The Reaction between Oxygen and the Heavier Isotope of Hydrogen [PDF]
Nature, 1934 WE have made a preliminary survey of the principal respects in which the reaction of deuterium with oxygen differs from that of ordinary hydrogen. The deuterium was prepared by the nearly quantitative decomposition of 97 per cent deuterium oxide by repeated passage over pure iron.

Estimation of Surface and Groundwater Interaction by Stable Isotopic Techniques – A Case Study of Chengalpattu District, OMR Region [PDF]
Nature Environment and Pollution TechnologyIsotopes are atoms of an element having the same atomic number but different mass numbers. Isotopes in hydrology and water resources are used for identifying its occurrence, movement, residence times, recharge, and discharge process.

The Current Oxygen and Hydrogen Isotopic Status of Lake Baikal [PDF]
Water, 2021 This study revises the δ18O and δ2H status of Lake Baikal. The mean values of δ18O and δ2H varied from −15.9 to −15.5‰ and from −123.2 to 122.2‰, respectively, for the past 30 yr. The isotopic composition of the lake remained more ‘‘light” compared to the regional precipitation and rivers inflows.

Use of hydrogen and oxygen isotopes to understand evaporation from enclosed waterbodies
Journal of Environmental Engineering and Landscape Management, 2022 Getting information on evaporation is important for water resource protection and managing regional enclosed waterbodies. Some lake water samples were collected in May and June from a representative enclosed waterbody – the Pearl Lake, Suzhou, China ...
