Forensic Palynology deals with the study of pollen and other palynomorphs, contributing to the clarification and resolution of judicial cases, mostly of a criminal nature. Palynomorphs are microscopic structures that easily adhere to various surfaces, of natural, artificial or even human origin, without being noticed.
