In 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 ...

This 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 da; Feliciano, Manuel

An 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....

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, Manuel

Exposure 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...

The Composting of Water Hyacinth: A Life Cycle Assessment Perspective

Serafini, Lais Fabiana; Arrobas, Margarida; Rodrigues, Manuel Ângelo; Feliciano, Manuel; Miguens, Filomena; Oliveira, Verónica; Santos, Daniela

Water hyacinth is an invasive species that causes eutrophication in lentic waters. While mechanical removal is effective, it generates hazardous waste with biological contamination risk. Composting is a safe waste treatment option, inhibiting seeds and yielding agriculturally suitable compost. Life cycle assessment evaluated the environmental impacts of six composting piles using eight different by-products (po...

A Portable Measurement Device Based on Phenanthroline Complex for Iron Determin...

Fernandes, Samuel; Tlemçani, Mouhaydine; Bortoli, Daniele; Feliciano, Manuel; Lopes, Maria Elmina

: In this work, a newly developed self-contained, portable, and compact iron measurement system (IMS) based on spectroscopy absorption for determination of Fe2+ in water is presented. One of the main goals of the IMS is to operate the device in the field as opposed to instruments commonly used exclusively in the laboratory. In addition, the system has been tuned to quantify iron concentrations in accordance wit...

Indoor environmental quality is of utmost importance since urban populations spend much of their life in confined spaces. Supermarkets offer a wide range of products and services that are prone to emitting several air pollutants. This study aimed to comprehensively characterize indoor and outdoor air quality in a multinational supermarket, encompassing not only criteria parameters but also unregulated pollutant...

Ensuring good air quality is essential for safeguarding human health, requiring monitoring to comprehend air composition and formulate effective interventions. This study focused on indoor and outdoor air quality monitoring within a home improvement and gardening franchise store in northeastern Portugal. Real-time optical monitors recorded levels of particulate matter below 10 µm (PM10), while PM10 gravimetric ...
