“…Of the 38 studies reviewed, only three studies [31,42,47] compared IAQ between urban schools and rural schools. A 2010 study that compared IAQ in 17 urban and rural preschools in Korea [42] showed that indoor and urban concentrations of common pollutants were higher than those in outdoor and rural areas.…”

School buildings are one of the most commonly occupied building types for children, second only to their homes. Indoor environmental quality (IEQ) is an ongoing issue in schools, especially in urban environments where students are exposed to higher levels of outdoor pollutants. To examine this issue, five elementary school buildings located in a major city on the East Coast of the United States were selected for one-week of quantitative IEQ measurements, with a satisfaction survey collected from teachers at the selected schools. The schools included three high-performance schools, one recently renovated school, and one conventional school. Despite building designers and operators following the recommendations of current high-performance design standards, the three high-performance school buildings did not have measurably better IEQ than the renovated and conventional school buildings, nor were they perceived as better based on the satisfaction survey. This indicates that current high-performance design standards may not place enough emphasis on reducing health-related pollutants in urban schools.

“…However, there is very little information about the effectiveness of these practices. Previous indoor air quality studies in Kuwait have investigated school classrooms and homes [20][21][22][23][24]. Other studies in the region examined indoor and outdoor PM concentrations during dust storm events [25,26].…”

Kuwait is a developed Middle Eastern country that is impacted by frequent dust storms from regional and/or remote deserts. The effectiveness of keeping homes tightly closed during these events to reduce dust exposures was assessed using indoor and outdoor particle samples at 10 residences within the metropolitan Kuwait City area. Specifically, this study compared indoor and outdoor levels of black carbon and 19 trace elements (Na, Mg, Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Sr, and Zr) during dust and non-dust events and found that particle penetration efficiencies were lower during dust storm events (less than 20–30%) than during non-dust storm events (40–60%). Coarse particles had lower penetration efficiency compared to fine particles, which is due to differences in infiltration rates and settling velocities between these two size fractions. Our findings suggest that increasing home insulation could be an effective strategy to reduce indoor exposure to crustal particles from dust storm events in residential houses of Kuwait City.

“…The Fluke 975 AirMeter automatically compensates for barometric pressure changes and has an extensive discrete or continuous data logging capacity. In this present study, the measuring instruments were located approximately 1 m away from walls and mounted on a flat surface with a height of 1.5 m in order to simulate school children breathing zone [48,49,50].…”

This study was carried out to assess indoor air quality (IAQ) in schools in Akwa Ibom State of Nigeria during the rainy (June-July) and dry (November-December) seasons of 2018. IAQ parameters were examined to assess pollutant levels in schools within Akwa Ibom State in single setting only (naturally ventilated classrooms). Schools were randomly selected from two zones: zone 1 which is located within the Capital City (Uyo metropolis) and represents the 'urban sector', and zone 2 which is located within the southern part of the state in close proximity to the oil and gas industrial region and represents the 'industrial sector'. Indoor air investigation included the following parameters: particulate matter (PM 1 , PM 2 , PM 5 , and PM 10), carbon monoxide (CO), carbon dioxide (CO 2) levels, temperature and relative humidity, which were simultaneously measured in fourteen (14) sampling days using Fluke 985 Particle Counter and Fluke 975 AirMeter. Multiple statistically analysis techniques were used to compare IAQ parameters and test for significant differences between the zones (urban vs. industrial) and annual seasonal variations. The concentrations of particulate matter (PM) in the naturally ventilated classroom in industrial zone during the rainy season ranged from 5152-5984 μg/m 3 for PM 1 ; 2744-3207 μg/m 3 for PM 2 ; 137-149 μg/m 3 for PM 5 ; 38-46 μg/m 3 for PM 10 and in urban zone, the concentrations of PM ranged from 1978-2491 μg/m 3 for PM 1 ; 1010-1311 μg/m 3 for PM 2 ; 38-56 μg/m 3 for PM 5 ; 15-24 μg/m 3 for PM 10. During the dry season, the concentrations of PM in the naturally ventilated classroom in industrial zone ranged from 6138-6999 μg/m 3 for PM 1 ; 2984-3980 μg/m 3 for PM 2 ; 146-159 μg/m 3 for PM 5 ; 47-59 μg/m 3 for PM 10 and in urban zone, the concentrations of PM ranged from 2556-3972 μg/m 3 for PM 1 ; 1911-2311 μg/m 3 for PM 2 ; 51-66 μg/m 3 for PM 5 ; 18-34 μg/m 3 for PM 10. Results of this study has revealed that the concentrations of PM 1 , PM 2 , PM 5 , and PM 10 measured in the naturally ventilated classroom in industrial zone were significantly (p < 0.001) higher than those measured in the urban zone during both rainy and dry seasons. In this present study, the concentrations of PM 10 measured were found to be much lower than the ambient maximum contaminant level for airborne PM 10 standard promulgated by the United States Environmental Protection Agency (US-EPA) (150 μg/m 3 daily average and 50 μg/m 3 annual average) and World Health Organization (WHO) PM 10 guidelines values (50 μg/m 3 daily average and 20 μg/m 3 annual average). Apart from re-suspension of atmospheric particles, anthropogenic activities in industrial zone significantly influenced the measured concentrations of PM compared to those measured in urban zone. In addition, the lower concentration of CO and CO 2 measured indicated adequate air exchange at the time of the assessment in the naturally ventilated classrooms during the sampling period. The results obtained reveal important contributions towards understanding o...
