“…The concentration of Cu shows an increase at 8.83 m down (the value reaches 75 mg/kg), where the silts are abundant, and another increase between 11.41 and 12.36 m. This increase is accompanied by an increase in the concentration of Cd and C org coinciding with a gravel zone with interstratifications of silts above the transition zone towards the base aquitard in S1UB (Figure 2). The origin of these metals could be mainly associated with the existence of the old gasoline pollution mentioned above, as they can be present in the composition of many gasolines, as indicated in Saint Pierre et al (2004). However, their presence together with their greater affinity for forming complexes with humic acids from the soil is not ruled out (Kerndorff and Schnizer, 1980 (Figure 3), a progressive increase below the water table in accordance with the stability fields of these two elements was observed (Krauskopt, 1979) as the alkalinity diminishes (although pH is never below 8).…”

“…These deliberately introduced metals include Al, Ca, Ce, Cr, Co, Cu, La, Pb, Li, Mg, Mn, Mo, Ni, Si, Ag, Na, Tl, Sn, W, V , Zn and Zr. [6][7][8] In previous studies, emissions of coarse particles were found to be dominated by the resuspension of dust and brake wear, while fine particles were mainly due to combustion processes. 9 The various trace metal sources in fine particulate matter emitted from road traffic were characterized in a road tunnel in Nice, France.…”

De janeiro a abril de 2009, amostras de partículas suspensas (TSP) e de materiais particulados (PM 10 e PM 2.5 ) foram coletadas de uma área urbana característica altamente impactada pelo tráfego de veículos. As concentrações de metais nestas amostras foram determinadas por ICP-OES (espectroscopia de emissão por plasma indutivamente acoplado). Ca, Mg, Fe e Al foram os metais mais abundantes presentes em TSP e PM 10 , com concentrações maiores que 427 ng m -3 . Em PM 2.5 , os metais mais abundantes foram Fe e Ca (307 e 60 ng m -3 , respectivamente), enquanto que as concentrações de Mg, Zn e Cu foram aproximadamente 20 ng m -3 . Para PM 10 e PM 2,5 , correlações elevadas foram obtidas para Ca, Mg e Al, enquanto a correlação de Ca e Mg com Fe mostrou-se pobre, indicando assim que Ca, Mg e Al provavelmente se originam principalmente da resuspensão de poeira, enquanto Fe pode ser também proveniente de uma fonte adicional, como o desgaste de freio. Elementos antropogênicos (Zn e Cu) tiveram fatores de correlação baixos, sugerindo fontes de emissões diferentes. A presença de Cu pode estar relacionada com o desgaste dos freios e a de Zn pode ser atribuída ao desgaste do pneu. Em partículas finas, Ca, Mn, Fe, Zn e Cu estavam presentes em razões mais elevadas do que em material da crosta. Uma vez que estas partículas são observadas principalmente devido aos processos de combustão, elas podem estar presentes na gasolina, óleo e lubrificantes. Fe foi correlacionado com Mn, enquanto fatores de correlação entre Ca e Mg foram relativamente baixos.From January to April 2009, samples of suspended particles (TSP) and particulate matters (PM 10 and PM 2.5 ) were collected from a well-characterized urban area that is highly impacted by vehicular traffic. The metal concentrations in these samples were determined using ICP-OES (inductively coupled plasma-optical emission spectroscopy). Ca, Mg, Fe and Al were the most abundant metals present in TSP and PM 10 , with concentrations higher than 427 ng m -3 . In PM 2.5 , the most abundant metals were Fe and Ca (307 and 60 ng m -3 , respectively), while the concentrations of Mg, Zn and Cu were approximately 20 ng m -3 . For PM 10 and PM 2.5 , high correlations were obtained for Ca, Mg and Al, while the correlation of Ca and Mg with Fe was poor, thereby indicating that Ca, Mg and Al probably originate mainly from the resuspension of dust, while Fe may also be originated from an additional source, such as brake wear. Anthropogenic elements (Zn and Cu) had low correlation factors, suggesting different emission sources. The presence of Cu may be linked to the abrasion of brakes, and Zn may be attributed to tire wear. In fine particles, Ca, Mn, Fe, Zn and Cu were present in higher ratios than in crustal material. Because these particles are mainly observed due to the combustion processes, they may be present in gasoline, oil and lubricants. Fe was correlated with Mn, while correlation factors between Ca and Mg were relatively lower.Keywords: total particulate matter, PM 10 , PM 2.5 , trace meta...

“…This fact corroborates with studies which claim metals in low concentration may reach the environment through combustion processes. 39 Regarding to B5, PM was rich in Ca, Na, and Zn. Among these metals, Ca and Zn were also abundant in the fuel.…”

“…Zn can be transferred during storage and transport and Cu is associated to the refining process. 39 The origin of other metals such as Al, Pb, and Mg may be related to engines and turbines wear. 40 Elements such as Al, Ca, Mn may be purposely added as additives to improve specific characteristics of the 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.
