Influence of Deuterium-Depleted Water on the Isotope D/H Composition of Liver Tissue and Morphological Development of Rats at Different Periods of Ontogenesis

Background: This study aimed to evaluate the reaction of organism of laboratory animals on deuterium-depleted drinking diet. To assess the cell energy metabolism, the effect of a liquid medium with different deuterium contents on isolated liver mitochondria of random bred rats and Wistar rats was studied. Methods: This experimental study on the effect of deuterium-depleted drinking water (DDW) ...

Isotope-hydrochemistry of Arnave karstic spring and Shirin dareh dam reservoir, North Khorasan

Surface and groundwater resources such as Arnaveh karstic spring and Shirin Dareh reservoir are the main sources of drinking water and agricultural activity in the North Khorasan province, northeast of Iran. The main agents of this study are to evaluate the origin, hydrochemical and isotope characteristics of water resources and also suitability of the Shirin dareh reservoir water for drinking ...

The oxygen isotope composition of dissolved anthropogenic phosphates: a new tool for eutrophication research?

High-precision oxygen isotope analyses were carried out on dissolved phosphate extracted from discharge waters from three wastewater treatment plants (WTP) located in western France, as well as on the different phosphate-based fertilizers applied by farmers in the same region. Measured delta(18)O values of phosphate from chemical fertilizers range from 19.6 to 23.1 per thousand, while those of ...

Mean Oxygen-isotope Composition of the Protosolar Molecular Cloud Silicate Dust

Oxygen-isotope composition of the solar wind returned by GENESIS indicates that the Sun is 16 O-rich (Δ 17 O SMOW = −26±6‰) [1], supporting one of predictions of the CO self-shielding models [2−4]. The self-shielding models [3,4] assume that both the solids and gas were similarly 16 O-rich (Δ 17 O ~ −25‰), and solids subsequently evolved towards the terrestrial value as a result of CO self-shie...

Hydrogen and oxygen isotope ratios in body water and hair: modeling isotope dynamics in nonhuman primates.

The stable isotopic composition of drinking water, diet, and atmospheric oxygen influence the isotopic composition of body water ((2)H/(1)H, (18)O/(16)O expressed as δ(2) H and δ(18)O). In turn, body water influences the isotopic composition of organic matter in tissues, such as hair and teeth, which are often used to reconstruct historical dietary and movement patterns of animals and humans. H...
