[Selenium content in wheat and rye flow from Russia, cis nations and Baltic countries]

Selenium concentrations in wheat and rhy flour of Russia and CSC vary from 46 to 577 mg/kg and from 6 to 87 mg/kg correspondingly. The highest wheat flour selenium--300-600 mg/kg--is typical to wheat, imported from USA and Canada. Low values of selenium wheat flour (34-64 mg/kg) and of selenium rhy flour (5-20 mg/kg) from Kaliningrad, Novgorod, Pskov, Leningrad regions, Altay, Byelorussia and Baltic countries show the possibility of low selenium consumption by the population of these regions. Low selenium is demonstrated for wheat flour imported to Kirghizia - 81 +/- 31 mg/kg and produced in north-western part of Ukrain: Volinsk, Sumi, Kiev regions--64-78 mg Se/kg. Sakhalin and selenium-deficient Buryatia utilize predominently imported wheat flour with high selenium content - 250-260 mg/kg. Native grain with relatively high selenium is found in Kurgan, Orenburg, Lipetsk, Tambov regions, Tataria and Uzbekistan - 160-185 mg/kg.
