Abstract

In this article, the duplication portion technique was used to determine the daily intakes of selenium and ten other elements in the 24-h total diets collected in the typical Kashin-Beck endemic areas, i.e., Shanxi Province and Inner Mongolia Autonomous of China. The contents of Ca, Mg, Cu, Fe, Zn, Mn, Al, Sr, Ba, and P in freeze-dried samples were determined by ICP-AES. Se was determined by differential pulse catalytic polarography.

The average Se contents in total diets of Shanxi Kashin-Beck endemic and nonendemic areas were 0.009 and 0.021 μg/g (dry weight), respectively (P<0.001), corresponding to the daily intakes for Se of 4.6 and 10.5 μg. After the Se-supplemented fertilizer was applied (225 g of Na2SeO3/ha), the average Se content in total diets of Kashin-Beck disease area was increased to 0.0336 μg/g, which corresponded to the average daily intake for Se of 16.8 μg.

In Inner Mongolia Kashin-Beck endemic and nonendemic areas, the average Se contents in total diets were 0.006 and 0.017 μg/g, respectively (p<0.001), corresponding to the average daily intakes for Se of 3 and 8.5μg. The contents of other ten elements in total diets in endemic and nonendemic areas were reported and compared.
