  2. Trace metal - Wikipedia

    en.wikipedia.org/wiki/Trace_metal

    Trace metals are sometimes referred to as trace elements, although the latter includes minerals and is a broader category. See also Dietary mineral. Trace elements are required by the body for specific functions. Things such as vitamins, sports drinks, fresh fruits and vegetables are sources. Taken in excessive amounts, trace elements can cause ...

  3. Trace element - Wikipedia

    en.wikipedia.org/wiki/Trace_element

    A trace element is a chemical element of a minute quantity, a trace amount, especially used in referring to a micronutrient, [1] [2] but is also used to refer to minor elements in the composition of a rock, or other chemical substance. In nutrition, trace elements are classified into two groups: essential trace elements, and non-essential trace ...

  4. Trace metal stable isotope biogeochemistry - Wikipedia

    en.wikipedia.org/wiki/Trace_metal_stable_isotope...

    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 ...

  5. Mineral (nutrient) - Wikipedia

    en.wikipedia.org/wiki/Mineral_(nutrient)

    The generally accepted trace elements are iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine, selenium, [5] and bromine; [6] there is some evidence that there may be more. The four organogenic elements, namely carbon, hydrogen, oxygen, and nitrogen , that comprise roughly 96% of the human body by weight, [7] are usually not ...

  6. Biometal (biology) - Wikipedia

    en.wikipedia.org/wiki/Biometal_(biology)

    The metals copper, zinc, iron, and manganese are examples of metals that are essential for the normal functioning of most plants and the bodies of most animals, such as the human body. A few ( calcium , potassium , sodium ) are present in relatively larger amounts, whereas most others are trace metals , present in smaller but important amounts ...

  7. Ultratrace element - Wikipedia

    en.wikipedia.org/wiki/Ultratrace_element

    In biochemistry, an ultratrace element is a chemical element that normally comprises less than one microgram per gram of a given organism (i.e. less than 0.0001% by weight), but which plays a significant role in its metabolism.

  8. Compatibility (geochemistry) - Wikipedia

    en.wikipedia.org/wiki/Compatibility_(geochemistry)

    Compatibility is a term used by geochemists to describe how elements partition themselves in the solid and melt within Earth's mantle.In geochemistry, compatibility is a measure of how readily a particular trace element substitutes for a major element within a mineral.

  9. Manganese nodule - Wikipedia

    en.wikipedia.org/wiki/Manganese_nodule

    As the nodules are formed, trace elements including but not limited to nickel, cobalt, copper, and zinc are incorporated. [2] Trace metals composition is a product of three processes: uptake of parent material in surrounding soil, accumulation of the products of microbial iron or manganese-reducing bacteria, and complexation on the nodule's ...
