Polychlorinated dibenzodioxins (pcdds), or simply dioxins, are a group of polyhalogenated organic compounds that are significant environmental pollutants they are commonly but inaccurately referred to as dioxins for simplicity, because every pcdd molecule contains a dibenzo-1,4-dioxin skeletal structure, with 1,4-dioxin as the central ring.
