What does toxicology refer to?

Toxicology specifically refers to the study of poisons, toxins, drugs, and other substances and their effects on living organisms. This field examines the biochemical and physiological effects of these compounds, how they interact within the body, and the potential consequences of exposure. In forensic science, toxicology plays a crucial role in investigations, particularly in cases involving overdose, poisoning, or drug-related crimes, as it helps determine the presence and concentration of various substances in biological samples.

In contrast, other options focus on different aspects of forensic science. For instance, crime scene investigation techniques fall under the broader category of forensic analysis, while the analysis of forensic evidence in court involves legal proceedings and the presentation of findings rather than the study of substances themselves. Lastly, examining human behavior during a crime pertains more to psychology and behavioral analysis, rather than the chemical properties and impacts that toxicology addresses. Thus, the definition captured in the correct answer is essential for understanding how toxic substances are evaluated in a forensic context.
