ABSTRACT. This paper is based upon the report presented at 18th Symposium on Halogenated Environmental Organic Pollutants - Dioxin-98 (Stockholm, Sweden). The standard enthalpies of formation of four polychlorinated dioxins (PCDDs) have been measured in a rotating-bomb calorimeter. Basing on these results, the difference method was used to calculate group additivity values (9 constants) and to construct a complete set of enthalpies of formation of all 75 PCDDs.
