“…However, major contributions were from HpCDDs, OCDD and TCDF. The congener profiles in cement kilns were in agreement with those reported by Karstensen (2008) and Ames et al (2012). Fig.…”

“…This low flow rate might influence the distribution of OCDD between gas phase and particulate phase and preferential adsorption of OCDD in particulates (due to its lower vapour pressure). Ames et al (2012) also observed similar phenomenon with relatively high OCDD in emission samples from two cement kilns.…”

“…4 demonstrates that the contribution of OCDD congener in fly ash samples ranged from 27% to 91% for CK3 and CK2, respectively. It is interesting to note that while the contribution of OCDD congener in fly ash of the CK3 (27%) was in a typical range of reported value (Ames et al, 2012), those of CK2 (91%) was relatively elevated. A reason for this phenomenon is still unclear.…”

“…However, compared with the available data in the world, the results of this study are within the typical range of values reported elsewhere. For example, low TEQ concentrations in dust samples of cement kilns were reported in several studies in the UK (0.001-30.0 pg TEQ/g dry wt., Ames et al, 2012) and Germany (1.0-40.0 pg TEQ/g dry wt., Zemba et al, 2011).

Stack gas and fly ash samples were collected in two steel plants and three cement kiln plants for the determination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs). A standard sampling method (U.S EPA method 23) was used following the requirements for isokinetic sampling of stack gas emission. The quantification of PCDD/Fs was done by high resolution gas chromatography, coupled with high resolution mass spectrometry (HRGC/ HRMS). The results demonstrated that PCDD/F concentrations in steel plants varied from 0.234 to 0.577 ng/Nm 3 on a mass basis, and 0.048 to 0.166 ng/Nm 3 on a TEQ basis. In cement kiln plants, the mass concentration varied from 0.280 to 5.32 ng/Nm 3 , while TEQ concentration varied from 0.033 to 0.837 ng TEQ/Nm 3 . In general, PCDD/F emissions from steel industry in Vietnam were slightly lower than those reported for European Union, and were comparable to those reported for Taiwan and Korea. A similar trend was observed for the emissions of PCDD/Fs from cement kiln industry in Vietnam. PCDD/F emission factors for steel and cement kiln industries were also estimated to compare with the guidelines of the UNEP for persistent organic pollutants (POPs) inventory.

“…Formation and emission of PCDD/Fs from a cement kiln processing a solid fuel recovered from municipal solid waste has been studied [18,19]. Dioxins form in cement kilns, and their release and impact on surrounding environment has been demonstrated [20][21][22][23][24]. However, to date, incineration of MSWI fly ash in a cement kiln has not been performed on an industrial scale or in any pilot studies.…”

The European and American methods for the determination of polychlorodibenzo-p-dioxins and polychlorodibenzofurans in stationary source emissions require a high-resolution mass spectrometer detector. At the same time, all of the 17 toxic 2,3,7,8-chlorine-substituted isomers have to be separated by an appropriate chromatographic method. The resulting analysis has long runtimes and sometimes a double-column run is needed, which results in a huge waste of time, money and manual labor. To obtain a fast and cost-effective but still reliable analytical system, a single-column gas chromatography with hydrogen as carrier gas and tandem mass spectrometry detection is proposed. The use of hydrogen as the carrier gas is a good choice to shorten runtimes and improve the chromatographic resolution, while tandem mass spectrometry is a well-known alternative for this analysis. All the chromatographic and mass spectrometric parameters fill the requirements of the reference methods with a 35% reduction of runtimes. The accuracy is tested with three fly ash samples of a proficiency interlaboratory test. A good correlation between the results is obtained (R = 0.992, slope = 0.9675), and no coelutions are noted. The system robustness is tested during 5 years of constant use and the maximal relative standard deviation of the relative response factor is 18.8%.
