Forensic analysis can detect paint thinner ingestion by identifying specific components in gastric contents and body tissues. Toluene, ethyl acetate, and isobutanol are key indicators in stomach samples, while only toluene appears in blood and tissues.

Area of Science:

  • Forensic Toxicology
  • Analytical Chemistry

Background:

  • Paint thinner ingestion is a critical forensic toxicology concern.
  • Accurate identification of ingested substances is vital for legal and medical investigations.

Purpose of the Study:

  • To develop and validate a method for detecting paint thinner ingestion.
  • To determine the distribution of paint thinner components in biological samples.

Main Methods:

  • Experimental administration of a standard paint thinner solution (toluene, ethyl acetate, isobutanol) to rats.
  • Analysis of gastric contents, blood, and tissues using gas chromatography with salting-out and headspace techniques.

Main Results:

  • Three thinner components (toluene, ethyl acetate, isobutanol) and ethanol (a metabolite of ethyl acetate) were detected in gastric contents.

  • Toluene was identified in blood and other tissues.
  • Ethyl acetate and isobutanol were not detected in blood or tissues.

    • Conclusions:

    • Paint thinner ingestion can be confirmed by detecting ethyl acetate and isobutanol alongside toluene in the stomach.
    • Toluene is the primary detectable component in blood and tissues following ingestion.
