Elderly exposure to indoor air pollutants
Abstract The aim of this work was to characterize the indoor air quality in Elderly Care Centers (ECCs) in order to assess the elders' daily exposure to air pollutants. Ten ECCs hosting 384 elderly were selected in Lisbon and Loures. Firstly, a time-budget survey was created based on questionnaires applied in the studied sites. Results showed that in average elders spend 95% of their time indoors splitted between bedrooms and living-rooms. Therefore, a set of physical and chemical parameters were measured continuously during the occupancy period in these two indoor micro-environments and in the outdoor. Results showed that indoor was the main environment contributing for the elders' daily exposure living in ECCs. In the indoor, the principal micro-environment contributing for the elders' daily exposure varied between bedrooms and living-rooms depending not only on the characteristics of the ECCs but also on the pollutants. The concentrations of CO2, VOCt, O3 and PM10 exceeded the limit values predominantly due to the insufficient ventilation preconized in the studied sites.
Highlights Elderly spend 95% of their time indoors. Indoor is the main site contributing for the elders' exposure to air pollutants. Inadequate ventilation is a significant problem in Elderly Care Centers. Identification of the micro-environments with highest impacts on elderly exposure.
