Selenium (Se) status of Hungarian rock-soil systems has been poorly investigated. The goal of this study was to get general information on the main features of Se geochemistry, and to have a brief look into the human Se status in Hungary, developing an appropriate method for a forthcoming systematic regional investigation. A multistage program was applied: 1. stream sediment sampling; 2. investigation of rock-soil profiles typical in Hungary; and 3. extraction of mobile Se fractions from soils. Human serum samples from apparently healthy blood donors residing in both urban and rural areas were collected from three districts in Hungary. It was concluded that Hungarian rock-soil systems, especially the acid igneous rocks and the widely distributed young sediments (loess and sand formations) with most of the agricultural activity, are low in Se, and the mean serum Se level of the blood samples were also low.
匈牙利岩石-土壤系统中的硒（Se）状况尚未得到充分研究。本研究的目的是获取有关硒地球化学主要特征的一般信息，并简要了解匈牙利人的硒状况，为即将开展的系统区域调查开发一种合适的方法。采用了一个多阶段计划：1. 河流沉积物采样；2. 研究匈牙利典型的岩石-土壤剖面；3. 从土壤中提取可移动硒组分。从匈牙利三个地区采集了居住在城乡的明显健康献血者的人血清样本。得出的结论是，匈牙利的岩石-土壤系统，特别是酸性火成岩和大部分农业活动所在的广泛分布的年轻沉积物（黄土和砂层），硒含量较低，血样的平均血清硒水平也较低。
