Summary
This study details a fatal case of suicide due to acute MAPP gas intoxication. Forensic analysis confirmed lethal levels of methyl acetylene and propadiene (MAPP) in the deceased.
Area of Science:
- Forensic Toxicology
- Analytical Chemistry
Background:
- Methyl acetylene and propadiene (MAPP) gas is commonly used in industrial soldering and welding.
- Volatile compound analysis presents unique challenges in forensic investigations.
Observation:
- A 33-year-old male was found deceased with a MAPP gas cylinder and a plastic bag over his head.
- Toxicological screening revealed trace diphenhydramine and morphine, with MAPP components identified in blood and brain tissue.
Findings:
- Headspace gas chromatography (HS-GC) quantified MAPP components in femoral blood (59.6 mg/L) and brain (43.6 mg/kg).
- Acute MAPP intoxication was determined as the cause of death, with suicide as the manner of death.
Implications:
- This case highlights the potential for MAPP gas misuse and the importance of advanced analytical techniques for volatile compound detection.
- Understanding MAPP toxicity is crucial for forensic pathologists and toxicologists investigating similar cases.
