The aim of this study was to determine the levels of iron (Fe), manganese (Mn), chromium (Cr), copper (Cu), zinc (Zn), mercury (Hg), cadmium (Cd) and lead (Pb) in several types of honey purchased from the local consumer markets in Central Italy by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Lead and Cd were also determined by Atomic Absorption Spectrometry with graphite tube atomization (AAS-GTA). The degree of humidity, sugar content, pH, free acidity, combined acidity (lactones) and total acidity were also measured. These elements were found to be present in honeys in various proportions depending upon (1) area foraged by bees, (2) flower type visited for the collection of nectar, and (3) quality of water in the vicinity of the hive. The honeys consumed in Italy were of good quality, but not completely free of heavy metal contamination. Compared with established recommended daily intakes, heavy metals or trace element concentrations in samples investigated, however, do not pose any serious concern to human health.
本研究旨在通过电感耦合等离子体质谱法（ICP-MS）测定从意大利中部当地消费市场购买的几种蜂蜜中的铁（Fe）、锰（Mn）、铬（Cr）、铜（Cu）、锌（Zn）、汞（Hg）、镉（Cd）和铅（Pb）的水平。铅和镉也通过石墨管原子化原子吸收光谱法（AAS-GTA）测定。还测量了湿度、糖含量、pH 值、游离酸度、总酸度（内酯）和总酸度。这些元素的存在比例取决于（1）蜜蜂采集的区域，（2）蜜蜂采集花蜜所访问的花的类型，以及（3）蜂巢附近水的质量。意大利消费的蜂蜜质量很好，但并非完全没有重金属污染。然而，与既定的推荐日摄入量相比，在所研究的样本中，重金属或微量元素的浓度对人类健康没有任何严重影响。
