What is the study of poisons and their effects on living organisms called?

The study of poisons and their effects on living organisms is called toxicology. This field focuses on understanding how harmful substances interact with biological systems, including the mechanisms of toxicity, the effects of various doses, and the pathways through which these substances exert their effects on health. Toxicologists study a wide range of chemicals, from industrial substances to natural toxins, examining both acute and chronic exposure scenarios. Toxicology is essential in fields including medicine, public health, environmental science, and regulatory affairs, as it helps in assessing risks, managing exposures, and developing safety guidelines.

Pharmacology, while related, focuses specifically on the effects of drugs and their actions on the body, not strictly on poisons. Biochemistry delves into the chemical processes within and related to living organisms, rather than the study of toxic substances per se. Environmental science encompasses a broader range of studies related to the interactions between the environment and living organisms, including but not limited to toxicology.
