2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo-p-dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2.
All Irish pork products were withdrawn from sale both nationally and internationally. Main article: 2008 Irish pork crisis In this case the dioxin toxicity was found to be mostly due to dioxin-like polychlorinated dibenzofurans and polychlorinated biphenyls , and the contribution from actual polychlorinated dibenzodioxins was relatively low.
Dibenzo-1,4-dioxin, also dibenzodioxin or dibenzo-p-dioxin (dibenzo-para-dioxin), is a polycyclic heterocyclic organic compound in which two benzene rings are connected by a 1,4-dioxin ring. Its molecular formula is C 12 H 8 O 2. The two oxygen atoms occupy opposite (para-) positions in the six-membered dioxin ring.
