“…In addition, we manually searched selected publications for relevant articles: the journal Indoor Air (previous 10 years); proceedings of the triennial International Conference on Indoor Air Quality and Climate (‘‘Indoor Air ’90“ through ‘‘Indoor Air ’02”); and the Healthy Buildings 1997 and 2000 conferences. We also used several unpublished reports or bibliographies (Bayer et al., 2000; Daisey and Angell, 1998). Finally, we reviewed other articles as appropriate to provide background information on current conditions in schools.…”

Do indoor pollutants and thermal conditions in schools influence student performance? A critical review of the literature

There is more justification now for improving IEQ in schools to reduce health risks to students than to reduce performance or attendance risks. However, as IEQ-performance links are likely to operate largely through effects of IEQ on health, IEQ improvements that benefit the health of students are likely to have performance and attendance benefits as well. Immediate actions are warranted in schools to prevent dampness problems, inadequate ventilation, and excess indoor exposures to substances such as NO(2) and formaldehyde. Also, siting of new schools in areas with lower outdoor pollutant levels is preferable.

“…Branis et al (2005) studied correlation coefficient between PM 10 , PM 2.5 , and PM 1 concentrations in three different points in a classroom for 12 hours [7]. Bayer et al (1999) searched the factors having negative impacts on indoor air quality in schools [8]. Mcleod (2008) statistically evaluated the values of CO 2 , temperature, relative humidity, and total concentration of fungal spore in a school [9].…”

This study was carried out in order to determine the indoor air quality of the classrooms existing in university (Turkey). Relative humidity, temperature, carbon dioxide, radon, and particulate matters (PM 0.5 , PM 1.0 , PM 2.5 , PM 5.0 , and PM 10 ) were taken into account as the parameters of indoor air quality measurements. The results obtained from the present work were interpreted by comparing them with the standards of different countries. The relations between all parameters were statistically examined by means of correlation and regression analysis in SPSS 17 statistical program. As a result, it was observed that indoor temperature was lower than the standards, yet carbon dioxide and PM values were higher than the upper limit, but relative humidity level was within comfort conditions. The average indoor radon concentrations were found to be below the recommended reference levels for International Commission on Radiological Protection (ICRP), yet it was seen that the results were relatively higher in comparison with the worldwide values. In addition, it was determined that there was a meaningful relation between outdoor relative humidity, indoor relative humidity, and particulate matters in different diameters. Some solutions were suggested for the treatment of the indoor air quality for each parameter.

“…It has been estimated that there were 6.8 million children with asthma (ALA, 2007) in the US, which was the principal cause of school absenteeism accounting for 20% of lost school days in elementary and high schools (Bayer et al, 2000). Demir et al (2004) reported the prevalence of asthma in 1992,1997, and 2002 at a primary school in Ankara, Turkey, as 8.3%, 9.8%, and 6.4%, respectively.…”

a b s t r a c tConcentrations of volatile organic compounds (VOCs), including formaldehyde, in classrooms, kindergartens, and outdoor playgrounds of three primary schools were measured in spring, winter, and fall terms inİzmir, Turkey. A health-risk assessment was conducted for odor detection, sensory irritation, chronic toxic effects, and cancer. Active sampling was applied for VOCs and formaldehyde on Tenax TA and DNPH tubes, respectively. VOCs were analyzed in a thermal desorption-GC-MS system. Formaldehyde analysis was performed using an HPLC instrument. Benzene, toluene, and formaldehyde were the most abundant compounds with 95th percentile indoor air concentrations of 29, 87, and 106 g/m 3 , respectively. Naphthalene and xylenes followed them with an order of magnitude lower concentrations. Two isomers of dichlorobenzene (1,3 and 1,4) were the other notable compounds. The concentrations were utilized to classify the indoor air pollutants with respect to potential health effects. In addition, carcinogenic and chronic toxic risks were estimated using Monte-Carlo simulation. Formaldehyde appears to be the most concerning pollutant with high chronic toxic and carcinogenic risk levels according to the health assessment followed by naphthalene, benzene, and toluene due to their chronic effects.
