“…Overall, levels of (ultra)fine particles at the two Portuguese preschools were similar in range to those reported for indoor air of schools in Greece (2.4 × 10 4 particles/cm 3 ; Diapouli et al, 2008), Italy (1.95-2.04 × 10 4 particles/cm 3 ; Buonanno et al, , 2013a, Spain (1.56 × 10 4 particles/cm 3 ; Reche et al, 2014;Rivas et al, 2014), South Korea (1.82 × 10 4 particles/cm 3 ; Kim et al, 2011), and Australia (1.21-1.69 × 10 4 particles/cm 3 ; Rumchev et al, 2007). In addition, a large ongoing epidemiological study of UFP in schools was conducted in Melbourne (Australia) .…”

“…Therefore, knowledge and understanding of indoor air pollution in these specific environments are important in order to improve child health. As a pollutant of both indoors and in ambient air, UFP possess the potential to harm children's health (Burtscher and Schüepp, 2012;Schüepp and Sly, 2012;Moreno et al, 2014;Reche et al, 2014;Rivas et al 2014;Viana et al, 2014), yet information concerning children's exposure to UFP is limited.…”

Due to their detrimental effects on human health, scientific interest in ultrafine particles (UFP), has been increasing but available information is far from comprehensive. Children, who represent one of the most susceptible subpopulation, spend the majority of time in schools and homes. Thus, the aim of this study is to (1) assess indoor levels of particle number concentrations (PNC) in ultrafine and fine (20-1000 nm) range at school and home environments and (2) compare indoor respective dose rates for 3-to 5-yr-old children. Indoor particle number concentrations in range of 20-1000 nm were consecutively measured dur-ing 56 d at two preschools (S1 and S2) and three homes (H1-H3) situated in Porto, Portugal. At both preschools different indoor microenvironments, such as classrooms and canteens, were evaluated. The results showed that total mean indoor PNC as determined for all indoor microenvironments were significantly higher at S1 than S2. At homes, indoor levels of PNC with means ranging between 1.09 × 10 4 and 1.24 × 10 4 particles/cm 3 were 10-70% lower than total indoor means of preschools (1.32 × 10 4 to 1.84 × 10 4 particles/cm 3 ). Nevertheless, estimated dose rates of particles were 1.3-to 2.1-fold higher at homes than preschools, mainly due to longer period of time spent at home. Daily activity patterns of 3-to 5-yr-old children significantly influenced overall dose rates of particles. Therefore, future studies focusing on health effects of airborne pollutants always need to account for children's exposures in different microenvironments such as homes, schools, and transportation modes in order to obtain an accurate representation of children overall exposure.

“…The impact of the other meteorological conditions has little been studied. A study by Reche et al (2014) has reported a little impact of solar radiation, temperature and relative humidity on the correlations of outdoor average UFP concentrations between a site outside a school and a fixed urban background station; however both sites did not record the exact same parameter, thus limiting the interpretation of the results. Meteorological conditions have lower influences on traffic counts (only to the extent of the proportion of subjects changing their mode of transportation according to the weather) and on noise levels than on UFP concentrations.…”

“…We selected NO 2 , black carbon (BC), and ultrafine particles (UFPs) given their relation to road traffic emissions in Barcelona Reche et al, 2014;Rivas et al, 2014). For UFP (in the range of 10-700 nm), we separately analyzed number concentration and lung-deposited surface area (UFP-LDSA).…”
