“…The use of biodiesel has gained much attention by the fact it has been regarded to be more environmental friendly and less carbon and particulate matter emitter during its combustion. 16,[26][27][28][29][30][31][32] But, if by one hand biodiesel is pointed to emit less regulated pollutants, such as SO 2 , PM, CO, among others (except for NO x ), on the other hand, when non-regulated species are considered there is an opposite trend. For instance, when some unregulated pollutants are studied, such as O 3 , carbonyl compounds, polycyclic aromatic compounds (PAH), and size classified particulate matter, it was found biodiesel generally emit higher levels of them than mineral diesel.…”

“…For instance, when some unregulated pollutants are studied, such as O 3 , carbonyl compounds, polycyclic aromatic compounds (PAH), and size classified particulate matter, it was found biodiesel generally emit higher levels of them than mineral diesel. 8,[32][33][34][35][36] Indeed, Guarieiro et al 8 has also reported that the more biodiesel is added to fossil diesel, the higher levels of reactive oxygen species (ROS) are produced into particles then demonstrating biodiesel particles exhaustion would be more toxic, at least in relation to ROS, than mineral diesel. This would be likely to rise more human health-related problems.…”

In this study, it is reported the fractal dimension and morphology of ultrafine particles emitted by a diesel engine run with B4, B50, and B100. Transmission electron micrographs evidenced two main groups of particles with characteristic and distinct morphological behaviors: (i) particle agglomerate structures self-organized within a fractal-like geometry, and (ii) amorphous and irregular particles with diffuse edges in a liquid-like particle appearance, mainly associated with some sub-fractions of samples collected from B50 and B100 combustion. Particles from (i) showed typical diesel soot morphology and fractal dimension. Primary particle diameter (D pp) was 24 ± 4 nm, 23 ± 4 nm, and 20 ± 4 nm for B4, B50, and B100, respectively. Mean aggregate gyration diameters (D g) ranged from 242 ± 140 nm for B4, 210 ± 135 nm for B50, and to 232 ± 140 nm for B100. In turn, fractal dimensions (D f) were 1.94, 1.89, and 1.99 for B4, B50, and B100, respectively. On the other hand, particle from (ii) had their morphology impaired from the addition of biodiesel to petrodiesel in a way it did not follow a fractal geometry.

“…Production of diesel exhaust particles is accompanied by adsorption of organic and inorganic compounds from the combustion process and/or the adsorption of additional compounds. The chemical composition of PM of an aerodynamic diameter of 2.5 μm and less (PM2.5) from diesel exhaust consistently showed mainly elemental carbon (33–90%), organic carbon (7–49%), sulphates and nitrates (1–4%), metals and elements (1–5%) and a fraction of other chemicals (1–10%) .…”

Internal combustion engine emissions belong among the major anthropogenic sources of air pollution in urban areas. According to the International Agency for Research on Cancer, there is sufficient evidence of the carcinogenicity of diesel exhaust in human beings. Although alternative fuels, mainly biodiesel, have recently become popular, little is still known about the genotoxicity of emissions from these fuels. We analysed DNA damage expressed as the frequency of micronuclei (MN) in human bronchial epithelial cells (BEAS-2B), induced by extractable organic matter (EOM; tested concentrations: 1, 10 and 25 μg/ml) obtained from particle emissions from various blends of biodiesel with diesel fuels (including neat diesel fuel (B0), a blend of 70% B0 and 30% biodiesel (B30) and neat biodiesel (B100)). We also tested the effect of selected diesel exhaust organic/genotoxic components [benzo[a]pyrene (B[a]P) concentrations: 25, 100 and 200 μM; 1-nitropyrene (1-NP) concentrations: 1, 5 and 10 μM; 3-nitrobenzanthrone (3-NBA) concentrations: 1, 5 and 50 μM]. The cells were treated with the compounds for 28 and 48 hr. Our results showed that most of the tested compounds (except for the 25 μM B[a]P, 28-hr treatment) significantly increased MN frequency. The genotoxicity of EOMs from the engine emissions of diesel and biodiesel engines was comparable. Both nitro-PAH compounds demonstrated higher genotoxic potential in comparison with B[a]P. Considering our results and due to increasing popularity of alternative fuels, it is prudent that the potential genotoxic effects of various fuels are investigated across engine technologies and operating conditions in a relevant model system.
