entering the food chain and representing a risk to human health.
人类接触受污染食品是全球普遍关注的健康问题；有必要针对主要粮食作物可食用部分中存在的污染物来评估食品安全。本研究采用电感耦合等离子体质谱分析法，对“死亡三角”区域内坎帕尼亚地区51个马铃薯种植园中的17种微量元素（砷、铍、镉、钴、铬、铜、铁、锰、钼、镍、铅、锑、硒、锡、铊、钒和锌）浓度进行了评估。结果证实，从那不勒斯郊区采集的马铃薯中微量元素浓度低于联合国粮食及农业组织和世界卫生组织规定的安全限值。这些元素的浓度与其他国家报道的马铃薯中的浓度相似。监测有毒和潜在有毒元素的含量是食品质量保证最重要的方面之一。金属在环境中的持久性可能导致这些污染物在植物中大量积累。它们的吸收程度各不相同，这取决于其来源、土壤和气候因素、植物基因型以及农业技术条件，从而进入食物链并对人类健康构成风险。
