Dioxins and furans releases in Iranian mineral industries

► Emissions of PCDD/Fs of Iranian mineral industries were investigated and estimated. ► PCDD/Fs emissions from eight major metallurgical and cement plants were estimated. ► Samples from steel plant and cement plant were analysed for PCDD/Fs. ► The dioxins loads of the tested samples are unusually low. ► The result can confirm the necessity and feasibility of sampling gaseous effluents.
