The Estimation of Dissolved Oxygen in Fresh Underground Water

[摘要] It is expected (Vernadsky: La Géochimie, p. 50) that fresh underground water dissolves little or no free oxygen in it, as the rain water which is saturated with air loses the dissolved oxygen in soil by the actions of soil materials and organisms. The author could ascertain, on analyzing some water in the Artesian well, that the oxygen content was low (8.9%-1.2% of the saturation). The samples of water were got from several wells in the suburb of Yokohama and in the compound of the Aeronautical Institute in Tokgo.
