Trace Element Analysis is a scientific method used to detect and measure the presence of trace elements in various materials, such as soil, water, and biological samples. These elements, which include metals like lead, mercury, and arsenic, are present in very small amounts but can significantly impact health and the environment. This analysis is crucial in fields like environmental science, nutrition, and forensic science. Techniques such as mass spectrometry and inductively coupled plasma are commonly employed to ensure accurate measurements, helping researchers understand the role of these elements in ecosystems and human health.
