Advanced Usage

• "Dioxin-like compounds": A term used to describe other chemicals that have a similar toxicological profile and mechanism of action to the most studied dioxin, TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin).
  • The risk assessment includes all dioxin-like compounds found in the sample.

Variants and Related Words

• TCDD (2,3,7,8-Tetrachlorodibenzo-p-dioxin): The most potent and widely studied congener of the dioxin family.
  • TCDD is often used as a reference point for the toxicity of other dioxins.

Synonyms
