Selenium Status of Omsk Region
The human selenium status in 32 districts of Omsk region was determined, serum selenium being in the range 73-116 µg/L. An indirect correlation was found between serum selenium concentrations and whole mortality, malignаncy from lung cancer, ovarian cancer and rectal cancer. Significant differences in selenium accumulation coefficient in plants were shown to depend on the type of soil. Methods of the human selenium status optimization are discussed.
