PCDDs/Fs Pollution from Metallurgical Processes in the Town of Sisak, Croatia

In order to calculate the emission of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans from metallurgical processes located in the town of Sisak, Croatia, this research has built on experiences from developed countries, where the emission factor values from individual metallurgical processes have been taken from the reference data and used for the estimate of the emission of these pollutions in the European countries. The calculation of the emission polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans from metallurgical processes located in the town of Sisak took into account annual outputs of sinter, pig iron, steel blooms and steel billets, as well as steel casts. The metallurgical processes installed in the town of Sisak between 1950 and 2010 emitted from QI- TEQ=17 mg a-1 PCDDs/Fs in 2001 to QI-TEQ=5823 mg a-1 in 1989, depending on the activity of these processes. Within the observed period, the largest source of PCDDs/Fs emission was the iron ore sintering plant. Within the observed timeframe, the town of Sisak did not experience any excessive air, soil or water pollution by polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans from the local metallurgical processes.
