“…The results obtained confirm that there were no significant losses of the target analytes (recoveries >80%). These results agree with a previous study that evaluated stability during storage of 90 VOCs in Tenax TA/Carbograph 1TD tubes in which it was found that there was no significant loss of analytes after 3 and 7 days of storage. All samples evaluated in the present study have been analyzed within 24 h of sampling.…”

This study describes the development of an analytical method based on active collection in a multisorbent Tenax TA/Carbograph 1TD tube, followed by thermal desorption and GC-MS for the determination of 16 volatile organic compounds in air samples. The analyzed compounds include ozone precursors and odor-causing compounds belonging to different chemical families (sulfur- and nitrogen-containing compounds, aldehydes, and terpenes). Two types of sorbents were tested and desorption conditions (temperature, time, and sampling, and desorption flow) were evaluated. External calibration was carried out using the multisorbent bed. Method detection limits in the range 0.2-2.0 μg m(-3) for 1 L samples were obtained. The method was applied for determining the target compounds in air samples from two different wastewater treatment plants. Most compounds were detected and toluene, limonene, and nonanal were found in particularly high concentrations with maximum values of 438, 233, and 382 μg m(-3), respectively.

“…Passive headspace solid phase microextraction (HS‐SPME) were performed using a CUSTODION® SPME syringe (Perkin Elmer Torion Technologies, American Fork, UT, USA) with a divinylbenzene/polydimethylsiloxane (DVB/PDMS; 65 μm) stationary phase; 15 while dynamic headspace needle trap extraction (HS‐NT) was carried out on a CUSTODION® NT (Perkin Elmer Torion Technologies) composed of three adsorption phases (1 mg, 60–80 mesh Tenax TA/1.6 mg, 60–80 mesh Carboxen 1016/1.5 mg, 60–80 mesh Carboxen 1003) 16 . The NT device was connected to a Clairion™ air sampling pump at a constant flow rate of 50 mL/min for plant extractions 17 . Before using the devices for the first time, SPME and NT were conditioned according to the manufacturer's instructions.…”

Introduction: In situ analysis of volatile organic compounds (VOCs) emitted by plants is an important challenge in chemical ecology. The traditional approach usually consists in trapping compounds using dynamic headspace extraction (DHS) in-field, followed by gas chromatography analysis coupled with mass spectrometry (GC-MS and/or GC-FID) in the laboratory. Objectives: In this study, we evaluated the use of the new portable Torion T-9 GC-MS system for rapid and in situ analysis of VOCs emitted by fine lavender and lavandin species. Material and methods: All field analyses were performed using a person-portable low-thermal mass GC system coupled with a miniature toroidal ion trap mass analyser (ppGC-ITMS): Torion T-9 portable GC-MS. Subsequently, multivariate statistical analyses were performed to determine chemical differences between species. Results: Thirty compounds were separated and detected in all lavender aboveground samples in only 3 min of analysis. Conclusions: The portable GC-MS device enabled a rapid in-field distinction of Lavandula species based on their detected volatile profiles. In this study, we evaluate the use of the new portable TORION T-9 GC-MS system for rapid and in situ analysis of volatile organic compounds (VOCs) emitted by fine lavender and lavandin species. Thirty compounds were separated and detected from all lavender aerial part samples in only three minutes of analysis. The ability to quickly characterize the VOCs emitted by plants in the field attests of this portable device's potential compared to long laboratory analyses.

“…Average benzene found within the degassing carters in Nisyros Island was 23.75 μg/m 3 during September 2010 and 2012 (Tassi et al., 2013). Samples were collected from two different sites near an Industrial WWTP located in the South Industrial Complex, Tarragona area of Spain, during November 2008 and the levels of benzene were 1.31 and 1.46 μg/m 3 (Ramírez et al., 2011). Air samples were collected around the different industries in Daegu, Korea during June–September 2004 and that the benzene concentrations were; around wastewater incinerator- 218.1 ± 346.5 ppb, food manufacturing industry - 5.2 ± 0.9 ppb, chemical manufacturing industry 10.6 ± 7.9 ppb, excretion disposal facilities - 4.6 ± 0.3 ppb, sewage & wastewater processing facilities 4.5 ± 0.0 ppb, general garbage incinerator - 3.6 ± 0.0 ppb, fiber manufacturing industry - 6.8 ± 2.4 ppb, paper manufacturing industry - 4.8 ± 0.1 ppb and food manufacturing industry with alcohol - 4.6 ± 0.3 ppb (Choi et al., 2009).…”

Benzene is a proven carcinogen. Its synergistic action with other pollutants can damage different components of the biosphere. Literature comparing the air quality standards of benzene, its monitoring methods and global concentrations are sparse. This study compiles the worldwide available air quality standards for benzene and highlights the importance of strict and uniform standards all over the world. It was found that out of the 193 United Nation member states, only 53 countries, including the European Union member states, have ambient air quality standard for benzene. Even where standards were available, in most cases, they were not protective of public health. An extensive literature review was conducted to compile the available monitoring and analysis methods for benzene, and found that the most preferred method, i.e, analyzing by Gas Chromatography and Mass spectroscopy is not cost effective and not suitable for real-time continuous monitoring. The study compared the concentrations of benzene in the indoor and outdoor air reported from different countries. Though the higher concentrations of benzene noticed in the survey were mostly from Asian countries, both in the case of indoor and outdoor air, the concentrations were not statistically different across the various continents. Based on the analyzed data, the average benzene level in the ambient air of Asian countries (371 μg/m3) was approximately 3.5 times higher than the indoor benzene levels (111 μg/m3). Similarly, the outdoor to the indoor ratio of benzene level in European and North American Countries were found to be 1.2 and 7.7, respectively. This compilation will help the policymakers to include/revise the standards for benzene in future air quality guideline amendments.
