differences of their roles in forensics

Forensic toxicologist

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

Forensic chemist

Forensic chemists analyze non-biological trace evidence found at crime scenes in order to identify unknown materials and match samples to known substances. They also analyze drugs/controlled substances taken from scenes and people in order to identify and sometimes quantify these materials. They run tests on samples collected by investigators. They use a variety of techniques, including microscopy, optical analysis (such as UV, infrared, X-ray), gas cinematography and other technologies. They carefully document their findings and write reports that are used to support criminal investigations. Forensic chemists may also testify to their findings in court.
