Ten years study of selenium status in stream sediments, rocks, soils, water, cereal crops and food, as well as in the human tissues, has shown a Se deficiency in most parts of this country. Some of the results are presented and discussed, especially in connection with etiology of Balkan nephropathy and high incidence of urinary tract tumors in endemic areas.
Data on selenium (Se) deficiency in Yugoslavia are summarized. These data include the selenium contents of stream sediments, rocks, soils, cereal crops grown in these soils, and human serum and scalp hair from several towns and regions. Analyses of human tissues in Yugoslavia show very low Se concentrations in both endemic and nonendemic areas. In some regions, including those with endemic villages, selenium contents of grains and human serum and hair are extremely low, approaching those in the low-selenium zone in China. According to the biological function of selenium, a very low intake of selenium may be a fundamental underlying condition that would predispose persons to attack by other agents in the development of Balkan endemic nephropathy.
Data on selenium (Se) deficiency in Yugoslavia are presented. The results include Se content of soil, cereal crops, and garlic grown in these soils, and human serum and scalp hair from several towns and regions. All data indicate a serious Se deficiency: soil (n = 140), the mean value of 200 +/- 69.6 micrograms/kg Se; wheat, (58) mean = 20.5 +/- 12.4 micrograms/kg; corn, (79) mean = 13.7 +/- 13.6 micrograms/kg; and garlic, (66) mean = 13.7 +/- 17.1 micrograms/kg Se. Analyses of human tissue show a very low Se status of the Yugoslav population: serum, (n = 875) mean = 50.0 +/- 18.0 micrograms/L and scalp hair, (388) mean = 94 +/- 16 micrograms/kg Se. In some regions, Se contents of grain, garlic, and human serum and hair are approaching those in the low-Se belt in China. It is assumed that very low Se status of a human population could be a risk factor in the development of Balkan Endemic Nephropathy (BEN) and in a high incidence of urinary tract tumors (UTT) in endemic areas.
