Definition of toxicity

toxicitynoun

độc tính

/tɒkˈsɪsəti//tɑːkˈsɪsəti/

The word "toxicity" has its roots in the Greek words "toxon," meaning "bow" or "arrow," and " epidemiemai," meaning "to fall upon" or "to occur." In the early 19th century, chemists began using the term "toxicology" to describe the study of the poisonous effects of substances. They derived the term from the concept of poison as a "dart" or "arrow" that could harm or kill. Gradually, the suffix "-ity" was added to form the term "toxicity," which specifically refers to the quality or state of being poisonous. In the late 19th century, the term gained widespread use in scientific and medical contexts to describe the degree to which a substance harms or poisons living organisms. Today, toxicity is a ubiquitous concept in fields such as chemistry, medicine, and environmental science, where it is used to assess the potential harm of substances and develop strategies for mitigating or preventing harm.
