1976 Daily Tel. 2 Aug. 11/8 He is to attempt to clean an experimental patch of land 100 yards square by the introduction of healthy micro-organisms of yeast and mould, which he hopes will ‘seed’ upon the poisonous substance, breaking down the molecules of TCDD (Tetrachlorodibenzo-dioxine).

1977 New Yorker 25 July 30/1 The samples of the chemical used in the experiments had contained uncharacteristically high levels of a toxic contaminant, 2,3,7,8 tetrachlorodibenzo-p-dioxin—commonly referred to as TCDD, or, by chemists familiar with the subject, either as tetra dioxin or simply as dioxin.

1980 National Geographic Aug. 181 TCDD—shorthand for 2,3,7,8-tetra~chlorodibenzoparadioxin, frequently simply called dioxin—is the inevitable by-product of the manufacture of the herbicides 2,4,5-T and silvex.
