Forensic Toxicologist

Technologists & Technicians

If you are fascinated by the effects chemicals can have on the human body, this may be the career for you. Forensic toxicologists perform scientific tests on bodily fluids and tissue samples to identify any drugs or chemicals present in the body. Working in a lab, the forensic toxicologist performs tests on samples collected by forensic pathologists during an autopsy or by crime scene investigators. They use highly sophisticated instruments, chemical reagents and precise methodologies to determine the presence or absence of specific substances in the sample.

As part of a team investigating a crime, a forensic toxicologist will isolate and identify any substances in the body that may have contributed to the crime, such as:

  • Alcohol
  • Illegal or prescription drugs
  • Other chemicals
  • Poisons
  • Metals
  • Gases, such as carbon monoxide

The work requires patience and the ability to follow specific steps to achieve reliable results. The forensic toxicologist must document every step of the process and take care to follow rules regarding chain of custody for physical evidence.

The field of forensic toxicology has grown to include drug and alcohol testing for employers and traffic enforcement officials as well as testing animal samples for wildlife criminal investigators and testing for “date rape” drugs and performance-enhancing substances.

Forensic toxicologists also work on cases involving environmental contamination, to determine the impact of chemical spills on nearby populations.

Investigators rely on the forensic toxicologist to make reliable conclusions about the impact a specific amount of a specific substance would have on a specific individual. Often, this requires the professional to form an educated opinion based on science and experience.

If asked to testify in court, the forensic toxicologist must be prepared to justify that opinion and to explain complex methodologies in terms a jury can understand.
