Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants.
The traditional definition of toxicology is "the science of poisons." As our understanding of how various agents can cause harm to humans and other organisms, a more descriptive definition of toxicology is "the study of the adverse effects of chemicals or physical agents on living organisms".
There are various types of toxicology as outlined below:
Analytical toxicology. Applied toxicology. Clinical toxicology. Veterinary toxicology. Forensic toxicology. Environment toxicology. Industrial toxicology.
