Toxicological Analysis Section

General information

The Laboratory employs 11 persons: 7 chemists, a pharmacist, a biologist and an environmental engineer; 6 employees have doctorate degrees; 6 are experts.

Head of Section:

Wojciech Lechowicz, PhD

The laboratory tests biological material (body fluids, internal organs, hair) and non-biological material in order to demonstrate or exclude the presence of and quantitate groups of substances such as:

  • narcotic drugs and psychotropic substances,
  • substances acting similarly to alcohol,
  • active ingredients of pharmacological preparations,
  • pesticides,
  • volatile organic compounds,
  • many other organic poisons of plant or synthetic origin.

The scope of expert opinions depends on the questions contained in the court decisions. When interpreting results, the circumstances of the incident are taken into account.


Research conducted in the Laboratory is connected to expert witnessing activities, and its primary objective is to solve new problems that are emerging in this field. Currently, a 4-year EU project is being implemented concerning estimation of the number of drivers who drive vehicles under the influence of alcohol and/or drugs acting similarly to alcohol.
Experts provide training in toxicological analysis for medical doctors, laboratory diagnosticians and lawyers under a program of development and specialisation courses organised by the Center for Postgraduate Medical Education and the Center for Forensic Science Education.
The laboratory participates in competence tests organised by the German Society of Forensic Toxicology and Chemistry GTFCH.


The laboratory is equipped with the following analytical equipment:

  • 4 optical microscopes,
  • 96-well spectrophotometric reader for the ELISA method,
  • 3 liquid chromatographs with PDA detectors,
  • 2 gas chromatographs with flame ionisation detectors,
  • 3 gas chromatographs with mass spectrometer detectors,
  • 2 liquid chromatographs with mass spectrometer detectors,
  • a device to enrich analytes.
