   Dioxin
   Dioxin: One of a number of poisonous petroleum-derived chemicals which are produced when herbicides (substances used for killing plants) are made or when plastics are burned. Dioxins are chemically dibenzo-p-dioxins. One of the best known is TCDD (2, 3, 7, 8-TCDD). Dioxins cause skin disease (chloracne). In animal tests, dioxins are teratogens (age ...

    Dioxin
    `Dioxin` is a name for either one of two organic chemical compounds which are isomers and whose chemical structures are shown at right. These isomers are called `1,2-dioxin` (or `o`-dioxin`) and` 1,4-dioxin` (or `p`-dioxin`). Both dioxins are heterocyclic compounds which have the chemical formula C4H4O2. The ortho isomer 1,2-dioxin is very unstable due to its peroxide-like characteristics. The known properties of 1,4-dioxin are listed in the in...
