“…This value is associated with vehicle emissions, specifically gasoline [23,26]. Meanwhile the IP/BghiP (1.05) ratio indicated coal burning as a major source in this zone [27,28]. These results are congruent with the dimensions, anthropogenic activities and population density of the Cuernavaca city.…”

This study was carried out between January and February 2013, at two sites in the city of Cuernavaca, México, using low-volume equipment. Fifteen Polycyclic aromatic hydrocarbons (PAHs), were identified by gas chromatography coupled with mass spectrometry. The total average concentration observed for PAHs was 24.0 ng·m −3 , with the high molecular weight compounds being the most abundant. The estimated equivalent concentration for Benzo (a) P (BaPE) was 4.05 ng·m −3 . Diagnostic ratios together with the principal components analysis (PCA) allowed for establishing coal burning and vehicle OPEN ACCESSAtmosphere 2015, 6 1260 emissions as being the main sources of these compounds in the area. The PAHs used to calculate this index account for 51% of the 15 PAHs identified, which probably involves a risk to the exposed population.

“…In this study, the ratio of InP/(InP + BghiP) was between 0.34 and 1 with mean of 0.6 for PM 2.5 , 0.29 to 0.97 with 0.51 as average for PM 2.5-10 , indicating a mixed emission of engine exhaust and coal burning in winter [20]. c Grimmer et al [25]. d Feng et al [12].…”

“…In addition, the ratio of InP/(InP + BghiP) has been widely used to distinguish PAHs emission from traffic and coal burning. Ratios of 0.18, 0.37 and 0.56 were reported for gasoline vehicles, diesel vehicles and coal burning, respectively [12,13,25]. In this study, the ratio of InP/(InP + BghiP) was between 0.34 and 1 with mean of 0.6 for PM 2.5 , 0.29 to 0.97 with 0.51 as average for PM 2.5-10 , indicating a mixed emission of engine exhaust and coal burning in winter [20].…”

“…For examples, concentration ratios of indeno(1,2,3-cd)pyrene to benzo(ghi)perylene (IP/BghiP) are 0.2, 0.5 and 1.3 in the smokes from gasoline, diesel and coal combustions (Grimmer et al, 1983), whereas the ratios of benzo(ghi)perylene to benz(e)pyrene (BghiP/BeP) are 2.0 and 0.8 in the mobile exhausts and coal burning emissions, respectively (Grimmer et al, 1983;Ohura et al, 2004). As shown in Table 3, IP/BghiP and BghiP/BeP ratios in the urban, mountain and marine samples are close to those in coal burning smokes, suggesting that PAHs in the East Asia aerosols are largely derived from coal combustions, being consistent with the particulate PAHs compositions previously reported for 14 Chinese cities (Wang et al, 2006(Wang et al, , 2007.…”

Size-distributions of <i>n</i>-alkanes, PAHs and hopanes and their sources in the urban, mountain and marine atmospheres over East Asia

Abstract. Size-segregated (9 stages) n-alkanes, polycyclic aromatic hydrocarbons (PAHs) and hopanes in the urban (Baoji city in inland China), mountain (Mt. Tai in east coastal China) and marine (Okinawa Island, Japan) atmospheres over East Asia were studied using a GC/MS technique. Ambient concentrations of n-alkanes (1698±568 ng m −3 in winter and 487±145 ng m −3 in spring), PAHs (536±80 and 161±39 ng m −3 ), and hopanes (65±24 and 20±2.4 ng m −3 ) in the urban air are 1-2 orders of magnitude higher than those in the mountain aerosols and 2-3 orders of magnitude higher than those in the marine samples. Mass ratios of nalkanes, PAHs and hopanes clearly demonstrate coal-burning emissions as their major source. Size distributions of fossil fuel derived n-alkane, PAHs and hopanes were found to be unimodal in most cases, peaking at 0.7-1.1 µm size. In contrast, plant wax derived n-alkanes presented a bimodal distribution with two peaks at the sizes of 0.7-1.1 µm and >4.7 µm in the summer mountain and spring marine samples. Among the three types of samples, geometric mean diameter (GMD) of the organics in fine mode (<2.1 µm) was found to be smallest (av. 0.63 µm in spring) for the urban samples and largest (1.01 µm) for the marine samples, whereas the GMD in coarse mode (≥2.1 µm) was found to be smallest (3.48 µm) for the marine aerosols and largest (4.04 µm) for the urban aerosols. The fine mode GMDs of Correspondence to: G. Wang (wanggh@ieecas.cn) the urban and mountain samples were larger in winter than in spring and summer. Moreover, GMDs of 3-and 4-ring PAHs were larger than those of 5-and 6-ring PAHs in the three types of atmospheres. Such differences in GMDs can be interpreted by the repartitioning of organic compounds and the coagulation and hygroscopic growth of particles during a long-range transport from the inland continent to the marine area, as well as the difference in their sources among the three regions.
