Abstract:
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.
