Sažetak
Metallurgical plants with their emission registers include dust, SO2, NOx, NH3, H2SO4, HCl, HF, HCN, H2S, CO, CO2, CH4, heavy metals and organic pollutions such as benzene, phenols, polycyclic aromatic hydrocarbon, polychlorinated biphenil, polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans. Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) belong to the group of persistent organic pollutions and represent a major hazard for the living environment. In order to calculate the emission of PCDD/Fs from metallurgical processes in the town of Sisak between 1950 and 2005, this research has built on experiences from developed countries, whereas the emission factor values from individual 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 PCDD/Fs from metallurgical processes in the Sisak took into account annual output of iron ore sinter, pig iron, and steel production. Between 1990 and 2000 the annual calculated emission values of these compounds from the metallurgical processes in Sisak accounted for the shares ranging from ~20 to ~39 % of their total emissions from all metallurgical processes in Croatia. Within the observed timeframe the town of Sisak did not experience any excessive air pollution by PCDD/Fs from the local metallurgical processes. It should be dully noted here that the metallurgical processes (especially sintering) were probably the biggest but not the only source of emission of these compounds in and around Sisak.
