“…These improvements are in accordance with the analytical criteria of HRGC/HRMS and represent enhanced selectivity. In recent years, analysis of dioxins from matrices including food, feed, fats, sewage sludge, and fly ash samples using GC-MS/MS have revealed sensitivity and accuracy comparable with HRGC/HRMS [15,[18][19][20][21][22][23]. Therefore, GC-MS/MS could, in principle, be employed for analysis of POPs, such as dioxins, and for analysis of harmful and toxic substances in various fields.…”

The applicability of gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS) for determination of dioxins in soil was investigated. The analytical method was validated based on US Environmental Protection Agency (EPA) Method 1613 and European Union (EU) Regulation No. 709/2014 for selectivity, linearity of sensitivity, and instrumental limits of quantification (iLOQs). Method development commenced with determination of retention times for 17 native polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) and selection of characteristic ions from GC-MS/MS spectra. The linearity was measured using 1613 standard solutions (CS1-CS5) containing 0.5 to 200 ng/mL tetrachlorodibenzo-p-dioxin/furan (TCDD/F) congeners, 2.5 to 1000 ng/mL pentachlorodibenzo-p-dioxin/furan (PeCDD/F) to heptachlorodibenzo-p-dioxin/furan (HpCDD/F) congeners, and 20 to 2000 ng/mL octachlorodibenzo-p-dioxin/furan (OCDD/F) congeners. The correlation coefficient (R 2) values ranged between 0.9990 and 0.9999, and the iLOQ values ranged from 0.052 to 0.350 pg/μL for TCDD/F congeners, with a relative standard deviation of 2.7-9.6%. The entire analytical method was verified by analysis of certified reference materials (BCR-529 and BCR-530), and the recoveries were 71.79-103.87% and 81.50-103.12%, respectively. Thus, the GC-MS/MS system provides an alternative to GC-high-resolution MS for the simultaneous determination of TCDD/F congeners in soil.

“…Incineration has become one of the key treatment processes for municipal solid waste (MSW). However, polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), generated during the incineration process, may induce environmental pollution and cause serious social problems [1][2][3]. To evaluate the influence of the exhausted PCDD/Fs to organisms, the criterion of international toxic equivalence quantity (I-TEQ) was proposed via employing the concentrations of 17 toxic PCDD/Fs congeners [4].…”

Chlorinated benzenes are typical precursors and indicators for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) emissions from waste incinerators. Online and real-time monitoring of chlorobenzenes is a challenge due to their low concentration and complex nature of the flue gas. In this work, a continuous online monitoring system was built for detection of trace chlorinated benzenes based on a time-of-flight mass spectrometer (TOFMS). A single photon ionization (SPI) source based on a radiofrequency-excited windowless vacuum ultraviolet (VUV) lamp was developed for the first time to eliminate the signal attenuation resulting from the contamination of magnesium fluoride windows and to avoid the fragment ions. An automatic enrichment system including three parallel Tenax TA adsorption tubes was designed and coupled to the TOFMS to achieve the required ultrahigh sensitivity. The limits of quantitation at 7.65, 5.37 and 6.77pptv were obtained for monochlorobenzene (MCBz), dichlorobenzene (DCBz) and trichlorobenzene (TrCBz), respectively, within a 29-min analytical period. Moreover, this apparatus was applied to continuously online monitor the actual flue gas from a waste incinerator for three months. During this period, the concentrations of MCBz, DCBz and TrCBz detected in the flue gas were in the range of 100-1200, 50-800 and 50-300pptv, respectively. The relative standard deviation (RSD) of the sensitivity for the windowless VUV lamp ion source was 9.71% evaluated by the internal standard benzene over the 3-months flue gas monitoring. These results demonstrated the capability of this method in long-term analysis of the trace chlorinated benzenes in the flue gas.

“…Waste incinerator flyash and air pollution control system residues represent a major emission of PCDD/PCDF to land [5][6][7]. It is estimated that more than 1 million tonnes of hazardous flyash and air pollution control residues are generated in Europe each year from the incineration of municipal solid waste, much of which is landfilled [7,8].…”

“…It is estimated that more than 1 million tonnes of hazardous flyash and air pollution control residues are generated in Europe each year from the incineration of municipal solid waste, much of which is landfilled [7,8]. In addition, PCDD/PCDF have been detected in sewage sludge and reported in several studies [6,[9][10][11][12][13][14]. Certain types of contaminated industrial soils are also reported to contain significant concentrations of PCDD/PCDF [15][16][17].…”
