Area of Science:

  • Forensic Toxicology
  • Environmental Health

Background:

  • Organophosphate pesticides, such as azinphos-ethyl, pose significant public health risks.
  • Accurate toxicological analysis is crucial for determining cause of death and intoxication levels in forensic investigations.

Purpose of the Study:

  • To report azinphos-ethyl concentrations in biological samples from deceased individuals.
  • To investigate the correlation between azinphos-ethyl levels and intoxication severity.
  • To present rapid analytical methods for azinphos-ethyl detection in human fluids.

Main Methods:

  • Analysis of azinphos-ethyl concentrations in blood, urine, and gastric lavage.
  • Categorization of cases into less serious, more serious, and fatal intoxication levels.
  • Development and application of fast methods for azinphos-ethyl identification and quantification.

Main Results:

  • Azinphos-ethyl was detected in all cases, confirming pesticide ingestion.
  • No definitive blood azinphos-ethyl levels could be established to accurately determine intoxication degree or lethal dose.
  • Rapid analytical techniques were successfully applied for azinphos-ethyl detection.

Conclusions:

  • Establishing precise toxicological thresholds for azinphos-ethyl in human samples remains challenging.
  • Rapid analytical methods are vital for timely forensic toxicological assessments.
  • Further research is needed to correlate pesticide exposure with clinical outcomes.
