“…[7][8][9] Though a small number of authors do not find any significant difference between diesel (B0) and pure biodiesel (B100) and there are others that have found smaller emissions for diesel than biodiesel. [10][11][12] On the other hand, studies about pollutant emissions reduction for oxidized biofuels or mixed ones are scarce.…”

“…9 In general, the emissions of BTEX decreased with the increase of biodiesel content in the diesel/biodiesel blend because aromatics are virtually absent in biofuel. However, some studies showed that the profiles of vehicle emissions of these pollutants are influenced by engine operation conditions (i.e., load, speed, and ignition temperature), quality and type of fuel.…”

This study evaluated the concentration profiles of regulated and unregulated pollutants emitted from a stationary diesel engine cycle, operating at the speed of 1800 rpm and 0% load, using biofuels and binary blends. The experimental test considered fuel burning time on three different periods and storage times. The operation of the engine when it is still cold, for example at 15 minutes, showed negative effect on particulate matter (PM), benzene and ethylbenzene emissions in pure soybean biodiesel (B100) compared to the blend of diesel with 5% biodiesel (B5). Regarding to the concentration of mono aromatics, aliphatic hydrocarbons and polycyclic aromatic hydrocarbons (PAH), this study showed similar results to those reported in the literature, where B5 fuel emits more pollutants than pure biodiesel. However, comparing some pollutants individually, benzene and ethylbenzene emissions were higher for B100 and pure soybean biodiesel with butil-hydroxyanisol additive (B100 Adt). The B5 showed the highest concentration profile for the PAH sum in the gaseous and particulate phases in longer engine operation periods.

“…To date, research on BD has mostly focused on the analysis of CE emission products of fuels derived from various production processes and manufacturing sources (Di et al, 2009;Tiyapongpattana et al, 2008). BD derived from soy-bean vegetable oil is largely composed of fatty acid derivatives (e.g., methyl linoleate; see Supplemental Material, Table S1), and its combustion products may include high levels of unsaturated aldehydes compared to neat D. The unsaturated sites, serving as major targets of lipid peroxidation, may result in formation of both oxidized and unsaturated aldehydes (Fullana et al, 2004;Da Silva and Pereira, 2008;Seaman et al, 2009).…”

Over the past decade, soy biodiesel (BD) has become a first alternative energy source that is economically viable and meets requirements of the Clean Air Act. Due to lower mass emissions and reduced hazardous compounds compared to diesel combustion emissions (CE), BD exposure is proposed to produce fewer adverse health effects. However, considering the broad use of BD and its blends in different industries, this assertion needs to be supported and validated by mechanistic and toxicological data. Here, adverse effects were compared in lungs and liver of BALB/cJ mice after inhalation exposure (0, 50, 150, or 500 μg/m 3 ; 4 h/d, 5 d/wk, for 4 wk) to CE from 100% biodiesel (B100) and diesel (D100). Compared to D100, B100 CE produced a significant accumulation of oxidatively modified proteins (carbonyls), an increase in 4-hydroxynonenal (4-HNE), a reduction of protein thiols, a depletion of antioxidant gluthatione (GSH), a dose-related rise in the levels of biomarkers of tissue damage (lactate dehydrogenase, LDH) in lungs, and inflammation (myeloperoxidase, MPO) in both lungs and liver. Significant differences in the levels of inflammatory cytokines interleukin (IL)-6, IL-10, IL-12p70, monocyte chemoattractant protein (MCP)-1, interferon (IFN) γ, and tumor necrosis factor (TNF)-α were detected in lungs and liver upon B100 and D100 CE exposures. Overall, the tissue damage, oxidative stress, inflammation, and cytokine response were more pronounced in mice exposed to Address correspondence to Dr. Anna A.

Epidemiologic and occupational studies demonstrated that ambient particular matter (PM) and diesel exhaust particles exert deleterious effects on human health, including exacerbation of preexisting lung disease, increased incidence of respiratory infections, decrement in lung capacity, and enhanced risk of lung cancer (Sawyer et al., 2010;LaGier et al., 2013). According to the U.S. Environmental Protection Agency (EPA), elevated levels of airborne PM, nitrogen oxides, and sulfur oxides contribute to serious health problems in the United States, producing increased acute respiratory symptoms, chronic bronchitis, and aggravation of asthma, cardiovascular diseases, and premature mortality (Ghio et al., 2012). The International Agency for Research on Cancer (IARC) recently identified diesel combustion emissions (CE) as a Group 1 human carcinogen after chronic exposure (Benbrahim-Tallaa et al., 2012). Diesel exhaust particles are mainly aggregates of spherical carbon particles coated with inorganic and organic substances. The inorganic fraction primarily consists of small solid carbon (or elemental carbon) PM ranging from 0.01 to 0.08 microns in diameter. The organic fraction is composed of organic compounds such as aldehydes, alkanes and alkenes, and high-molecular-weight polycyclic aromatic hydrocarbons (PAH) and PAH derivatives, such as nitro-PA...

“…With further increase in the oxygen content for B50 and B100, the BSFC increases significantly (42% and 34.4% for 800 rpm and 1200 rpm, respectively). This is mainly attributed to the decrease in the lower heating value of biodiesel as suggested by most of the researchers [6,7,8]. Another reason may due to the high viscosity of biodiesel.…”
