AB  - Iron ore sintering (SNT) processes are major sources of unintentionally produced 
      chlorinated persistent organic pollutants (POPs), including polychlorinated 
      dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), and 
      polychlorinated naphthalenes (PCNs). However, few studies of emissions of 
      brominated POPs, such as polybrominated dibenzo-p-dioxins/dibenzofurans (PBDD/Fs) 
      and polybrominated diphenyl ethers (PBDEs), during SNT have been performed. Stack 
      gas and fly ash samples from six typical SNT plants in China were collected and 
      analyzed to determine the concentrations and profiles of PCDD/Fs, PCBs, PCNs, 
      PBDD/Fs, and PBDEs, as well as any correlations among these compounds. The 
      PCDD/F, PCB, PCN, PBDD/F, and PBDE emission factors were 2.47, 0.61, 552, 0.32, 
      and 107mugt(-1), respectively (109, 4.07, 10.4, 4.41 and 0.02ng toxic equivalents 
      t(-1), respectively). PCBs were the most abundant compounds by mass, while PCNs 
      were the next most abundant, contributing 51% and 42% to the total POP 
      concentration, respectively. However, PCDD/Fs were the dominant contributors to 
      the chlorinated and brominated POP toxic equivalent concentrations, contributing 
      89% to the total toxic equivalent concentration. The PCDD/F and other chlorinated 
      and brominated POP concentrations were positively correlated, indicating that 
      chlorinated and brominated POP emissions could be synergistically decreased using 
      the best available technologies/best environmental practices already developed 
      for PCDD/Fs.
