ABSTRACT

The IAQ becomes especially important to its occupants, especially for the most vulnerable risk groups, such as children and the elderly (Kukec, et al., 2013; Ferreira & Massano Cardoso, 2013). Children are part of an important risk group (Branco, et al., 2014; Viegas, et al., 2012; FuentesLeonarte, et al., 2009) when it comes to IAQ, mainly due to their body development, i.e. his respiratory system is not fully developed until the age of 6 years and breathe more proportion of air per kg (Branco, et al., 2014; Fuentes-Leonarte, et al., 2009). To make matters worse, in recent decades children spend about 1/3 of their time in the kindergarten (Ferreira & Massano Cardoso, 2013). Thus, the kindergarten acquired the status of second home for most of children, noting up an increase in the number of children attending these institutions (Saint-jean, et al., 2012). This fact is found in all industrialized countries, after the women’s entry to the labour market (Saint-jean, et al., 2012). At the same time, it is found that the frequency of diseases and the respiratory disorders increase when children start their exposure to indoor environments of kindergarten (Viegas et al., 2012).
