AB  - Emissions from two typical cement kilns co-processing different kind of hazardous 
      waste were analyzed for 143 congeners of polychlorinated dibenzo-p-dioxins and 
      dibenzofurans (PCDD/Fs), polychlorinated biphenyls, polychlorinated naphthalenes, 
      polybrominated dibenzo-p-dioxins and dibenzofurans, and polybrominated diphenyl 
      ethers. The congener distributions in different process stages were investigated. 
      One of the plants co-processed waste chemical reagents from laboratories. The 
      emission factor (TEQ basis) for the plant was 2.09 ng WHO(2005) TEQ/t, with the 
      kiln head and the kiln back end contributing 1.18, 0.91 ng WHO(2005) TEQ/t, 
      respectively. The other plant co-processed municipal waste incineration fly ash. 
      The emission factor for the plant was 0.12 ng WHO(2005) TEQ/t, with the kiln head 
      and the kiln back end contributing 0.022, and 0.10 ng WHO(2005) TEQ/t. These 
      results indicate that co-processing of waste containing reagents from 
      laboratories may lead to higher emission levels than co-processing of other types 
      of waste. The congener patterns of persistent organic pollutants (POPs) in ash 
      samples from the humidifier tower were similar to those in samples from the bag 
      filter at the kiln back end. The correlation coefficients of five pollutants 
      between the humidifier and bag filters samples were generally high, which 
      indicated that conditions in those two stages similarly favored the formation of 
      these POPs. Comparison of the concentrations for different process stages 
      suggested that the main stage for formation of unintentional POPs was the 
      humidifier tower. These results improve our understanding of emission 
      characteristics and could be used for simultaneous control of multiple POPs.
