By contrast, a toxin is a poison produced naturally by an organism (e.g. plant, animal, insect). [2] The 2011 book A Textbook of Modern Toxicology states, "A toxin is a toxicant that is produced by a living organism and is not used as a synonym for toxicant—all toxins are toxicants, but not all toxicants are toxins.
Poison is a related but broader term that encompasses both toxins and toxicants; poisons may enter the body through any means - typically inhalation, ingestion, or skin absorption. Toxin, toxicant, and poison are often used interchangeably despite these subtle differences in definition.
Toxicity can also vary with the organism's placement within its food web. Bioaccumulation occurs when an organism stores toxicants in fatty tissues, which may eventually establish a trophic cascade and the biomagnification of specific toxicants. Biodegradation releases carbon dioxide and water as by-products into the environment. This process ...

A toxicologist working in a lab (United States, 2008)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 [1] and the practice of diagnosing and treating exposures to toxins and toxicants.
A box model explaining the processes of toxicokinetics and toxicodynamics. While toxicokinetics describes the changes in the concentrations of a toxicant over time due to the uptake, biotransformation, distribution and elimination of toxicants, toxicodynamics involves the interactions of a toxicant with a biological target and the functional or structural alterations in a cell that can ...
[6] [7] The difference between venom and poison is the delivery method of the toxin. [6] Venoms are toxins that are actively delivered by being injected via a bite or sting through a venom apparatus , such as fangs or a stinger , in a process called envenomation , [ 8 ] whereas poisons are toxins that are passively delivered by being swallowed ...
The epigenome can be influenced, or “reprogrammed,” by environmental factors like stress, diet, drugs, pollution, and toxicants. Resulting changes can be passed down from cell to cell as they ...
