“…(Teixeira et al 2010). As described above, in this region the alcohol fleet corresponds to only 4%, and besides that, according to some authors (Allen et al 2008, Abrantes et al 2009), the emission of PAHs from the use of hydrated alcohol is very low and almost negligible when compared to gasoline emissions. In order to characterize the major sources of PAH emission, the study of ratios was applied (Tsapakis et al 2002, Vasconcellos et al 2003.…”

“…In the MAPA the alcohol fleet corresponds to only 4% (Teixeira et al 2010), ESTIMATED ATMOSPHERIC EMISSIONS FROM BIODIESEL and besides that, according to some authors (Allen et al 2008), the emission of PAHs, from the use of hydrated alcohol, is almost negligible compared to gasoline. Other authors (Abrantes et al 2009) reported that the emission of PAHs ethanol from vehicles were on average 92% lower than PAHs emission from the gasohol vehicle. Figure 6 shows the seasonal average concentration of PAHs in the MAPA.…”

The purpose of the present study was to estimate emissions of some pollutants (CO, NO X , HC, SO X , and PM) in diesel fleet due to the addition of biodiesel in different blends, as well as to assess atmospheric pollutant concentrations in the metropolitan area of Porto Alegre (MAPA). The methodology was based on inventories from mobile sources based on US EPA's technical report. Regarding air quality the following parameters were determined: PM 10 , PM 2.5 , CO, NO X , O 3 , SO 2 , HC and PAHs. The results showed a decrease for emissions PM, CO, and HC, and a slight increase for NO X . The characterization of atmospheric pollutants in the metropolitan area of Porto Alegre showed that they are influenced by mobile sources, particularly diesel vehicles. The diagnosis of ratios analysis that was applied to facilitate the identification of sources of PAHs, indicated an influence of diesel oil.

“…A main contributor to PAH concentrations in road dust as well as urban areas is vehicle exhaust. Abrantes et al (2009) reported that total emissions and toxicities of PAHs released from light-duty vehicles using ethanol fuel are less than those using gasohol. For example, in ethanol vehicles, total EFs of PAHs ranged from 11.7 to 27.4 µg/km.…”

“…9 From the total PAH analyzed (83.5 ng m −3 in winter and 574 ng m −3 in summer), LM-PAHs corresponded to 93%. Abrantes et al 17 investigated emissions from vehicular engines using a chassis dynamometer powered with gasoline and anhydrous ethanol. The results presented as emission rate showed that lighter PAHs were prevalent, while larger molar mass PAHs were not detected.…”

In order to study the emission of vapor-phase polycyclic aromatic hydrocarbons (PAHs) by light-duty vehicles burning gasoline and ethanol blends, air samplings were performed at a parking lot in Londrina, PR, Brazil. The samples were obtained during the summer and winter 2012. The semi-volatile PAHs were collected using a cartridge packed with XAD-2 resin, extracted under sonication and subsequently analyzed by liquid chromatograph equipped with fluorescence and photodiode array detectors. Acenapthene (ACE) appears as the most abundant PAH, followed by acenapthylene (ACY) (summer) and fluorene (FLU) (winter). From the total PAHs analyzed (83.5 ng m −3 in winter and 574 ng m −3 in summer), low molecular weight PAHs (LM-PAHs) corresponded to 93%. The PAH source fingerprint identified in this study was obtained from local and identified sources, and the fluoranthene (FLT) / (FLT + pyrene (PYR)) and anthracene (ANT) / (ANT + phenanthrene (PHE)) ratios corresponding to 0.94 and 0.46, respectively, were characteristic of gasoline and ethanol blend emission.
