In times of widespread environmental pollution with heavy metals of anthropogenic origin and the increasing dynamics of this process, it is justified to collect as much data as possible on the concentration of metals in terrestial mammals from unpolluted areas. The purpose of this research was to present the concentration of essential (chromium, copper, iron, manganese, molybdenum, and zinc), probably essential (nickel, vanadium) and non-esential element (cadmium, lead, silver, strontium, and tin) in the liver, kidneys, muscles and brain of red fox (Vulpes vulpes) inhabiting north-western Poland. We revealed that the concentration of all metals, apart from Ni, was different between studied tissues. Sn and Mo have the highest affinity to the liver, whereas Ag, Sr, Cr had higher concentrations in the brain than in other organs. Various positive relationship between the concentrations of metals were observed in the tissues. Moreover, we noted negative correlations between Ag and Sn in the kidneys and brain, and between Cu and Ag in the liver. In our study the red fox was used as biomonitor for the assessment of exposure of carnivores to metals, in the generally unpolluted areas of Central Europe. Data presented in the report may be used as comparative values in similar ecotoxicological studies.
在广泛存在人为重金属污染和这一过程日益加剧的时代，有理由从未受污染的地区收集尽可能多的关于陆地哺乳动物体内金属浓度的数据。本研究的目的是展示在波兰西北部栖息的红狐（ Vulpes vulpes ）的肝脏、肾脏、肌肉和大脑中，必需元素（铬、铜、铁、锰、钼和锌）、可能必需元素（镍、钒）和非必需元素（镉、铅、银、锶和锡）的浓度。我们发现，除了 Ni 之外，所有金属在研究组织中的浓度都不同。Sn 和 Mo 对肝脏的亲和力最高，而 Ag、Sr、Cr 在大脑中的浓度高于其他器官。在组织中观察到金属浓度之间存在各种正相关关系。此外，我们还注意到肾脏和大脑中 Ag 和 Sn 之间以及肝脏中 Cu 和 Ag 之间存在负相关关系。在本研究中，红狐被用作评估食肉动物暴露于金属的生物监测器，在中欧一般未受污染的地区。报告中提供的数据可作为类似生态毒理学研究中的比较值。
