It usuallytakes a few weeks to analyze dioxin concentrations and dioxin-TEQ (toxicity equivalency quantity) in fluegases from municipal solid waste (MSW) incinerators by a standard method provided by Japanese industrial standard (JIS 0311). To reduce the required time for analysis, we have developed a new on-line measuring system for furans homologues. This system is composed of a sensitive and robust vacuum ultraviolet (VUV) single-photon ionization (SPI) ion trap (IT) time-of-flight mass spectrometer (VUV-SPI-IT-TOFMS) and automatic sampling/concentrating process. In this work, pentachloro-dibenzofuran (P5CDF) was selected as an index homologue in chlorinated dibenzo-p-dioxin/ furan homologues (DXNs) because its concentration and I-TEF (international toxicity equivalency factor), which are 2,3,4,7,8-P5CDF is 0.5 and 1,2,3,7,8-P5CDF is 0.05, are high and the concentration correlates closely with the total amount of dioxin-TEQ. The lowest detectable limit, 1 pg (0.001 ng-TEQ/m3 N) was demonstrated by laboratory tests. This system underwent a field test at several actual MSW plants and the tests revealed the following: (a) This system is applicable for dioxin-TEQ evaluation from actual MSW incinerators. (b) It can continuously monitor P5CDF in a fluegas for 7 months. (c) The frequency of the measurements is once every 2-6 h, depending on the concentration of P5-CDF.

International audienceDue to the incomplete mineralisation of some organic compounds during the incineration of municipal solid waste, gaseous emissions are loaded with a large amount of particulate matter, undesirable elements and toxic molecules. Typically, an incinerator of urban solid waste produces large flows of hot gaseous emissions to be purified before being released into the atmosphere. In this paper, treatments of flue gas from a typical municipal waste incinerator are described. The first step is an energy recovery system through heat exchangers to make steam or hot water. Steam is used to produce electricity via a turbine. The economic balance of the total system is very often dependent on the heat recovery. The second step involves particle removal technologies. Different systems are available such as cyclones, scrubbers, electrostatic precipitators or baghouse filters. The third step is the removal of numerous molecule families such as acid compounds (SOx, HCl, HF), nitrogen oxides (NOx), metal species and many organic compounds. The latter include dioxins, furans and volatile organic compounds. Some treatment processes are described according to the pollutant family
