One of the most widely available technologies to clean air in homes particulate matter less than 2.5 µm diameter (PM2.5), known have negative health impacts, are portable home purifiers (HAPs). This paper presents research which (1) explored effectiveness HAPs real-world conditions 57 three European cities; (2) examined if affect users’ perceptions indoor quality (IAQ) at home; and (3) consider...

Purpose A building's Indoor Air Quality (IAQ) has a direct impact on the health and productivity its occupants. Understanding effects of IAQ in educational buildings is essential both design construction phases for decision-makers. The purpose this paper to outline air quality occupants' performance, especially teachers students settings. Design/methodology/approach This study aims evaluate tea...

Activated carbon (AC) has been widely used in indoor air quality (IAQ) control for removal of hazardous volatile organic compounds (VOCs). A detrimental effect of this adsorption technology is that bacteria multiplied on AC may deteriorate IAQ. In this paper, antibacterial AC nanocomposites with welldispersed silver nanoparticles (Ag/ACs) were prepared by the attachment of Agþ on the functional...

The literature proves an evident association between indoor radon exposure and lung cancer, even at low doses. This study brings a new approach to the study of children's exposure to radon by aiming to evaluate exposure to indoor radon concentrations in nursery and primary schools from two districts in Portugal (Porto and Bragança), considering different influencing factors (occupation patterns...

Abstract During the pandemic of Covid-19, ventilation rate buildings and especially in spaces with high occupancy like classrooms, presents research interest. The strategies, combined use masks, contribute to decrease infection risk Covid-19. Also, improves Indoor Air Quality (IAQ), contributing good health users potentially influences their thermal comfort. In proposed work, experimental inves...

Humans spend more than 80% of their lives indoors resulting in an increased demand for high indoor air quality (IAQ). At the same time, tends to be at least twice as polluted outdoor air, and health threats caused by long-term exposure pollution are rising. Few experiments under real-life conditions have demonstrated positive effects plants on parameters related IAQ, improved humidity temperatu...
