英文摘要	Installing desulfurization operations and closing outdated facilities can effectively decrease pollutant emissions from iron ore sintering plants (IOSPs). Polybrominated dibenzo-p-dioxin and dibenzofuran (PBDD/F) emissions from different-sized IOSPs with different desulfurization operations were analyzed. The desulfurization operations' PBDD/F removal efficiencies were 53.6%-97.1%, and were higher for wet desulfurization operations than for semidry and dry operations. The removed PBDD/Fs were transferred to the desulfurization products. The removal efficiencies of PBDF homologues increased with the degree of bromination. A PBDD/F emission inventory for Chinese IOSPs was compiled. PBDD/F emissions in stack gases, desulfurization products, and discarded fly ash (previously ignored) from 2003 to 2015 were 1218, 400, and 245 g toxic equivalents, respectively. PBDD/F concentrations in stack gases and fly ash were higher for small IOSPs (<90 m(2)), indicating the importance of phasing them out. Indeed, in China, such phasing out decreased PBDD/F emissions in stack gases, desulfurization products, and discarded fly ash by 1021, 891, and 3253 g toxic equivalents, respectively, between 2003 and 2015. PBDD/F emissions in stack gases have been controlled in Chinese regions with the highest emissions, but PBDD/F emissions in desulfurization products and fly ash are increasing.
