What Is Toxicology?

"All substances are poisons: there is none which is not a poison. The right dose differentiates a poison and a remedy." Paracelsus (1493-1541)

Although poisons and poisoning episodes have been known about since ancient times, toxicology as a separate scientific field is relatively new. Although people have always wanted to ensure their health and safety, making inferences about dangerous compounds requires knowledge. 

This was first accomplished through trial and error, with compounds being examined to determine which were safe and which should be avoided. The toxicity of snakebite venom and its treatment have been documented in written records that date back to approximately 450 BCE. According to popular belief, Cleopatra herself killed herself by biting herself with an asp, albeit this story may be more fiction than fact.

Many naturally occurring toxins were likewise well known to the Greeks and Romans. In actuality, poisoning death was a prevalent method of capital punishment. For instance, Socrates was condemned to consume poisoned hemlock because he was accused of corrupting Athens' youth and refusing to acknowledge the official state deities. Over the decades, numerous skilled poisoners have been used to eliminate opponents of all colors, spouses, and other family members.

The 20th century is distinguished by a high degree of toxicological knowledge. They found DNA and other biochemicals that keep cells functioning. We are now learning more about the molecular level of harmful effects on cells and organs. Changes in particular biological molecules and biochemicals are known to be the cause of almost all hazardous consequences.

The broad discipline of toxicology freely incorporates ideas from the fundamental sciences. Three specialized fields of modern toxicology environmental, clinical, and forensic have emerged as a result of a variety of issues and uses. 

1. Environmental toxicology 

The main focus of environmental toxicology is the detrimental consequences of substances that are accidentally encountered because they are present in the food chain, the atmosphere, or in places of employment or recreation. Principles and methods from other disciplines, including as biochemistry, cell biology, developmental biology, and genetics, are extensively included into environmental toxicology. The assessment of environmental toxins, environmental monitoring for toxins, the impact of toxins on biotic and abiotic ecosystem components, and the metabolism and biological and environmental fate of toxins are some of its main areas of interest.

Development across time

2. Clinical toxicology


The detrimental effects of chemicals that are purposefully given to living things in order to achieve a certain effect are the focus of clinical toxicology, a branch of medicine. The toxicologist is concerned in the negative or side effects of the chemical in question if the intended impact is helpful to the organ (therapeutic). 

3. Forensic toxicology


The area of toxicology that focuses on the medical-legal elements of the detrimental effects of chemicals or poisons is called forensic toxicology.



Definition of Poison
Finding a succinct yet thorough definition of poison is challenging. A poison is any chemical that damages or kills a living thing when it is absorbed into it or acts locally on its tissues. 

4. Economic Toxicology

Food, beverages, medications, and other items that fall under this category have a direct or indirect impact on the nation's economy. For example, pure food is valuable in the commercial export market and promotes good health


Food contamination may result from unintended, accidental, or deliberate adulteration to increase profits. At a high temperature, many of the impurities in freshly cooked food would be removed. The poisoning caused by cyanogenic glycosides by consuming raw, uncooked cassava (tapioca) in Africa is an intriguing example.

(ii) Drug Toxicology




It is a subfield of toxicology that focuses on figuring out how xenobiotics harm living things.


It is a branch of toxicology that focuses on using laws to put particular restrictions on the release of chemicals into the environment. For this aim, state and federal governments write and enact laws, which are then implemented by regulatory agencies.
