A trace element, also called minor element, is a chemical element whose concentration (or other measure of amount) is very low (a "trace amount"). They are classified into two groups: essential and non-essential. Essential trace elements are needed for many physiological and biochemical processes in both plants and animals. Not only do trace elements play a role in biological processes but they also serve as catalysts to engage in oxidation and reduction mechanisms. Web9 dec. 2024 · In geochemistry, major elements are usually considered to be above 1%, minor elements are between 0.1% and 1%, and trace elements are below that and usually measured in ppm. Note that this applies per sample. For instance, silicon would be the only major element in sand, whereas it would be a trace element in pure limestone.
