Title Toxicology of chlorinated dibenzo-p-dioxins.
Bibliographic information Research Triangle Park, USA, Sep. 1973, Experimental issue No.5, p.87-99. 17 ref.
Abstract Experiments were carried out using various animal species to evaluate the toxicity of some chlorinated dibenzodioxins. The compounds used were: 2,7-dichlorodibenzo-p-dioxin (2,7-DCDD); 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD); 1,2,3,4-tetrachlorodibenzo-p-dioxin (1,2,3,4-TCDD); hexachlorodibenzo-p-dioxin (HCDD); and octachloro-dibenzo-p-dioxin (OCDD). Tests were conducted to estimate acute lethality, acnegenic activity, teratogenicity, embryotoxicity and eye irritative effects. Some gross pathological and histopathological examinations were performed. The results show that: 2,3,7,8-TCDD has an unusually high toxicity; 2,7-DCDD and OCDD have a low toxicity; HCDD is highly toxic but less toxic than 2,3,7,8-TCDD; isomers of the same dibenzo-p-dioxin vary in toxicological properties, making it important to identify them specifically.
