Toxicology

Toxicology is the scientific discipline, situated at the intersection of biology, chemistry, and medicine, that studies the adverse effects of chemical, physical, or biological agents on living organisms and the ecosystem. This field involves identifying toxic substances, understanding their mechanisms of action, and determining the dose-response relationship, which establishes the level of exposure that causes harm. Toxicologists play a critical role in assessing the safety of drugs, food additives, and industrial chemicals, as well as in diagnosing and treating poisonings and developing regulations to protect public and environmental health.
