Deuterium in Water – Essential for Life
Posted by keelynet on November 20, 2010
Russian researchers developed an express-technique for testing toxicity of water with high and low deuterium concentration and discovered an interesting fact – deuterium is a crucial element for normal functioning of a living cell.
Natural water normally contains two hydrogen isotopes: protium and deuterium, which concentration is about 156 parts per million (ppm). Light water (with low deuterium concentration) is believed to have positive effects on human health.
Heavy water is toxic – it prevents cells from normal division, if its concentration in an organism is about 25-50%. Scientists suggested using a test organism, an infusorium Spirostomum ambiguum, which is very convenient to work with due to its size – about 1 mm.
Experiments showed that deuterium concentration of 50-125 ppm had no effect on infusoria lifespan, but organisms had quickly died in water with lower or higher deuterium content.
Researchers believe that some certain deuterium content is crucial for normal functioning of a living cell. – Full Article Source
