... In the last three decades, the Crude oil VOC Emissions (hereafter CVEs), have been investigated in literature either directly by means of laboratory and field-based analyses or indirectly via emission inventories (EIs) of the petroleum industry to regulate their contributions to the atmospheric pollutions (Table 1). However, only a few studies have focused on analysing the major mechanisms of CVEs and their influential parameters under different conditions such as water soluble fraction of HCs in crude oil contaminated soil (Saeed and Al-Mutairi, 2000;Saeed et al., 2013), ocean oil spillage (Afshar-Mohajer et al., 2018;Hanna and Drivas, 1993;Tonacci et al., 2015) and contaminated lands (Yang et al., 2007). The majority of these studies are associated with the fate of VOC emissions from petroleum industry in which VOCs emitted from various stages of crude oil processing including exploration, extraction, and production (Aklilu et al., 2018;DeLuchi, 1993;Helmig et al., 2014;Huang et al., 2018;Koss et al., 2017;Papailias and Mavroidis, 2018;Salih et al., 2018;Simpson et al., 2010;Villasenor et al., 2003;Wang et al., 2014;Warneke et al., 2014), storage (DeLuchi, 1993;Jackson, 2006;Khoramfar et al., 2018;Paulauskiene et al., 2009;Theophanides et al., 2007), transportation (de Vos et al., 2007;DeLuchi, 1993;Howard and Nikolas, 2001;Karbasian et al., 2017;Lee and Chang, 2014;Lee et al., 2013;Martens et al., 2001;Milazzo et al., 2017;Paulauskiene et al., 2008;Sani and Mohanty, 2009;Sani and Mohanty, 2008;Tamaddoni et al., 2014), refineries (Baltrėnas et al., 2011;Cetin et al., 2003;Lin and Lee, 2006;Lin et al., 2004;Liu et al., 2008;Pandya et al., 2006;Ragothaman and Anderson, 2017;Sonibare et al., 2007;Wei et al., 2014b;Wei et al., 2016;Zargar et al., 2013;Zhang Z. et al., 2017;Zhang et al., 2018), offshore (Afshar-Mohajer et al., 2019;Afshar-Mohajer et al., 2018;Bahreini et al., 2012;Han et al., 2007;Hanna and Drivas, 1993;Müller and Sedláčková, 2003;Saeed and Al-Mutairi, 2000;Saeed et al., 2013;Schädle et al., 2014;Tonacci et al., 2015;Uhler et al., 2010;Yagi et al., 2004;Yuan et al., 2014) and onshore activities (Almudhhi, 2016;Lawlor et al., 1997;Moyer et al., 1994;Müller and Sedláčková, 2003;Mustafa Salih et al., 2018;Soukup et al., 2007;Wang et al., 2015a;Wang et al., 2015b;Yang et al., 2007) as well as accidental spillages. ...
