halottkémiás

Halottkémiás, often translated as thanatochemistry, is a sub-discipline within forensic science that focuses on the chemical changes that occur in a body after death. This field investigates the decomposition processes, the identification of chemical substances present in tissues and bodily fluids, and their potential role in determining the cause or circumstances of death. It encompasses the study of endogenous chemical reactions within the body as well as exogenous influences.

Key areas within halottkémiás include the analysis of putrefaction, rigor mortis, and algor mortis, all of which involve biochemical alterations. Researchers in this field examine the breakdown of proteins, carbohydrates, and lipids, as well as the changes in pH and the production of various gases. They also study the distribution and persistence of drugs, poisons, and other xenobiotics within the decomposing body, which can be crucial for toxicological investigations.

The methodologies employed in halottkémiás often involve sophisticated analytical techniques such as gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and various spectroscopic methods. These techniques allow for the precise identification and quantification of chemical compounds. The data generated from halottkémiás analyses can provide valuable insights for forensic pathologists, medical examiners, and law enforcement in reconstructing events surrounding a death and establishing a timeline of decomposition.
