“…Different feeding wastes and APCDs probably explain the discrepancy between studies. The total PCB emission factors (0.0207 mg WHO 2005 -TEQ/ ton-waste [0.0204 mg WHO 1998 -TEQ/ton-waste]) observed from the MSWI in this study were comparable to that (0.014 ng WHO 1998 -TEQ/kg) from woodstove combustion in the United States (Gullett et al, 2003), but significantly lower than those (6.9-98.3 [mean ¼ 26.4] mg WHO 2005 -TEQ/ton) from 43 small MSWIs (Choi et al, 2008).…”

No information is currently available on the emission of brominated flame retardant (BFR) compounds from stack flue gases of municipal solid waste incinerators (MSWIs) because of the limitations of standard methods of BFR sampling and analysis. This study presents sample cleanup procedures that are combined with a multiple column approach to determine the quantities of five persistent organic pollutants (polychlorinated dibenzo-p-dioxins/ dibenzofurans [PCDD/Fs], polybrominated dibenzo-p-dioxins/dibenzofurans [PBDD/Fs], polybrominated diphenyl ethers [PBDEs], polychlorinated biphenyls [PCBs], and polybrominated biphenyls [PBBs]) simultaneously from single stack gas samples collected from a large-scale MSWI in Taiwan. Mean concentrations of PCDD/Fs, PBDD/Fs, PCBs, PBDEs, and PBBs in the flue gases of MSWI were 0.0719 ng WHO-TEQ/(N Á m 3 ), 0.00169 ng WHO-TEQ/(N Á m 3 ), 0.00546 ng WHO-TEQ/(N Á m 3 ), 20.7 ng/(N Á m 3 ), and 0.958 ng/( N Á m 3 ), respectively. Emission factors of PCDD/Fs, PBDD/Fs, PCBs, PBDEs, and PBBs were 0.300 mg WHO-TEQ/ton-waste, 0.00667 mg WHO-TEQ/ton-waste, 0.0207 mg WHO-TEQ/ton-waste, 84.5 mg/ton-waste, and 1.05 mg/ton-waste, respectively. Therefore, the emissions of not only PCDD/Fs but also BFRs from MSWIs should be of concern and further investigation is needed.

“…For one plant, H12, the concentration of PCDD/Fs in flue gas was nearly 1 ng TEQ/Nm 3 . The high emissions of HWIs may result from poor performance of air pollution control devices and the influence of memory effect caused by start-up on PCDD/Fs emission of incinerators (Chi et al, 2006;Wang et al, 2007;Choi et al, 2008). In this research, the amount of activated carbon injection in H12 (0.05 g/Nm 3 flue gas) is less than the average of other 11 incinerators (1.75 g/Nm 3 flue gas).…”

In order to investigate the dioxin emission levels of hazardous waste incinerators (HWIs), and estimate their emission factors to the atmosphere, flue gas samples were collected from 12 HWIs in China, and analyzed for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). Eleven HWIs are located in the south-eastern coastal areas of China, with rotary kilns being is the most widely used type of incinerator (more than 50% of the units), followed by pyrolysis kilns. Eleven incinerators had their emission levels below the current standards in China, while only four facilities exhibited emission levels below the European Union's limits. The highest concentration of PCDD/Fs, at nearly 1 ng TEQ/Nm 3 , was in the flue gas collected from an HWI with a waste burning capacity of 5 ton/d. This result was significantly higher than the values found for the other 11 incinerators, and thus was due to the poor performance of air pollution control devices and the influence of memory effects caused by PCDD/Fs emissions related to the start-up of the incinerator. In addition, the high dioxin emissions of this HWI were related to its feeding wastes, which mainly consisted of chemical industry waste residue with high a chlorine content. The emission factors of PCDD/Fs from the HWIs examined in this work were in the range of 0.27-18 µg TEQ/ton hazardous waste, with an average value of 3.74 µg TEQ/ton hazardous waste. It is estimated that 5.0 g TEQ of PCDD/Fs was released from HWIs to the atmosphere in China in 2010, which is less than that seen in 2004. The results of principal component analysis and hierarchical cluster analysis show all the investigated HWIs can be assigned to three groups, as verified by the results of nonparametric statistics. OCDD, 2,3,4,7, 1,2,3,4,7, are the main congeners in these three groups.

“…The concentration of dioxins from municipal waste incineration plants in the flue gas stream is usually from 0.001 to 50 ng TEQ/m 3 , depending on the exhaust gas treatment system [6][7][8]. Of course, the highest concentrations occur when there are no exhaust gas treatment systems.…”

In Poland, incineration is a relatively new method of waste treatment. Modern installations for waste incineration have two functions: they reduce the quantity (volume) of the waste and are a source of electricity and/or heat. During all combustion processes including waste incineration, polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCD/Fs) (well known as dioxins) are formed. These compounds are considered to be extremely dangerous for living organisms including human beings. Dioxins are formed in any process of combustion of solid and liquid fuels in the presence of chlorine, oxygen and organic matter at appropriate temperatures. Combustion processes also occur during cigarette smoking, which is also a source of dioxin emissions. Although smoking has been classified as a less important source of dioxins in the environment, it directly affects our health. This work’s aim is to determine and compare the degree of harmfulness caused by the amount of inhaled dioxins: cigarette smoking or living near a waste incineration plant. Based on literature and experimental data, the concentration of dioxins in cigarette smoke and exhaust gases generated by municipal waste incineration plants as well as number of dioxins absorbed per day by the body will be presented.
