Comprehensive assessment of PM10 from home heating using different appliances a...
Cipoli, Yago Alonso; Vicente, Estela D.; Charres, Isabella; Evtyugina, Margarita; Alfosea-Simón, Marina; Lucarelli, Franco; Kováts, Nora; Ryšavý, JiříThe European Union has implemented policies to promote renewable energy, with an emphasis on biomass for heat generation. However, residential biomass combustion is a major source of particulate matter (PM10), and its chemical constituents pose health concerns worldwide. This study characterised the organic and inorganic composition, oxidative potential (OP), and ecotoxicity of PM10 indoors and outdoors during ...
Chemical speciation and oxidative potential of PM10 in different residential mi...
Cipoli, Yago Alonso; Vicente, Estela D.; Evtyugina, Margarita; Figueiredo, Daniela R.; Pietrogrande, Maria C.; Lucarelli, Franco; Feliciano, ManuelExposure to particulate matter (PM) and its chemical constituents in residential microenvironments has become a major health concern worldwide. The oxidative potential (OP) has been proposed as a metric for estimating the PM capacity to induce oxidative stress and, consequently, health effects. In the present study, PM10 was daily monitored simultaneously in the bedroom, living room and kitchen of three dwellin...
PM2.5 chemical composition and health risks by inhalation near a chemical complex
Alves, Célia; Evtyugina, Margarita; Vicente, Estela; Vicente, Ana; Rienda, Ismael Casotti; Sánchez de la Campa, Ana; Tomé, Mário; Duarte, IolaParticulate matter (PM2.5) samples were collected in the vicinity of an industrial chemical pole and analysed for organic and elemental carbon (OC and EC), 47 trace elements and around 150 organic constituents. On average, OC and EC accounted for 25.2% and 11.4% of the PM2.5 mass, respectively. Organic compounds comprised polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, anhydrosugars, phenolics, aromati...
Nighttime-daytime PM10 source apportionment and toxicity in a remoteness inland...
Cipoli, Yago Alonso; Alves, Célia; Rapuano, Marco; Evtyugina, Margarita; Rienda, Ismael Casotti; Kovats, Nora; Vicente, Ana; Giardi, FabioThe distribution of daytime and nighttime sources of PM10 collected from January to March 2021 at an urban background site in the city of Braganca, Portugal, was performed using positive matrix factorisation (PMF). Additional data of PM2.5, NOx and meteorological variables were collected to support the interpretations. A solution with 5 factor profiles was found: traffic (33%), dust (24%), biomass burning (21%)...

Emission factors for a biofuel impacted fleet in south America's largest metrop...
Pereira, Guilherme Martins; Kamigauti, Leonardo Yoshiaki; Nogueira, Thiago; Gavidia-Calderón, Mario Eduardo; Monteiro Dos Santos, DjacintoThe Metropolitan Area of São Paulo (MASP) is among the largest urban areas in the Southern Hemisphere. Vehicular emissions are of great concern in metropolitan areas and MASP is unique due to the use of biofuels on a large scale (sugar-cane ethanol and biodiesel). In this work, tunnel measurements were employed to assess vehicle emissions and to calculate emission factors (EFs) for heavy-duty and light-duty veh...
Outdoor charcoal grilling: particulate and gas-phase emissions, organic speciat...
Alves, Célia A.; Evtyugina, Margarita; Vicente, Estela; Vicente, Ana; Gonçalves, Cátia; Neto, Ana Isabel; Nunes, Teresa; Kováts, NoraCharbroiling is a major source of air pollution worldwide. In this study, the particulate and gas-phase emissions from the charcoal lighting phase and during the grilling of meat (pork and rump cap) and fish (sardine and salmon) on an outdoor barbecue grill were characterized. Some gaseous compounds (ethane, hexane, NO2, N2O, SO2, NH3, HCl) did not display significant variations between samples and the backgrou...
Organic profiles of brake wear particles
Alves, Célia; Evtyugina, Margarita; Vicente, Ana; Conca, Eleonora; Amato, FúlvioFour brake pads were tested in a bench dynamometer under test cycles with different braking severities: i) two types of conventional brake pads (low steel 1 and 2), and ii) two types of non-asbestos organic brake pads (NAO 1 and 2) with non-ferrous materials. Wear particles (PM10) were analysed for total carbon by a thermo-optical method and then solvent-extracted and analysed by gas chromatography–mass spectro...
Cooking activities in a domestic kitchen: chemical and toxicological profiling ...
Alves, Célia A.; Vicente, Estela D.; Evtyugina, Margarita; Vicente, Ana M. P.; Sainnokhoi, Tsend-Ayush; Kováts, NoraTo obtain emission factors and cooking-related chemical signatures, a monitoring campaign was carried out in a modern kitchen where different dishes of the Latin cuisine were prepared. Particulate matter (PM10, PM2.5 and PM1) and total volatile organic compounds (TVOCs) were continuously measured. Passive tubes for carbonyls and a high volume PM10 sampler were simultaneously used. PM10 filters were analysed for...
