| Title | Dioxins, furans and polycyclic aromatic hydrocarbons emissions from a hospital and cemetery waste incinerator |
| Abstract | An experimental campaign was carried out on a hospital and cemetery waste incineration plant in order to assess the emissions of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polycyclic aromatic hydrocarbons (PAHs). Raw gases were sampled in the afterburning chamber, using a specifically designed device, after the heat recovery section and at the stack. Samples of slags from the combustion chamber and fly ashes from the bag filter were also collected and analyzed. PCDD/Fs and PAHs concentrations in exhaust gas after the heat exchanger (200-350 degrees C decreased in comparison with the values detected in the afterburning chamber. Pollutant mass balance regarding the heat exchanger did not confirm literature findings about the de novo synthesis of PCDD/Fs in the heat exchange process. In spite of a consistent reduction of PCDD/Fs in the flue gas treatment system (from 77% up to 98%), the limit of 0.1 ng ITEQ Nm(-3) at the stack was not accomplished. PCDD/Fs emission factors for air spanned from 2.3 up to 44 mu g ITEQ t(-1) of burned waste, whereas those through solid residues (mainly fly ashes) were in the range 41-3700 mu g ITEQ t(-1). Tests run with cemetery wastes generally showed lower PCDD/F emission factors than those with hospital wastes. PAH total emission factors (91-414 mu g kg(-1) of burned waste) were in the range of values reported for incineration of municipal and industrial wastes. In spite of the observed release from the scrubber, carcinogenic PAHs concentrations at the stack (0.018-0.5 mu g Nm(-3)) were below the Italian limit of 10 mu g Nm(-3). |
