[Efficiency of iodine and selenium enriched drinking water use to prevent deficiency states in population of the Altai Territory].

Numerous epidemiological studies suggest that there is an association between the quality of drinking water and human health. The Altai Territory is a biogeochemical province characterized by deficiency of many trace elements, including iodine and selenium. The measures implemented in organized children's collectives to prevent iodine- and selenium-enriched deficiency states, by providing the supply of drinking waters enriched with iodine and selenium, have demonstrated a more marked effect in preventing iodine deficiency states than that of the water corrected only for the iodine composition.

[A cause of the abnormal properties of melt water].

The physicochemical properties and crystal structure of melt water were studied. Melt water was found to be in the active metastable state with the non-equilibrium concentration of hydrogen and hydroxyl. The biological activity of such water is accounted for by its small sizes of supramolecular complexes.

[Analytical control of organic impurities in the drinking and bottled water after its contact with a pack and filters made from polymer materials].

The paper provides the results of gas chromatographic analysis of organic impurities in the drinking water after its contact with various packs and filters made from polymer materials. Vapor-phase analysis in combination with selective gas chromatographic detectors was used to determine volatile substances and liquid extraction in combination with chromatographic mass-spectrometry was employed to identify high-boiling compounds. The release sources of toxic compounds from materials to water, the taste and odor of which is affected by them were studied.
