The objective of the study was to determine selenium status and its distribution in the organs of free living foxes from selenium deficient areas of north-western Poland. Samples of organs harvested from 40 foxes shot during the 2008-2009 hunting seasons served as experimental material. Selenium concentration in the organs was determined spectrofluorometrically. Selenium distribution in tissues depends largely on its dietary content. Our study indicated that concentrations of selenium in the examined organs followed the order: kidney>liver>spleen>lung>heart and kidneys were the organ with the highest retention of this element. Mean selenium concentration in fox kidneys was 0.60 +/- 0.15 microg/g wet weight. Several times less selenium on average was found in the liver (0.27 +/- 0.09 microg/g w.w.), lungs (0.17 +/- 0.06 microg/g w.w.), spleen (0.19 +/- 0.06 microg/g w.w.) and heart (0.13 +/- 0.05 microg/g w.w.). All the animals studied were deficient in selenium.
该研究的目的是确定来自波兰西北部缺硒地区的野生狐狸体内的硒状况及其在各器官中的分布。从2008 - 2009年狩猎季节射杀的40只狐狸身上采集的器官样本用作实验材料。用荧光分光光度法测定器官中的硒浓度。硒在组织中的分布很大程度上取决于其饮食含量。我们的研究表明，所检查器官中的硒浓度顺序为：肾脏>肝脏>脾脏>肺>心脏，肾脏是该元素保留量最高的器官。狐狸肾脏中的平均硒浓度为0.60±0.15微克/克湿重。在肝脏（0.27±0.09微克/克湿重）、肺（0.17±0.06微克/克湿重）、脾脏（0.19±0.06微克/克湿重）和心脏（0.13±0.05微克/克湿重）中平均发现的硒含量要少几倍。所有研究的动物都缺硒。
