First long-term air quality assessment in Luanda, Angola: Performance evaluatio...
Silva, Alan Victor; Furst, Leonardo; Cipoli, Yago A.; Soares, Marlene J.S.; Leitão, Anabela G.A.; Feliciano, Manuel; Alves, Célia A.Low-cost air quality monitoring stations (LCMS), which integrate sensors for gases and particulate matter (PM), offer an economical solution for expanding monitoring networks. However, their reliability requires validation, particularly in rapidly urbanising regions with limited infrastructure. This study presents the first long-term, continuous, multi-pollutant air quality assessment in Luanda, Angola - where ...

Furst, Leonardo; Cipoli, Yago; Galindo, Nuria; Yubero, Eduardo; Viegas, Carla; Gomes, Bianca; Cervantes, Renata; Nunes, Teresa; Feliciano, ManuelIn this study, indoor air quality was assessed in a store belonging to one of Portugal's largest commercial retail groups. A variety of methodologies were used, including gravimetric analysis for particulate matter (PM), optical monitors for real-time PM measurements, gas sensors and analyzers for CO2 and other gaseous pollutants, diffusion tubes for VOCs, and passive deposition for microorganisms. The average ...

Furst, Leonardo; Cipoli, Yago; Yubero, Eduardo; Galindo, Nuria; Viegas, Carla; Dias, Marta; Nunes, Teresa; Igrejas, Getúlio; Feliciano, ManuelThis paper provides a comprehensive assessment of indoor and outdoor air quality within a home improvement and gardening store chain in northeastern Portugal. In December 2021 and January 2022, two multipollutant systems were installed in the store and outdoors to assess air quality. Continuous monitoring included particulate matter below 10 µm (PM10), CO2, and comfort parameters. PM10 samples were collected us...

PM10-bound elements in Luanda's urban atmosphere: Concentrations, sources, and ...
Alves, Célia A.; Campa, Ana Sanchez de la; Cipoli, Yago; Furst, Leonardo; Higawa, Gustavo; Leitão, Anabela; Silva, Alan Victor; Feliciano, ManuelAn unprecedented study was carried out in the megacity of Luanda, Angola, involving daily sampling of particulate matter (PM10) from June to November 2023. The analysis was focused on the detection of 56 metal(loid)s and complemented by the application of several contamination and health risk indices. PM10 levels ranged from 23.6 to 108 μg/m3, averaging 59.3 μg/m3, exceeding WHO’s 24-h guideline on 83% of days....
School air quality and thermal comfort: a multi-pollutant seasonal assessment
Charres, Isabella; Furst, Leonardo; Furst, Leonardo; Vicente, Estela D.; Soares, Marlene; Viegas, Carla; Cervantes, Renata; Cerqueira, MárioAs evidence of children's vulnerability to air pollution grows, research on school air quality has increased significantly in the 21st century. Given the complex factors influencing indoor and outdoor air quality in schools, each study offers valuable insights. This study contributes by assessing particulate matter, gaseous pollutants, thermal comfort and microorganisms in a large school encompassing different ...

Charres, Isabella; Lucarelli, Franco; Feliciano, Manuel; Furst, Leonardo; Alves, CéliaFive-stage Sioutas impactors were used to collect particulate matter (PM) in 4 classrooms and the playground of a school with various educational levels near the largest industrial chemical complex in Portugal. Monitoring was carried out over a total period of 8 weeks split equally between winter and spring. Samples were analysed for its elemental composition by PIXE. The prevalence of respiratory symptoms in s...
