Mutagenicity of PM10-bound PAHs from non-exhaust sources
Vicente, Estela Domingos; Lopes, Isabel; Figueiredo, Daniela; Gonçalves, Cátia; Vicente, Ana; Alves, CéliaRoad trafc is a major source of airborne particles. While exhaust emissions have been deeply scrutinised, non-exhaust emissions deserved less attention despite their rising contribution to particle emissions from trafc. The mutagenicity of particulate matter (PM10) samples from wear between pavements and tyres and from road dust resuspension was determined by the Ames test with two Salmonella typhimurium strain...
Lung-deposited dose of particulate matter from residential exposure to smoke fr...
Vicente, Estela Domingos; Alves, Célia A.; Martins, Vânia; Almeida, Susana Marta; Lazaridis, MihalisResidential settings are of utmost importance for human exposure, as it is where people spend most of their time. Residential wood combustion is a widespread practice known as a source of indoor particulate matter (PM). Nevertheless, research on the risks of exposure associated with this source is scarce, and a better understanding of respiratory deposition of smoke particles is needed. The dosimetry model ExDo...
Characteristics of ash and particle emissions during bubbling fluidised bed com...
Ribeiro, João Peres; Vicente, Estela Domingos; Alves, Célia; Querol, Xavier; Amato, Fulvio; Tarelho, Luís A. C.Combustion of residual forest biomass (RFB) derived from eucalypt (Eucalyptus globulus), pine (Pinus pinaster) and golden wattle (Acacia longifolia) was evaluated in a pilot-scale bubbling fluidised bed reactor (BFBR). During the combustion experiments, monitoring of temperature, pressure and exhaust gas composition has been made. Ash samples were collected at several locations along the furnace and flue gas tr...
Effect of industrial and domestic ash from biomass combustion, and spent coffee...
Ribeiro, João Peres; Vicente, Estela Domingos; Gomes, Ana Paula; Nunes, Maria Isabel; Alves, Célia; Tarelho, Luís A. C.An experimental study was conducted at field conditions in order to evaluate the effect of application of ash from biomass combustion on some soil fertility characteristics and plant growth. Application of 7.5 Mg ha-1 industrial fly ash (IA), domestic ash (DA), and a 50:50 mix of domestic ash (DA) and spent coffee grounds (SCG) was made in different soil parcels. Lolium perenne seeds were sown and the grown bio...
