Physical Description | Deuterium is an isotope of hydrogen but it is chemically identical. It is a colorless, odorless gas. It is easily ignited. Once ignited it burns with a pale blue, almost invisible flame. The vapors are lighter than air. It is flammable over a wide range of vapor/air concentrations. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is not toxic but is a simple asphyxiate by the displacement of oxygen in the air.

Non-Human Toxicity Excerpts

Replacement of more than one-third of the hydrogen by deuterium in body fluids of mammals or two-thirds of the hydrogen in higher green plants has catastrophic consequences for the organisms. At lower levels of deuterium in higher plants, growth is markedly slowed. In mice and rats low levels of deuterium result in sterility, and at higher concn neuromuscular disturbances, fine muscle tremors, and a tendency to convulsions can be noted. ... Impairment of kidney function, anemia, disturbed carbohydrate metabolism, central nervous system disturbances, and altered adrenal function /were found/ in deuterated mice. Hemoglobin and RBC count, serum glucose, and cholesterol all decrease in deuterated dogs. ... /However/ numerous green and blue-green algae have been grown in which > 99.5% of the...
