Source apportionment of PM2.5 and PM10 by Ionic and Mass Balance (IMB) in a tra...
Pio, C.; Alves, C.; Nunes, T.; Cerqueira, M.; Lucarelli, F.; Nava, S.; Calzolai, G.; Gianelle, V.; Colombi, C.; Amato, F.; Karanasiou, A.; Querol, X.The recently developed Ion and Mass Balance (IMB) source apportionment methodology was applied to a traffic influenced urban aerosol, permitting the quantification of the contributions of 11 source components, or formation processes, which accounted for more than 96% of the measured aerosol mass loading. Main sources included exhaust and non-exhaust road vehicle emissions, biomass burning, secondary inorganic a...
Influence of operating conditions on chemical composition of particulate matter...
Vicente, E. D.; Duarte, M. A.; Calvo, A. I.; Nunes, T. F.; Tarelho, L. A. C.; Custódio, D.; Colombi, C.; Gianelle, V.; Sanchez de la Campa, A.Wood combustion experiments were carried out in a Portuguese woodstove to determine the effects of biofuel type, ignition technique, biomass load and cleavage, as well as secondary air supply, on the chemical composition of particles (PM10). Two typicalwood fuels in the Iberian Peninsulawere tested: pine (Pinus pinaster), a softwood, and beech (Fagus sylvatica), a hardwood. PM10 sampleswere analysed for organic...
Particulate and gaseous emissions from the combustion of different biofuels in ...
Vicente, E. D.; Duarte, M. A.; Tarelho, L. A. C.; Nunes, T. F.; Amato, F.; Querol, X.; Colombi, C.; Gianelle, V.; Alves, C. A.Seven fuels (four types of wood pellets and three agro-fuels) were tested in an automatic pellet stove (9.5 kWth) in order to determine emission factors (EFs) of gaseous compounds, such as carbon monoxide (CO), methane (CH4), formaldehyde (HCHO), and total organic carbon (TOC). Particulate matter (PM10) EFs and the corresponding chemical compositions for each fuel were also obtained. Samples were analysed for o...
