tracemetal

Trace metal refers to a chemical element that is present in extremely small quantities, typically measured in parts per million or parts per billion. Despite their low concentrations, trace metals can play crucial roles in a variety of biological, geological, and chemical processes. In biology, many trace metals are essential micronutrients for living organisms, participating in enzyme functions, oxygen transport, and metabolic pathways. Examples include iron, zinc, copper, and manganese. Deficiencies or excesses of these elements can lead to significant health issues.

Geologically, trace metals are found in minerals and rocks, and their distribution can provide clues about the Earth's formation and evolution. They are also important in environmental science, as their presence in soil, water, and air can indicate pollution levels or natural background concentrations. Certain trace metals, such as lead, mercury, and cadmium, are known for their toxicity even at low levels and are considered environmental contaminants. Their study is vital for understanding and mitigating environmental damage. The analysis of trace metals often requires specialized techniques due to the minute quantities involved.
