ABSTRACT
Due to the developing physiological and immunological systems and greater inhaled breath per unit mass, children represent one of the most vulnerable groups of a society with regard to potentially harmful effects induced by air pollution (Burtscher & Schüepp 2012, Fonseca et al. 2014, Foos et al. 2008). In their earliest years, children stay mostly indoors where they are exposed to a complex mixture of air pollutants including particulate matter, various gaseous compounds, and microorganisms generated in different microenvironments. During a regular day, children may spend at schools up to 10 h per day. Therefore, indoor air quality found in these environments may significantly impact on the respective health outcomes of this susceptible group and requires particular attention (Oliveira et al. 2013).
