Trace metal stable isotope biogeochemistry is the study of the distribution and relative abundances of trace metal isotopes in order to better understand the biological, geological, and chemical processes occurring in an environment. Trace metals are elements such as iron, magnesium, copper, and zinc that occur at low levels in the environment. Trace metals are critically important in biology and are involved in many processes that allow organisms to grow and gener… SpletStable Isotopes Supplier Serving the medical, scientific research and nuclear communities with Stable Isotopes for over 30 years, Trace Sciences International has been the leader in the sale and distribution of Isotopes.
