In forensic toxicology, which statement is not accurate?

• A. The chemist identifies the substance.
• B. The toxicologist determines the effects of the substance.
• C. The chemist also determines the effects of the substance.
• D. Both roles involve identifying substances.

Answer: (C)

In forensic toxicology, the work is split between identifying what is present and interpreting what it means for harm. The chemist focuses on the analytical process: selecting methods, running tests, and determining the exact chemical identity and concentration of substances in a sample. The toxicologist uses knowledge of toxicology, physiology, and pharmacology to interpret what those findings mean clinically or for the case—such as whether the substance could have caused observed symptoms or death, and in what exposure scenario. The statement that the chemist also determines the effects is not accurate because evaluating toxic effects requires toxicology expertise and interpretation of dose, mechanism, and clinical relevance. That toxicologist role is the one dedicated to assessing effects and their significance to the case, while the chemist provides the identity and measurement data. The other statements align with the usual division of labor: identifying the substance is a chemist’s primary task, and determining the effects is the toxicologist’s.
