What is the definition of toxicology?

The correct definition of toxicology is the study of poisons and their effects on living organisms. This field encompasses understanding how various substances can cause harmful effects, how they interact with biological systems, and the mechanisms underlying toxicity. Toxicologists assess exposure levels, evaluate health risks, and determine how poisons can affect human health as well as environmental safety.

This definition is foundational to the field, as it helps professionals understand the impacts of chemical substances in various contexts, including hazardous waste management, public health, and safety protocols. By focusing on the effects of poisons, toxicology provides critical insights necessary for emergency response and the assessment of hazardous materials encountered in various situations, such as those handled in HAZWOPER training.
