Other human metabolism studies to determine the absorption patterns of nutrients have involved tracing a stable isotope of that mineral or element though the body. Iron (Using Iron-54, Iron-57 and Iron-58), Copper (Using Copper-63 and Copper-65), Zinc (Using Zinc-64, Zinc-67, Zinc-68 and Zinc-70), Magnesium (Using Magnesium-25 and Magnesium-26) and many others are used for this application. Other biomedical applications for American Elements' stable isotopes, include using Nickel-58, Nickel-60, Nickel-61 and Nickel-64 to study nitrogen absorption in the blood, Copper-63 and Copper-65 to study gastro-intestinal disorders, Molybdenum-94, Molybdenum-96 and Molybdenum-97 as a label on nutrients to trace metabolism of the labeled nutrient, Lithium-6 for research in kidney function, Vanadium-51 to study brain metabolism and Rubidium-85 and Rubidium-87 to study potassium absorption in the blood.
Isotopes are valuable in environmental and human exposure research. Chlorine-35 and Chlorine-37 are used to study environmental pollutants. Carbon-13 has application in the study of global warming and air pollution control. Lead-204, Lead-206 and Lead-207 can be used to measure human lead poisoning. Similarly, Chromium-53 and Chromium-54 can be used to study these effects with respect to Chromium.
Below is a table listing the Stable Isotopes available from American Elements. Please see a specific material for its ENSDF Citation, Abundance, Half-Life and other technical information, applications and properties.
