Toxicologic pathology is a medical discipline that applies the professional practice of pathology—the study of diseases—to toxicology—the study of the effects of chemicals and other agents on humans, animals, and the environment. Toxicologic pathology professionals work in academic institutions, government, the pharmaceutical and chemical industry, contract research organizations or as consultants, and utilize traditional clinical or anatomic pathology endpoints, as well as contemporary advances in molecular and cellular biology. They are dedicated to the integration of toxicologic pathology into hazard identification, risk assessment, and risk communication regarding human, animal, and environmental exposure to potentiallytoxic substances.
