“…Although the chemical composition of VOCs has varied widely in ambient atmosphere, aromatic (AR) hydrocarbons and halogenated hydrocarbons have often been emphasized in environmental studies due to their abundance and potential human health impacts (You et al, 2007;Matsumoto et al, 2010). Moreover, the important role of VOC in the photochemical reactions is well known, as they can exert influences on global climate change either directly or indirectly (e.g., photochemical ozone formation, acid rain, enhancement of the global greenhouse effect, and visibility reduction) (Dewulf and Langenhove, 1999;Lin et al, 2004;Chiang et al, 2007). In addition, a certain faction of them can also act as olfactive nuisance in environment (e.g., at landfill sites) (Termonia and Termonia, 1998).…”

To investigate the environmental behavior of volatile organic compounds (VOCs) in urban areas, their concentrations were measured at four urban monitoring sites (namely, N, S, E, and W) in Seoul, Korea (February to December 2009). A total of 27 compounds were quantified that consist of four chemical groups: aromatic (AR), halogenated aromatic, halogenated paraffin, and halogenated olefin. Results were evaluated by focusing on these four functional groups just mentioned and their summation term as total VOC (TVOC) along with several individual species (mainly AR species, that is, benzene, toluene, ethylbenzene, and xylene). The highest concentration of chemical groups was found from AR (71.1 -42.1 ppbC), while that for individual species confirmed the dominance of toluene (7.48 -3.88 ppb). The analysis of spatial distribution indicated that high TVOC levels were recorded at sites N and W, while it was not so significant such as S and E in terms of TVOC budget. Seasonal variation of these VOCs was characterized by the peak values in December to reflect the combined effects of pronounced source activities and meteorological conditions. Analysis of spatial variations in VOC levels between the four urban sites indicated that their distributions are tightly affected by local source processes in each area.

“…These studies found that vehicle emissions and solvent usage contributed most to the ambient VOCs in urban areas. A few studies were also conducted in industrial areas Wei et al, 2015;Shao et al, 2016) and petrochemical industrial regions with a lot of VOC emissions (Lin et al, 2004;Wei et al, 2015;Jia et al, 2016;Mo et al, 2017). These studies conducted in industrial areas found that the VOC sources and compositions are complex due to the different emissions and atmospheric processes (Warneke et al, 2014).…”

Abstract. Oil and natural gas are important for energy supply around the world. The exploring, drilling, transportation and processing in oil and gas regions can release a lot of volatile organic compounds (VOCs). To understand the VOC levels, compositions and sources in such regions, an oil and gas station in northwest China was chosen as the research site and 57 VOCs designated as the photochemical precursors were continuously measured for an entire year (September 2014-August 2015) using an online monitoring system. The average concentration of total VOCs was 297 ± 372 ppbv and the main contributor was alkanes, accounting for 87.5 % of the total VOCs. According to the propylene-equivalent concentration and maximum incremental reactivity methods, alkanes were identified as the most important VOC groups for the ozone formation potential. Positive matrix factorization (PMF) analysis showed that the annual average contributions from natural gas, fuel evaporation, combustion sources, oil refining processes and asphalt (anthropogenic and natural sources) to the total VOCs were 62.6 ± 3.04, 21.5 ± .99, 10.9 ± 1.57, 3.8 ± 0.50 and 1.3 ± 0.69 %, respectively. The five identified VOC sources exhibited various diurnal patterns due to their different emission patterns and the impact of meteorological parameters. Potential source contribution function (PSCF) and concentration-weighted trajectory (CWT) models based on backward trajectory analysis indicated that the five identified sources had similar geographic origins. Raster analysis based on CWT analysis indicated that the local emissions contributed 48.4-74.6 % to the total VOCs. Based on the high-resolution observation data, this study clearly described and analyzed the temporal variation in VOC emission characteristics at a typical oil and gas field, which exhibited different VOC levels, compositions and origins compared with those in urban and industrial areas.

“…Usually, the main VOCs in refinery exhaust were reported as propene, i-butane, benzene, n-butane, n-hexane, toluene, i-pentane, 1-butene,n-pentane, etc. (Cetin et al, 2003;Lin et al, 2004;Wei et al, 2014a). Only 1-butene was found abundant in this research, meaning possibly that the contribution of the refinery to VOCs in the sampling was limited.…”

ABSTRACT56 VOCs were monitored for a whole year in a refinery vicinity area in suburban of Jinan, as well as PM 2.5 , PM 10 , and ozone. The results of VOCs and particulate matters showed that January was the most polluted month during the sampling period, possibly resulting from coal burning in the district heating period of Jinan. According to the concentration profiles of monthly variety of the ambient pollutants, the change of VOCs showed a certain extent of positive correlation with PM 2.5 and PM 10 , while negative correlation with ozone. It was found that the average concentration of total VOCs was 50.58 µg m -3 while ethane and ethene were the most abundant VOC species with the concentrations of 24.58 and 3.94 µg m -3 , respectively. The high relative contribution of ethane was unusual, compared with the previous related VOC research in urban area of same city or other cities in China. Based on the analysis of the monitoring data, this area was not majorly affected by major VOCs pollutants from refinery emission. m & p-Xylene of 1.34 µg m -3 was the most abundant pollutant of BTEX. The BTEX ratio analysis presented that traffic exhaust was not the major VOCs source.
