“…In accordance with the information reported above, Sousa et al [48] found significantly higher PM 10 levels in outdoor air than in indoor air. The impact of polluted outdoor air in IAQ is also highlighted by a strong correlation found between the concentration measured indoors and outdoors.…”

“…Moreover, the same authors identified ventilation, building pathologies, construction characteristics (such as insulation and flooring), and the existence of a building adaption to the use as elderly care center as putative contributors to PM 2.5 , justifying the observation of higher levels of fine particles indoors than outdoors. Nevertheless, other studies have demonstrated that the ambient air is the main contributor to the PM 2.5 concentrations found indoors, due to observation of indoor-to-outdoor (I/O) concentration ratios below the unit [47,48]. In agreement, the existence of statistically significant correlations between the levels measured inside elderly centers and the levels assessed in their respective surrounding outdoor environments has also been reported [47,48].…”

“…Some of the existing studies aimed at evaluating the indoor PM 2.5 concentrations in elderly centers reported levels that exceeded the current WHO limit value (15 µg•m −3 ) in some of the audited facilities [2,9,18,45,46]. However, there are also works that found levels of PM 2.5 in elderly centers in compliance with the current WHO guideline, showing that healthy levels can be achieved in these environments [38,47,48]. In terms of the different indoor spaces evaluated within elderly center buildings, living rooms, and drawing rooms have been described as indoor spaces with particularly higher PM 2.5 concentrations [2,9].…”

Indoor Air Quality in Elderly Centers: Pollutants Emission and Health Effects

The world population is ageing, in particular in the developed world, with a significant increase in the percentage of people above 60 years old. They represent a segment of the population that is more vulnerable to adverse environmental conditions. Among them, indoor air quality is one of the most relevant, as elders spend comparatively more time indoors than younger generations. Furthermore, the recent COVID-19 pandemic contributed immensely to raising awareness of the importance of breathing air quality for human health and of the fact that indoor air is a vector for airborne infections and poisoning. Hence, this work reviews the state of the art regarding indoor air quality in elderly centers, considering the type of pollutants involved, their emission sources, and their health effects. Moreover, the influence of ventilation on air quality is also addressed. Notwithstanding the potential health problems with the corresponding costs and morbidity effects, only a few studies have considered explicitly indoor air quality and its impacts on elderly health. More studies are, therefore, necessary to objectively identify what are the impacts on the health of elderly people due to the quality of indoor air and how it can be improved, either by reducing the pollutants emission sources or by more adequate ventilation and thermal comfort strategies.

“…In addition, the relative contributions to their tidal volume regarding the rib cage and abdomen by the posture of children were essentially the same as that in adults [52]. Person gender and physical activity status determined the values of a tidal volume or VT (m 3 breathe -1 ) and the typical breath frequency or f (breath min -1 ) [53][54][55]. Therefore, the RDD values were calculated separately for the exposure of male and female students.…”

The health risk of schoolchildren who were exposed to airborne fine and ultrafine particles (PM0.1) during the COVID-19 pandemic in the Jambi City (a medium-sized city in Sumatra Island), Indonesia was examined. A questionnaire survey was used to collect information on schoolchildren from selected schools and involved information on personal profiles; living conditions; daily activities and health status. Size-segregated ambient particulate matter (PM) in school environments was collected over a period of 24 h on weekdays and the weekend. The personal exposure of PM of eight selected schoolchildren from five schools was evaluated for a 12-h period during the daytime using a personal air sampler for PM0.1 particles. The schoolchildren spent their time mostly indoors (~88%), while the remaining ~12% was spent in traveling and outdoor activities. The average exposure level was 1.5~7.6 times higher than the outdoor level and it was particularly high for the PM0.1 fraction (4.8~7.6 times). Cooking was shown to be a key parameter that explains such a large increase in the exposure level. The PM0.1 had the largest total respiratory deposition doses (RDDs), particularly during light exercise. The high level of PM0.1 exposure by indoor sources potentially associated with health risks was shown to be important.
