trace analysis

Trace analysis is a method used in various fields to study remnants or "traces" left behind from past events. In forensics, it involves examining tiny pieces of evidence, such as fibers or fingerprints, to uncover details about a crime scene. In environmental science, it may refer to analyzing trace chemicals or pollutants in soil or water to assess contamination. Overall, trace analysis is about carefully examining subtle signs to gain insights into what has happened, helping experts piece together stories or data from limited evidence.
