“…Reduction of polycyclic aromatic hydrocarbons (PAHs) (Lin et al, 2017) and elemental carbon (EC) (Na et al, 2015) emissions were concomitantly observed. Many campaigns have been conducted over the past decade regarding the characterization of air quality degradation resulting from biodiesel/biofuel and diesel-fueled engine emissions (Dwivedi et al, 2006;Betha and Balasubramanian, 2011). Concentrations of volatile and soluble organics, which are indicators of toxicity and carcinogenicity, were found to be higher in biodiesel exhaust compared to diesel.…”

“…The growing concern about their environmental impact and health hazard in urban areas has resulted in the development of modern combustion engines that emit less particulate matter (PM). Concurrently, alternative fuels, such as vegetable oil-based biofuels (referred to as biodiesel), tend to be used in modern combustion engines (Agarwal, 2007;Giakoumis et al, 2012) in an attempt to further lessen soot particles emission and the concentration of unburned hydrocarbons (HC) and carbon monoxide (CO) released in engine exhausts (Dwivedi et al, 2006;Jung et al, 2006;Betha and Balasubramanian, 2011;Shah et al, 2014).…”

The growing concern about air quality and the impact exhaust particles can have on the environment has resulted in the increased use of alternative fuels. A sampling campaign from a conventional heavy diesel engine operated in typical transient cycle or steady-state condition, and running on diesel, 30% biodiesel in diesel, and 100% biodiesel was carried out. The particulate composition was characterized using Fourier Transform Infrared (FTIR) spectroscopy, Two-step Laser Mass Spectrometry (L2MS), Secondary Ion Mass Spectrometry (SIMS), thermo-optical analysis, and capillary electrophoresis. Elemental carbon is demonstrated to decrease from diesel to 100% biodiesel, in agreement with the evolution of aromatic bands and the MS abundance of C n -fragments, while organic carbon exhibits a constant level irrespective of the working regime. Aliphatic, aromatic, carboxyl, carbonyl, hydroxyl functionalities, and nitro compounds are found to depend on the engine-working regime. Mass spectra are mainly characterized by alkyl fragments (C n H 2n+1 + ), associated to normal and branched alkanes, PAHs and their alkylated derivatives. The addition of biodiesel to diesel changes the particulate composition towards more oxygenated constituents, such as carbonyl groups attributed to methyl ester CH 3 O + fragments of unburned biodiesel. Fuel-specific fragments have been identified, such as C 3 H 7 O + for diesel, and C 2 H 3 O 2 + and CH 3 O -for biodiesel. Nitrogenized compounds are revealed by -NO 2 functionalities and N-containing fragments. Principal Component Analysis (PCA) was successfully applied to discriminate the engine operating conditions, with a higher variance given by the fuel, thus allowing to better evaluate the environmental impacts of alternative energy source emissions.

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.
