Toxicology is the field that specifically studies substances that can impact the human body, including their effects, mechanisms of action, and the potential for harm. This discipline is crucial for understanding how various chemicals, drugs, and environmental agents can lead to adverse health effects. Toxicologists conduct research on the toxicity of these substances, determine safe exposure levels, and evaluate the potential for poisonings or overdoses. Their work is critical in fields such as medicine, pharmaceuticals, environmental science, and public safety.

The other fields listed do not center on this focus. Anthropometry deals with the measurement of the human body, particularly in relation to anthropology and ergonomics, which does not specifically address substances' effects on the body. Pathology is concerned with the study of diseases and their causes, effects, and processes, rather than the direct impact of substances. Sereology involves the study of blood serum and immune responses, but again, it is not focused on the effects of substances on the body as toxicology is. Therefore, toxicology is distinctly recognized as the appropriate choice in this context.
