The concentrations of 13 elements (Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn) were determined in several samples of native (wild) naturally growing and cultivated blueberry fruits. The total metal contents after mineralization were analyzed by inductively coupled plasma optical emission spectrometry. Reliability of the procedure was checked by the analysis of the certified reference materials Mixed Polish Herbs (INGT-MPH-2) and Leaves of Poplar (NCS DC 73350). In the fruits collected in the forest (wild blueberries), higher contents of Ca, Na, and Mg as well as Mn and Zn were observed. Similar levels of Cu, Cr, Fe, and Ni were detected in both wild-growing and cultivated plants. The significantly higher content of Fe and Cd in cultivated blueberries was connected with the content of these metals in soil samples collected from the same places. The metal extraction efficiency by hot water varied widely for the different blueberries (wild or cultivated) as well as their form (fresh or dried).
测定了几种野生（天然）和种植蓝莓果实样本中 13 种元素（Al、Ca、Cd、Cr、Cu、Fe、K、Mg、Mn、Na、Ni、Pb 和 Zn）的浓度。经矿化后，采用电感耦合等离子体光学发射光谱法对总金属含量进行分析。通过分析认证参考物质混合波兰草药（INGT-MPH-2）和杨树叶片（NCS DC 73350）来检查程序的可靠性。在森林中采集的（野生蓝莓）果实中，观察到 Ca、Na 和 Mg 以及 Mn 和 Zn 的含量较高。在野生和种植植物中，Cu、Cr、Fe 和 Ni 的含量相似。种植蓝莓中 Fe 和 Cd 的含量明显较高，这与从同一地点采集的土壤样本中这些金属的含量有关。不同蓝莓（野生或种植）及其形式（新鲜或干燥）热水提取金属的效率差异很大。
