The objective of the present study is to determine the differences between the mineral content of various organs of and , the two most abundant edible snail species in Montenegro. The bioaccumulation of 12 examined elements (zinc, manganese, copper, aluminum, cadmium, lead, nickel, iron, chromium, lithium, selenium and mercury) was determined in the hepatopancreas, albumen gland, digestive tract, reproductive system, mantle, foot and shell from three sampling sites (Biogradska Gora, Nikšić and Malesija). The examined populations of and showed a significant difference in their lithium and selenium contents. The levels of the most examined metals (Zn, Mn, Cu, Al, Cd, Pb, Se and Hg) varied significantly among organs. The digestive tract and hepatopancreas tend to bioaccumulate selenium and cadmium. The general mean concentration of cadmium in the examined snail tissues exceeded the maximum allowable level at the Biogradska Gora and Malesija sites. Therefore, the use of the Montenegrin edible snails collected from the wilderness for human consumption seems to be limited by their higher bioaccumulation capacity for toxic elements such as cadmium.
本研究的目的是确定黑山两种最常见的可食用蜗牛物种—— 和 的各器官矿物质含量之间的差异。在来自三个采样地点（比奥格拉德山、尼克希奇和马莱西贾）的样本中，测定了肝胰腺、蛋白腺、消化道、生殖系统、外套膜、足部和外壳中12种被检测元素（锌、锰、铜、铝、镉、铅、镍、铁、铬、锂、硒和汞）的生物累积情况。被检测的 和 种群在锂和硒含量上存在显著差异。大多数被检测金属（锌、锰、铜、铝、镉、铅、硒和汞）的含量在各器官间有显著差异。消化道和肝胰腺倾向于生物累积硒和镉。在比奥格拉德山和马莱西贾采样点，被检测蜗牛组织中镉的总体平均浓度超过了最大允许水平。因此，食用从野外采集的黑山可食用蜗牛似乎因它们对镉等有毒元素较高的生物累积能力而受到限制。
