| Abstract: | A chemical method for destroying the 2,3,7,8-TCDD is reported; it provides gradual and progressive substitution of the chlorine atoms by hydrogen atoms. The dehalogenation is promoted by a mixture made up of polyethyleneglycols (high molecular weight) of a weak base (K2 CO3) and of an inorganic peroxide (Na2 O2) which begins the radical process. The organic chlorine is transformed into inorganic chloride.The reaction mixture administered to male guinea-pigs did not lead to any direct or histological effect. |
