AB  - The production of cement in China is accompanied by various emissions, such as 
      fine particulate matter, heavy metals, nitrogen oxides, sulfur oxides, carbon 
      dioxide.... Moreover, cement kiln presents a potential health risk to its 
      surroundings, linking to emissions of persistent organic pollutants (POPs), such 
      as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), in brief 
      dioxins. Flue gas samples were collected from five typical cement kilns during 
      twelve runs and were used to evaluate the levels and distribution of PCDD/Fs in 
      the emissions from cement kilns. The PCDD/Fs concentrations (136 congeners) and 
      I-TEQ values ranged from 2.3 to >40 ng/m(3) and 9.3~90.8 x 10(-3) ng I-TEQ/m(3), 
      respectively, which were lower than the emission standard in China (0.1 ng 
      I-TEQ/m(3)). In weight units, the dominant congeners were OCDD, 
      1,2,3,4,6,7,8-HpCDF, and OCDF; 2,3,4,7,8-PeCDF is the largest contributor (36-66 
      %) to the total I-TEQ value of twelve runs. HxCDF and TCDF were the first two 
      most abundant homologue groups (12-85 and 4-52 %), and the homologue 
      concentration decreased with rising chlorine number for PCDDs. In addition, there 
      was no marked difference in homologue profiles when solid wastes (refuse-derived 
      fuel and municipal solid waste) and hazardous wastes (DDT and POPs) were 
      combusted as supplemental fuels. The use of various supplemental fuels had no 
      obvious effect on the fingerprint of PCDD/F homologues. Moreover, there was no 
      significant difference in levels of PCDD/Fs emission due to the diversity of 
      production capacity, which were consistent with reported previously. Air 
      pollution control device had effect on the homologue profiles, and cement system 
      with electrostatic precipitators (ESP) had more fractions of octachloro congeners 
      to the total.
