Abstract :
[en] PCDD/Fs and dl-PCB in ash and flue gas emission samples, generated by an incineration plant of clinical and industrial waste, were investigated at the sole incineration waste plant currently operating in Northern Algeria. We studied the incineration of six types of waste including bank notes, CD-ROM, clinical waste, sludge inks, expired pharmaceuticals and tobacco. For each of them, we collected gaseous emissions and ashes after incineration. Final extracts of the different wastes were analyzed by high-resolution gas chromatography coupled to high-resolution mass spectrometry (HRGC–HRMS). Flue gas results indicated that the emission concentrations of PCDD/Fs, expressed in I-TEQs, were in the range of 22.78 – 1647.86 pg I-TEQ Nm-3, while for dl-PCB in flue gas, expressed in WHO-TEQs, levels reported were between 0.66 – 46.97 pg WHO-TEQ Nm-3. Regarding incinerator ashes, levels span from 1.68 to 879.56 pg I-TEQ g-1 for PCDD/Fs and 0.1 to 28.30 pg WHO-TEQ g-1 for dl-PCBs. The contribution of dl-PCBs to the sum TEQ was relatively low for all matrices analyzed. A positive and consistent correlation was obtained between the 2,3,4,7,8-PeCDF concentration and I-TEQ PCDD/Fs values in flue gas and ash samples. XRF method was used to determine the major inorganic compounds that could be responsible of the inhibition of PCDD/Fs formation.
