The delta9-tetrahydrocannabinol (delta9-THC) content was identified and determined quantitatively using a Gas Chromatography Detector (Gas Chromatography-Electron Ion Detector) instrument in samples of illicit herbal cannabis. Law enforcement authorities sent the samples to the Department of Forensic Medicine and Toxicology, University of Athens, for toxicological analysis. The concentrations o...

Laboratories that perform toxicology screens are challenged by the requirement to look for large numbers of target compounds in samples that contain complex matrix interferences. GC/MS methods are widely used and accepted for this analysis. Full-scan EI methods offer many advantages for broad-range screening, such as unlimited numbers of targets, full-spectrum identity confirmation, and library...

This study describes a method for off-line coupling of thin-layer chromatography (TLC) with electron impact ionization (El)-mass spectrometry for routine determination of pesticides in toxicology and forensic medicine. Six TLC solvent systems are described for 151 different pesticides, and 8-peak mass-spectra generated from full El mass spectra are listed.

Benzodiazepines are frequently encountered in forensic toxicology. A literature search was conducted to find a simple method using electron impact-gas chromatography-mass spectrometry (EI-GC-MS) to examine whole blood specimens for the most commonly encountered benzodiazepines in the United States. A recently published method was identified in the literature search and used as a starting point ...

OBJECTIVE Benzodiazepines are frequently screened drugs in emergency toxicology, drugs of abuse testing, and in forensic cases. As the variations of benzodiazepines concentrations in biological samples during bleeding, postmortem changes, and redistribution could be biasing forensic medicine examinations, hence selecting a suitable sample and a validated accurate method is essential for the qua...

Purpose: to investigate the effects of phosphide on some human biological systems in order to find a way to control it and facilitate the prevention and treatment of its poisoning. Materials and Methods: In this study, 67 files of autopsy description, forensic pathology results and forensic toxicology were studied as nominal qualitative variables in terms of each type of histological changes in...
