Definition of dioxins:
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are two groups of

tricyclic, chlorine-substituted, organic compounds. The number of chlorine substituents on the benzene rings may range from one to eight, which means 75 theoretical possible PCDDs and 135 possible PCDFs congeners, identified in general by the name “dioxins”. Dioxins are non-polar, lipophilic and persistent organic pollutants (POPs), which are able to biomagnify and bioconcentrate in the food web and cause a

whole spectrum of potentially serious health problems. [1]
This is the common definition for dioxins, other definitions can be discussed in the article
