Summary of results of PCDDs analyses from incinerator effluents

Polychlorinated dibenzo-p-dioxins and dibenzofurans in the ambient atmosphere of Bloomington, Indiana

“…We chose Bloomington, IN, because of the proposed construction of an incinerator that could burn PCB-contaminated material along with the town's municipal waste. Given previous evidence on the production of PCDD/F in municipal incinerators (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) and in PCB fires (9,10), this proposed incinerator could have a significant impact on Bloomington's air quality. Thus, this study was undertaken to provide base-line data against which the impact of this incinerator on local PCDD/F concentrations could be judged.…”

“…These combustion processes include the incineration of municipal wastes (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) and the combustion of automotive fuels (15); these processes generate complex mixtures of PCDD/F (i.e., PCDD + PCDF) with varying numbers of + Current address: Connecticut Agricultural Experiment Station, 123 Huntington St., New Haven, CT 06504. chlorine atoms and with varying sites of chlorine substitution, depending on fuel composition and combustion temperature. Because of the varying toxicities of PCDD/F, it is important to understand the processes and parameters that control the rate at which individual compounds undergo transformations while in the atmosphere.…”

Evaluation of gas-particle partition of dioxins in flue gas II: Estimation of gas-particle partition of dioxins in dust-rich flue gas by parallel sampling with different conditions

“…Some researchers estimated the gas-particle partition of PCDD/Fs on the basis of their partition in each collection device, and varying results are reported [1,[8][9][10][11][12][13]. Variations seem to be attributed to the obvious difference in temperature between flue gas and collection devices.…”

Incineration of polychlorinated biphenyls in high efficiency boilers: a viable disposal option

“…Additionally, it is well documented that both particulate and gaseous emissions from some municipal incinerators may contain measurable quantities of polychlorinated dibenzodioxins (PCDDs) and chlorinated dibenzofurans (PCDFs) (8)(9)(10)(11)(12)(13). As a consequence, some concerns can be offered for the presence of these toxicants as potential combustion byproducts during the incineration of polychlorinated biphenyls in high-efficiency boilers.…”

“…As a consequence, some concerns can be offered for the presence of these toxicants as potential combustion byproducts during the incineration of polychlorinated biphenyls in high-efficiency boilers. While these components have not typically been noted in controlled incineration process emissions such as high-efficiency boilers, numerous investigators have noted their presence under both controlled laboratory and actual field sampling activities (8,(14)(15)(16)(17)(18)(19). Buser et al reported that significant concentrations of numerous PCDD and PCDF isomers were formed during the pyrolysis of an Aroclor mixture (16).…”
