Influence of impurities on the content of [O-2] in water under microwave irradiation

A decrease of free O-2 content in distilled water and water salt solutions under microwave irradiation was observed. The reduced O-2 level persisted f or a long time (up to several hours) after the elimination of the, field. T he degree of the field influence on the O-2 content was determined by the p resence of ions in water. The effect was lacking when bidistillate or deion ized water were used in the experiments. The effect became evident after th e addition of CaCl2 (at concentrations below 1 mu M) to deionized water. Th e greatest decrease in [O-2] (up to 5%) was observed in the physiological s olution for vertebrates. The effects of a lesser degree were also observed in the solutions of CaCl2, MgCl2, NaCl, and other salts prepared on deioniz ed water. The data obtained showed that, for the manifestation (or arising) of the nonthermal effect of the field, which shows up in a partially irrev ersible decrease of O-2 content, the presence of some alkaline metal ions a nd, possibly, some other nonidentified impurities is necessary.
