Trace analysis is a critical component in modern forensic investigation in both Brazil and the United States. In Brazil, it plays an essential role in criminal investigations conducted by the Federal Police (Polícia Federal) and state police departments. The term is widely used in academic institutions and scientific laboratories. In the U.S., trace analysis is fundamental to FBI investigations and is commonly referenced in legal proceedings and crime scene investigations. The methodology is internationally standardized, making it relevant in both Portuguese and English-speaking legal and scientific communities.
