A large group of VOCs has been included in the class of air pollutants, therefore, their determination and monitoring using reliable and sensitive analytical methods represents a key aspect of health risk assessment. In this work, an untargeted approach is proposed for the evaluation of the exposure to volatile organic compounds of workers in an engine manufacturing plant by GC-MS measurements, coupled with Solid-Phase Microextraction (SPME). The analytical procedure was optimized in terms of SPME fiber, adsorption time, desorption time, and temperature gradient of the chromatographic run. For the microextraction of VOCs, the SPME fibers were exposed to the air in two different zones of the manufacturing factory, i.e., in the mixing painting chamber and the engine painting area. Moreover, the sampling was carried out with the painting system active and running (system on) and with the painting system switched off (system off). Overall, 212 compounds were identified, but only 17 were always present in both zones (mixing painting chamber and engine painting area), regardless of system conditions (on or off). Finally, a semi-quantitative evaluation was performed considering the peak area value of the potentially most toxic compounds by multivariate data analyses. VOCs Working Environments Indoor Air Quality Industrial Emissions Solid Phase Microextraction (SPME) Gas Chromatography - Mass Spectrometry (GC-MS). Figures Figure 1 Figure 2 Figure 3 Figure 4 INTRODUCTION The term VOCs (Volatile Organic Compounds) covers a wide range of chemical classes (including aromatic and aliphatic amines, ethers, aldehydes, ketones, esters, alcohols, acids, and halogenated hydrocarbons) with high vapor pressure and low water solubility. The natural sources of VOCs are mainly the sea, vegetation, soil, volcanoes, and rainwater (Huang et al. 2018). Many VOCs are chemicals produced and used by humans in the preparation of pharmaceuticals, paints, and refrigerants. Numerous studies have reported that VOCs may have short- and long-term harmful effects on human health and cause respiratory, neurological, and circulation diseases (Kumar et al. 2018; Zhang et al. 2020). Furthermore, VOCs affect air quality and climate change as precursors of ground-level ozone and secondary organic aerosol (Guo et al. 2017). Humans typically spend most of their time inside buildings, and this has prompted many field studies (Žitnik et al. 2010; Zhang and Zhu 2012). In closed environments, both residential and working, indoor air quality depends not only on building materials and furnishings (Schieweck and Salthammer 2009; Schieweck 2021), but also on human presence, the activity of occupants and their cleaning and personal care products (Tham 2016; González-Martín et al. 2021). Moreover, gases and/or particulates are also released from external sources, and all these aspects contribute to the overall VOC composition and air quality (Schalm et al. 2022). VOC fingerprints are usually evaluated by gas chromatography coupled mass spectrometry and for the sample extraction, SPME (Solid-Phase MicroExtraction) is one of the most used microextraction techniques for its ease of use and high extraction efficiency, in terms of the number and type of extracted compounds (Lord and Pawliszyn 2000; Nerín et al. 2009). SPME is a solvent-free technique that combines extraction, concentration, and clean-up into a single step, without requiring chemical-physical treatments; it is not invasive, and it does not change the environmental conditions of the sample, allowing the study of VOC production in real conditions (Ouyang and Pawliszyn 2006; Spadaccino et al. 2021). In this work, an untargeted approach is described for the characterization of VOCs in indoor working environments by SPME-GC-MS. The exposure to volatile organic compounds of workers in different areas of an engine manufacturing plant was evaluated at different stages of the working cycle. Several SPME fibers of different polarity and composition were used to extract the greatest number of compounds, identified by mass spectrometry analysis coupled with database searching. Finally, multivariate analyses were performed to explore similarities and differences in the VOC composition. MATERIALS AND METHODS Solid-Phase MicroExtraction (SPME) experimental conditions The microextraction process was carried out using an SPME device (Supelco, JVA Analytical Ltd., Ireland). Two fibers with different polarity were used: 85 µm carboxen/polydimethylsiloxane (CAR/PDMS), and 100 µm polydimethylsiloxane (PDMS), purchased from Supelco/Sigma-Aldrich (Bellefonte, PA, USA). The fibers were thermally conditioned following the manufacturer’s recommendations before their first use. Each SPME fiber was exposed to the air for 30 min at room temperature in two different areas of the manufacturing factory: in the mixing painting chamber (that is where the painting of the engines is carried out, area A) and the engine painting area (the working area adjacent to the engine painting room, zone B). The sampling was carried out with the factory active and running (hereinafter referred to as system on) and with the factory switched off (system off). The samples were analyzed in duplicate and blank runs were acquired before and after each GC-MS analysis. GC-MS analyses GC–MS analyses were performed using an Agilent 7890 apparatus (Little Falls, DE, USA) coupled with an Agilent 5975 mass selective detector. The SPME device was directly inserted into the GC–MS injection port; the injections were made in splitless mode using an SPME injection sleeve (0.75 mm I.D) with a desorption temperature and time of 250°C and 6 min, respectively. The chromatographic separations were carried out using the analytical J&W HP-5MS column (30 m ×0.25 mmI.D., 0.25 μm film thickness, Agilent Technologies, Santa Clara, CA, USA). The flow rate of the carrier gas (Helium, 99.999 %) was 1.0 mL/min. The oven temperature was initially set at 45°C for 5 min, then increased to 320°C at a rate of 8°C/min, and kept at 320°C for 15 min before returning to the initial temperature, with a total cycle time of 54.36 min. The MS detector was operated in scan mode (mass range 45–300 m/z). MSD ChemStation (Agilent) was used for data acquisition and processing. Compound identifications were performed by comparing the experimental mass spectra to those contained in the National Institute of Standards and Technology database (NIST/EPA/NIHMass Spectral Library). The identity of the compound was confirmed only if a match quality score above 90 was achieved. Statistical analyses In the absence of specific standards, since the compounds actually present in the analyzed samples are not known a priori, semi-quantitative measurements were carried out using peak area values of the identified compounds, which are directly related to their concentration. Therefore, for selected VOCs, among all the compounds identified in the indoor environmental samples, a semi-quantitative evaluation was performed considering the peak area value and, finally, multivariate statistical data analysis (Principal Component Analysis) was performed by SIMCA® (Umetrics, Umea, Sweden). RESULTS AND DISCUSSION Optimization of SPME and chromatographic conditions Several polymers with different thicknesses and polarity are commercially available and currently used as SPME coatings according to the analyte and sample characteristics. In this study, five different SPME coatings (i.e., polydimethylsiloxane, divinylbenzene, carboxen, polyacrylate, and polyethylene glycol) were tested and compared in terms of extraction efficiency, evaluated by the number of detected peaks (signal-to-noise ratio > 3) and the total peak area of the VOCs profile in indoor air samples, used as a reference model, before starting the analysis of working environments inside the manufacturing plant. Then, two fibers (monophasic and biphasic, based on polydimethylsiloxane and carboxen/polydimethylsiloxane, respectively) were chosen and used for all subsequent analyses to recover the greatest number of compounds. Therefore, for each air sample, two parallel 30 min-SPME extraction processes with the two different fibers were carried out and the total list of the identified compounds was obtained by combining the results of each analysis. The SPME procedure was also optimized in terms of adsorption and desorption time, ranged from 10 -60 min and 3-9 min, respectively. Then, optimal values of 30 min (sampling/extraction time) and 6 min (desorption time) were applied for all analyses. The optimization of the temperature gradient was performed to achieve a good compromise between low chromatographic times and adequate peak resolution. Details of the employed analytical method are summarized in the experimental section, and, as an example, a typical VOC chromatographic profile is shown in Figure 1. VOC profiles The evaluation of indoor air quality was performed by a passive sampling process through SPME fiber exposure in different zones of the manufacturing factory. VOC measurements were conducted for three months during the summer, with a sampling frequency of fifteen days; the total number of sampling times is 6, for each SPME fiber, both when the system is on and when the system is off. The complete list of the compounds identified in the inner and outer chamber, at system on and off, is shown in Table S1 (Online Resource – Supplementary Information). A total of 212 compounds were identified: 146 and 52 in Zone A at system ON and OFF, and 105 and 37 in Zone B at system ON and OFF, respectively. As reported in Table 1, only 17 compounds were always present, both in Zone A and B, regardless of system conditions (ON or OFF). When the system was ON, 58 common compounds were observed both in Zone A and B (Table 2), while only 24 substances were concurrently found in both zones when the system was OFF (Table 3). Considering the Zone A, a compound comparison was performed between the system ON and OFF (Table 4). A total of 33 common compounds were found. Among them, higher levels of benzene and phenol-based molecules were observed when the system was ON. Similar evaluations were carried out about the data relating to the outer chamber (Table 5) at system on and off; fewer common compounds (i.e. 24) have been identified, at lower levels than those in the inner zone. A Venn diagram of the identified compounds, observed in specific conditions or common to the different situations, is shown in Figure 2. Among the 17 common compounds, identified in all cases (zone A and B and system ON and OFF), a semi-quantitative evaluation, shown in Figure 3, was performed for the potentially toxic compounds: benzene, (1-methyldodecyl)-, benzene, 1,3-dimethyl-, phenol, 4,4'-(1-methylethylidene)bis-, and p-xylene. Considering that the working conditions are different inside and outside the painting chamber when the system is on or off, multivariate analyses (i.e., Principal Component Analyses) were carried out to gain insight into these differences. The peak area values of a shortlist of 17 selected (presumably toxic) compounds such as benzene, xylene, and phenol derivatives, specifically: benzene, (1-butylnonyl)-; benzene, (1-ethylundecyl)-; benzene, (1-methyldodecyl)-; benzene, (1-methyltridecyl)-; benzene, (1-methylundecyl)-; benzene, (1-pentyloctyl)-; benzene, (1-propyldecyl)-; benzene, 1,2,3-trimethyl-; benzene, 1,3,5-trimethyl-; benzene, 1,3-dimethyl-; benzenesulfonamide, N-butyl-; o-xylene; phenol; phenol, 2,4'-isopropylidenedi-; phenol, 4,4'-(1-methylethylidene)bis-; p-xylene; toluene) were determined and used for the statistical analysis. In the data matrix, empty gaps, corresponding to missing data for VOCs not found in some of the samples examined have been filled with a virtual peak area value equal to the LOD signal, estimated as the tenth part of the minimum peak area within the entire data set. After data pre-treatment (centering and normalization), the PCA model showed two principal components; the PC1 axis justifies 82% of the total variance, while PC2 covers a further 17%. Each variable positively affects the regression parameters of the PCA model (R 2 = 0.99 and Q 2 0.99), and no outliers were found, as confirmed by the DModX plot (i.e., the Distance to the Model, measuring how well each observation fits the model). From the biplot of Figure 4, it is possible to observe a dense distribution of all the compounds investigated in the region corresponding to the switched-on plant, along the outer edge. Indeed, as expected, the observations ON fall in the region occupied by a high number of variables, and, specifically, the Biplot region occupied by A and B OFF does not contain any compounds. From the data in the correlation matrix, reported in Table S2 (Online Resource – Supplementary Information) Pearson coefficients higher than 0.90 were obtained for almost all compounds belonging to the class of benzene derivatives, except for the following three couples: benzene, (1-butylnonyl)-/benzene, 1,2,3-trimethyl-, benzene, (1-methylundecyl)-/benzene, 1,2,3-trimethyl-, and p-xylene/benzene, 1,2,3-trimethyl-. With the exception of two couples of compounds (phenol/benzene, 1,2,3-trimethyl- and o-xylene/benzene, 1,2,3-trimethyl-) with negative Pearson coefficients, positive correlations between the two areas throughout the operating phases ON/OFF were observed for all other compounds, suggesting that the VOCs in the internal and external chambers shared same sources (volatilization of paint solvents, personal care products, building materials, etc.) and underwent similar processes, showing comparable chemical lifetimes in the atmosphere. The proposed experimental plan did not allow a quantitative analysis of each VOC found in the environment, but it could detect the presence of these substances at very low levels (ppb or ppt), Specifically, within the scope of this study, only a semi-quantitative comparison of the levels of some selected volatile organic compounds in different working areas and stages was carried out. The results indicate, as expected, that when the manufacturing system is active, the relative amounts of organic compounds in the environment increase. Anyway, it can be assumed that the values obtained do not differ from the levels generally observed in urban areas, both residential and industrial sites. Numerous studies have reported exposure to air pollutants and often refer to single cities, short time periods, and specific air pollutants (Fassò et al. 2023; Gilardi et al. 2023). In particular, the phenomena of air pollution from benzene-based molecules (benzene is a ubiquitous pollutant of indoor and outdoor air, as well as class 1 carcinogenic substance, according to IARC - International Agency for Research on Cancer) have been extensively described in the recent literature, referring to various regions of Italy (Martellini et al. 2020; Toscano and Murena 2021; Cattaneo et al. 2021; Ielpo et al. 2021; Di Gilio et al. 2021; Cucciniello et al. 2022; Manco et al. 2022; Urbano et al. 2023). In addition to highly industrialized areas, high pollution levels are frequently reported in the most densely populated areas, in close correlation with geographic characteristics, climate, seasons, number of inhabitants, urban traffic, and time slots of the day (Battista et al. 2021; Badaloni et al. 2023; Ciacci et al. 2023). Therefore, in the complex air quality scenario, it is reasonable to assume that the levels of VOCs, found in indoor work environments, comply with occupational limits and air quality guidelines, considering the practices adopted by the company for continuous air exchange and all necessary measures for the health of workers, in full compliance with current legal provisions. Moreover, the effect of VOCs on indoor air quality and potential health consequences do not only depend on the concentration levels, but also on the exposure time which, generally, is limited to short periods of time for each worker, thanks to adequate work shifts. CONCLUSIONS In this work, an untargeted approach has been successfully applied to evaluate the exposure to volatile organic compounds in indoor work environments. More than two hundred volatile compounds have been identified by SPME and GC-MS, coupled with database searching. A semi-quantitative comparison of VOC levels in different areas and work stages was carried out, followed by multivariate analyses to explore differences in the VOC composition. As indoor air pollution has become a major health concern, the workplace monitoring by GC-MS fingerprinting, performed by the optimized workflow proposed in the present study, can be included within the consolidated approaches for the determination of air pollutants and the assessment of air quality in health assessment studies. Furthermore, although Italy, like every other European country, has adopted the European Legislative Decree 81/2008 to manage workplace safety, various commissions and research groups are working to update the legislation on indoor air quality; therefore, surveillance actions of internal environments and industrial emissions are continuously necessary.

The natural sources of VOCs are mainly the sea, vegetation, soil, volcanoes, and rainwater\u0026nbsp;(Huang et al. 2018). Many VOCs are chemicals produced and used by humans in the preparation of pharmaceuticals, paints, and refrigerants. Numerous studies have reported that VOCs may have short- and long-term harmful effects on human health and cause respiratory, neurological, and circulation diseases\u0026nbsp;(Kumar et al. 2018; Zhang et al. 2020). Furthermore, VOCs affect air quality and climate change as precursors of ground-level ozone and secondary organic aerosol\u0026nbsp;(Guo et al. 2017).\u003c/p\u003e\n\u003cp\u003eHumans typically spend most of their time inside buildings, and this has prompted many field studies\u0026nbsp;(Žitnik et al. 2010; Zhang and Zhu 2012). In closed environments, both residential and working, indoor air quality depends not only on building materials and furnishings\u0026nbsp;(Schieweck and Salthammer 2009; Schieweck 2021), but also on human presence, the activity of occupants and their cleaning and personal care products\u0026nbsp;(Tham 2016; Gonz\u0026aacute;lez-Mart\u0026iacute;n et al. 2021). Moreover, gases and/or particulates are also released from external sources, and all these aspects contribute to the overall VOC composition and air quality\u0026nbsp;(Schalm et al. 2022).\u003c/p\u003e\n\u003cp\u003eVOC fingerprints are usually evaluated by gas chromatography coupled mass spectrometry and for the sample extraction, SPME (Solid-Phase MicroExtraction) is one of the most used microextraction techniques for its ease of use and high extraction efficiency, in terms of the number and type of extracted compounds\u0026nbsp;(Lord and Pawliszyn 2000; Ner\u0026iacute;n et al. 2009). SPME is a solvent-free technique that combines extraction, concentration, and clean-up into a single step, without requiring chemical-physical treatments; it is not invasive, and it does not change the environmental conditions of the sample, allowing the study of VOC production in real conditions\u0026nbsp;(Ouyang and Pawliszyn 2006; Spadaccino et al. 2021).\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eIn this work, an untargeted approach is described for the characterization of VOCs in indoor working environments by SPME-GC-MS. The exposure to volatile organic compounds of workers in different areas of an engine manufacturing plant was evaluated at different stages of the working cycle. Several SPME fibers of different polarity and composition were used to extract the greatest number of compounds, identified by mass spectrometry analysis coupled with database searching. Finally, multivariate analyses were performed to explore similarities and differences in the VOC composition.\u0026nbsp;\u003c/p\u003e"},{"header":"MATERIALS AND METHODS","content":"\u003ch2\u003eSolid-Phase MicroExtraction (SPME) experimental conditions\u003c/h2\u003e\n\u003cp\u003eThe microextraction process was carried out using an SPME device (Supelco, JVA Analytical Ltd., Ireland). Two fibers with different polarity were used: 85 \u0026micro;m carboxen/polydimethylsiloxane (CAR/PDMS), and 100 \u0026micro;m polydimethylsiloxane (PDMS), purchased from Supelco/Sigma-Aldrich (Bellefonte, PA, USA). The fibers were thermally conditioned following the manufacturer\u0026rsquo;s recommendations before their first use. Each SPME fiber was exposed to the air for 30 min at room temperature in two different areas of the manufacturing factory: in the mixing painting chamber (that is where the painting of the engines is carried out, area A) and the engine painting area (the working area adjacent to the engine painting room, zone B). The sampling was carried out with the factory active and running (hereinafter referred to as system on) and with the factory switched off (system off).

The SPME device was directly inserted into the GC\u0026ndash;MS injection port; the injections were made in splitless mode using an SPME injection sleeve (0.75 mm I.D) with a desorption temperature and time of 250\u0026deg;C and 6 min, respectively. The\u0026nbsp;chromatographic separations were carried out using the analytical J\u0026amp;W HP-5MS column (30 m \u0026times;0.25 mmI.D., 0.25 \u0026mu;m film thickness, Agilent Technologies, Santa Clara, CA, USA). The flow rate of the carrier gas (Helium, 99.999 %) was 1.0 mL/min. The oven temperature was initially set at 45\u0026deg;C for 5 min, then increased to 320\u0026deg;C at a rate of 8\u0026deg;C/min, and kept at 320\u0026deg;C for 15 min before returning to the initial temperature, with a total cycle time of 54.36 min. The MS detector was operated in scan mode (mass range 45\u0026ndash;300 m/z). MSD ChemStation (Agilent) was used for data acquisition and processing. Compound identifications were\u0026nbsp;performed by comparing\u0026nbsp;the experimental mass spectra to those contained in the National Institute of Standards and Technology database (NIST/EPA/NIHMass Spectral Library). The identity of the compound was confirmed only if a match quality score above 90 was achieved.\u003c/p\u003e\n\u003ch2\u003eStatistical analyses\u003c/h2\u003e\n\u003cp\u003eIn the absence of specific standards, since the compounds actually present in the analyzed samples are not known a priori, semi-quantitative measurements were carried out using peak area values of the identified compounds, which are directly related to their concentration. Therefore, for selected VOCs, among all the compounds identified in the indoor environmental samples, a semi-quantitative evaluation was performed considering the peak area value and, finally, multivariate statistical data analysis (Principal Component Analysis) was performed by SIMCA\u0026reg; (Umetrics, Umea, Sweden).\u003c/p\u003e"},{"header":"RESULTS AND DISCUSSION","content":"\u003ch2\u003eOptimization of SPME and chromatographic conditions\u003c/h2\u003e\n\u003cp\u003eSeveral polymers with different thicknesses and polarity are commercially available and currently used as SPME coatings according to the analyte and sample characteristics. In this study, five different SPME coatings (i.e., polydimethylsiloxane, divinylbenzene, carboxen, polyacrylate, and polyethylene glycol) were tested and compared in terms of extraction efficiency, evaluated by the number of detected peaks (signal-to-noise ratio \u0026gt; 3) and the total peak area of the VOCs profile in indoor air samples, used as a reference model, before starting the analysis of working environments inside the manufacturing plant. Then, two fibers (monophasic and biphasic, based on polydimethylsiloxane and carboxen/polydimethylsiloxane, respectively)\u0026nbsp;were chosen and used for all subsequent analyses to recover the greatest number of compounds. Therefore, for each air sample, two parallel 30 min-SPME extraction processes with the two different fibers were carried out and the total list of the identified compounds was obtained by combining the results of each\u0026nbsp;analysis. The SPME procedure was also optimized in terms of adsorption and desorption time, ranged from 10 -60 min and 3-9 min, respectively. Then, optimal values of 30 min (sampling/extraction time) and 6 min (desorption time) were applied for all analyses.\u003c/p\u003e\n\u003cp\u003eThe optimization of the temperature gradient was performed to achieve a good compromise between low chromatographic times and adequate peak resolution. Details of the employed analytical method are summarized in the experimental section, and, as an example, a typical VOC chromatographic profile is shown in Figure 1.\u003c/p\u003e\n\u003ch2\u003eVOC profiles\u003c/h2\u003e\n\u003cp\u003eThe evaluation of indoor air quality was performed by a passive sampling process through SPME fiber exposure in different zones of the manufacturing factory.\u0026nbsp;VOC measurements were conducted for three months during the\u0026nbsp;summer, with a sampling frequency of fifteen days; the total number of sampling times is 6, for each SPME fiber, both when the system is on and when the system is off.\u0026nbsp;The complete list of the compounds identified in the inner and outer chamber, at system on and off, is shown in Table S1 (Online Resource \u0026ndash; Supplementary Information). A total of 212 compounds were identified: 146 and 52 in Zone A at system ON and OFF, and 105 and 37 in Zone B at system ON and OFF, respectively.\u003c/p\u003e\n\u003cp\u003eAs reported in Table 1, only 17 compounds were always present, both in Zone A and B, regardless of system conditions (ON or OFF). When the system was ON, 58 common compounds were observed both in Zone A and B (Table 2), while only 24 substances were concurrently found in both zones when the system was OFF (Table 3). Considering the Zone A, a compound comparison was performed between the system ON and OFF (Table 4). A total of 33 common compounds were found. Among them, higher levels of benzene and phenol-based molecules were observed when the system was ON. Similar evaluations were carried out about the data relating to the outer chamber (Table 5) at system on and off; fewer common compounds (i.e. 24) have been identified, at lower levels than those in the inner zone.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eA Venn diagram of the identified compounds, observed in specific conditions or common to the different situations, is shown in Figure 2. Among the 17 common compounds, identified in all cases (zone A and B and system ON and OFF), a semi-quantitative evaluation, shown in Figure 3, was performed for the potentially toxic compounds: benzene, (1-methyldodecyl)-, benzene, 1,3-dimethyl-, phenol, 4,4\u0026apos;-(1-methylethylidene)bis-, and p-xylene.\u003c/p\u003e\n\u003cp\u003eConsidering that the working conditions are different inside and outside the painting chamber when the system is on or off, multivariate analyses (i.e., Principal Component Analyses) were carried out to gain insight into these differences. The peak area values of a shortlist of 17 selected (presumably toxic) compounds such as benzene, xylene, and phenol derivatives, specifically: benzene, (1-butylnonyl)-; benzene, (1-ethylundecyl)-; benzene, (1-methyldodecyl)-; benzene, (1-methyltridecyl)-; benzene, (1-methylundecyl)-; benzene, (1-pentyloctyl)-; benzene, (1-propyldecyl)-; benzene, 1,2,3-trimethyl-; benzene, 1,3,5-trimethyl-; benzene, 1,3-dimethyl-; benzenesulfonamide, N-butyl-; o-xylene; phenol; phenol, 2,4\u0026apos;-isopropylidenedi-; phenol, 4,4\u0026apos;-(1-methylethylidene)bis-; p-xylene; toluene) were determined and used for the statistical analysis. In the data matrix, empty gaps, corresponding to missing data for VOCs not found in some of the samples examined have been filled with a virtual peak area value equal to the LOD signal, estimated as the tenth part of the minimum peak area within the entire data set. After data pre-treatment (centering and normalization), the PCA model showed two principal components; the PC1 axis\u0026nbsp;justifies 82% of the total variance, while PC2 covers a further 17%.\u0026nbsp;Each variable positively affects the regression parameters of the PCA model (R\u003csup\u003e2\u003c/sup\u003e= 0.99 and Q\u003csup\u003e2\u003c/sup\u003e 0.99), and no outliers were found, as confirmed by the DModX plot (i.e., the Distance to the Model, measuring how well each observation fits the model). From the biplot of Figure 4, it is possible to observe a dense distribution of all the compounds investigated in the region corresponding to the switched-on plant, along the outer edge. Indeed, as expected, the observations ON fall in the region occupied by a high number of variables, and, specifically, the Biplot region\u0026nbsp;occupied by A and B OFF does not contain any compounds.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eFrom the data in the correlation matrix, reported in Table S2 (Online Resource \u0026ndash; Supplementary Information) Pearson coefficients\u0026nbsp;higher than 0.90\u0026nbsp;were obtained for almost all compounds belonging to the class of benzene derivatives, except for the following three couples:\u0026nbsp;benzene, (1-butylnonyl)-/benzene, 1,2,3-trimethyl-, benzene, (1-methylundecyl)-/benzene, 1,2,3-trimethyl-, and p-xylene/benzene, 1,2,3-trimethyl-. With the exception of two couples of compounds (phenol/benzene, 1,2,3-trimethyl- and o-xylene/benzene, 1,2,3-trimethyl-) with negative\u0026nbsp;Pearson coefficients, positive correlations between the two areas throughout the operating phases ON/OFF were observed for all other compounds, suggesting that the VOCs in the internal and external chambers shared same sources (volatilization of paint solvents, personal care products, building materials, etc.) and\u0026nbsp;underwent similar processes, showing comparable chemical lifetimes in the atmosphere.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eThe proposed experimental plan did not allow a quantitative analysis of each VOC found in the environment, but it could detect the presence of these substances at very low levels (ppb or ppt), Specifically, within the scope of this study, only a semi-quantitative comparison of the levels of some selected volatile organic compounds in different working areas and stages was carried out. The results indicate, as expected, that when the manufacturing system is active, the relative amounts of organic compounds in the environment increase. Anyway, it can be assumed that the values obtained do not differ from the levels generally observed in urban areas, both residential and industrial sites. Numerous studies have reported exposure to air pollutants and often refer to single cities, short time periods, and specific air pollutants (Fass\u0026ograve; et al. 2023; Gilardi et al. 2023). In particular, the phenomena of air pollution from benzene-based molecules (benzene is a ubiquitous pollutant of indoor and outdoor air, as well as class 1 carcinogenic substance, according to IARC - International Agency for Research on Cancer) have been extensively described in the recent literature, referring to various regions of Italy (Martellini et al. 2020; Toscano and Murena 2021; Cattaneo et al. 2021; Ielpo et al. 2021; Di Gilio et al. 2021; Cucciniello et al. 2022; Manco et al. 2022; Urbano et al. 2023). In addition to highly industrialized areas, high pollution levels are frequently reported in the most densely populated areas, in close correlation with geographic characteristics, climate, seasons, number of inhabitants, urban traffic, and time slots of the day (Battista et al. 2021; Badaloni et al. 2023; Ciacci et al. 2023). Therefore, in the complex air quality scenario, it is reasonable to assume that the levels of VOCs, found in indoor work environments, comply with occupational limits and air quality guidelines, considering the practices adopted by the company for continuous air exchange and all necessary measures for the health of workers, in full compliance with current legal provisions. Moreover, the effect of VOCs on indoor air quality and potential health consequences do not only depend on the concentration levels, but also on the exposure time which, generally, is limited to short periods of time for each worker, thanks to adequate work shifts.\u003c/p\u003e"},{"header":"CONCLUSIONS","content":"\u003cp\u003eIn this work, an untargeted approach has been successfully applied to evaluate the exposure to volatile organic compounds in indoor work environments.

and rapidly spread from the atmosphere to different environments. A large group of VOCs has been included in the class of air pollutants, therefore, their determination and monitoring using reliable and sensitive analytical methods represents a key aspect of health risk assessment. In this work, an untargeted approach is proposed for the evaluation of the exposure to volatile organic compounds of workers in an engine manufacturing plant by GC-MS measurements, coupled with Solid-Phase Microextraction (SPME). The analytical procedure was optimized in terms of SPME fiber, adsorption time, desorption time, and temperature gradient of the chromatographic run. For the microextraction of VOCs, the SPME fibers were exposed to the air in two different zones of the manufacturing factory, i.e., in the mixing painting chamber and the engine painting area. Moreover, the sampling was carried out with the painting system active and running (system on) and with the painting system switched off (system off). Overall, 212 compounds were identified, but only 17 were always present in both zones (mixing painting chamber and engine painting area), regardless of system conditions (on or off). Finally, a semi-quantitative evaluation was performed considering the peak area value of the potentially most toxic compounds by multivariate data analyses.","manuscriptTitle":"Determination of Volatile Organic Compounds (VOCs) in indoor work environments by Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-05-14 06:21:11","doi":"10.21203/rs.3.rs-4306126/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Major Revision","date":"2024-07-13T07:57:19+00:00","index":"","fulltext":""},{"type":"reviewerAgreed","content":"","date":"2024-05-10T05:21:43+00:00","index":0,"fulltext":""},{"type":"reviewersInvited","content":"","date":"2024-05-07T14:01:12+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"Environmental Science and Pollution Research","date":"2024-05-07T13:20:50+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2024-04-24T04:28:46+00:00","index":"","fulltext":""},{"type":"submitted","content":"Environmental Science and Pollution Research","date":"2024-04-22T09:16:54+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"environmental-science-and-pollution-research","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"espr","sideBox":"Learn more about [Environmental Science and Pollution Research](https://www.springer.com/journal/11356)","snPcode":"11356","submissionUrl":"https://submission.nature.com/new-submission/11356/3","title":"Environmental Science and Pollution Research","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"d26ba278-846d-4168-ab9f-44703cb55738","owner":[],"postedDate":"May 14th, 2024","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2024-08-26T16:04:52+00:00","versionOfRecord":{"articleIdentity":"rs-4306126","link":"https://doi.org/10.1007/s11356-024-34715-7","journal":{"identity":"environmental-science-and-pollution-research","isVorOnly":false,"title":"Environmental Science and Pollution Research"},"publishedOn":"2024-08-19 15:57:56","publishedOnDateReadable":"August 19th, 2024"},"versionCreatedAt":"2024-05-14 06:21:11","video":"","vorDoi":"10.1007/s11356-024-34715-7","vorDoiUrl":"https://doi.org/10.1007/s11356-024-34715-7","workflowStages":[]},"version":"v1","identity":"rs-4306126","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-4306126","identity":"rs-4306126","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
