“…Zhang et al (2009) found that sulfate and nitrate had higher emission rates for B20 (20% biodiesel and 80% diesel) than those for pure diesel. However, different results were observed by Wall et al (1987), which reported that lowering fuel sulfur content could reduce emissions for both sulfur dioxide and particulate sulfate. Thus, sulfate levels and mainly nitrate concentrations from PM found in this work could be attributed to the presence of biodiesel to diesel fuel (B3), which can emit higher NO x concentrations when compared to diesel emission (Chung et al 2008;Cheung et al 2009).…”

In this study, particulate matter (PM) were characterized from a place impacted by heavy-duty vehicles (Bus Station) fuelled with diesel/biodiesel fuel blend (B3) in the city of Londrina, Brazil. Sixteen priority polycyclic aromatic hydrocarbons (PAH) concentrations were analyzed in the samples by their association with atmospheric PM, mass size distributions and major ions (fluorite, chloride, bromide, nitrate, phosphate, sulfate, nitrite, oxalate; fumarate, formate, succinate and acetate; lithium, sodium, potassium, magnesium, calcium and ammonium). Results indicate that major ions represented 21.2% particulate matter mass. Nitrate, sulfate, and ammonium, respectively, presented the highest concentration levels, indicating that biodiesel may also be a significant source for these ions, especially nitrate. Dibenzo[a,h]anthracene and indeno[1,2,3,-cd]pyrene were the main PAH found, and a higher fraction of PAH particles was found in diameters lower than 0.25 μm in Londrina bus station. The fine and ultrafine particles were dominant among the PM evaluated, suggesting that biodiesel decreases the total PAH emission. However, it does also increase the fraction of fine and ultrafine particles when compared to diesel.

“…The impact of sulfur and aromatics in the fuel on the exhaust emissions has been the subject of investigations (45,46). The impact of sulfur has been stressed particularly, since sulfur has been shown to contribute to the particulate emission because of sulfate formation in the exhaust.…”

This paper presents results from the characterization of vehicle exhaust that were obtained primarily within the Swedish Urban Air Project, "Tatortsprojektet." Exhaust emissions from both gasoline-and diesel-fueled vehicles have been investigated with respect to regulated pollutants (carbon monoxide [CO], hydrocarbon [HC], nitrogen oxides [NO ], and particulate), unregulated pollutants, and in bioassay tests (Ames test, TCDD receptor affinity tests). Unregulated pollutants present in both the particle-and the semi-volatile phases were characterized. Special interest was focused on the impact of fuel composition on heavy-duty diesel vehicle emissions. It was confirmed that there exists a quantifiable relationship between diesel-fuel variables of the fuel blends, the chemical composition of the emissions, and their biological effects. According to the results from the multivariate analysis, the most important fuel parameters are: polycyclic aromatic hydrocarbons (PAH) content, 90% distillation point, final boiling point, specific heat, aromatic content, density, and sulfur content. -Environ Health Perspect 102(Suppl 4): 13-23 (1994).

“…Modem on-highway diesel fiiel contains less than 0.05% sulfiir by mass, as opposed to previous diesel fuel which had 0.15 to 0.3% sulfur by mass. The impact of sulfiir content on diesel engine particulate emission reduaion has been demonstrated by several researchers [46,47,48,49,50].…”
