“…Previous studies in DCC found high concentrations of air pollutants [11,21] and a relation between some air pollutants and ventilation [24]. Nevertheless, high CO 2 concentrations may occur without higher levels of other indoor air pollutants.…”

“…Its concentration could be highly influenced by the number of occupants in the room [10], human behaviours and building characteristics [4]. A high CO 2 concentration suggests a low air supply which may elicit symptoms due to higher concentrations of air pollutants [21]. On the other hand, it can reflect an excessive number of children in the room [10], which might enhance respiratory infections.…”

“…High concentration of indoor air pollutants and carbon dioxide (CO 2 ) in DCC for children has been reported, and poor indoor air quality (IAQ) and ventilation conditions were associated with higher levels of CO 2 [21,3,15,4] and with other indoor air pollutants [24].…”

“…Proper ventilation is the most effective way to reduce indoor air pollutant concentrations [25,21]. CO 2 is considered an indirect marker of IAQ in the absence of other sources besides the anthropogenic [5].…”

CO2 concentration in day care centres is related to wheezing in attending children

Poor ventilation at day care centres (DCCs) was already reported, although its effects on attending children are not clear. This study aimed to evaluate the association between wheezing in children and indoor CO 2 (a ventilation surrogate marker) in DCC and to identify behaviours and building characteristics potentially related to CO 2 . In phase I, 45 DCCs from Lisbon and Oporto (Portugal) were selected through a proportional stratified random sampling. In phase II, 3 months later, 19 DCCs were further reassessed after cluster analysis for the greatest difference comparison. In both phases, children's respiratory health was assessed by ISAAC-derived questionnaires. Indoor CO 2 concentrations and building Communicated by David NadalWhat is known-what is new: Poor ventilation at day care centres (DCC) was already reported. The results of the present study suggest that poor ventilation in DCC could be related to wheezing in children. Even though natural actions could not be sufficient to provide ventilation and reduce CO 2 to acceptable levels, the increment of natural ventilation through effective open window practices and adjusting the number of children in each classroom may be considered.P.

Abstract. Children in kindergartens spend between five and ten hours a day, the quality of air inside is very important. Kindergartens are public buildings. Kindergartens in Poland do not have mechanical ventilation, most often use stack ventilation, which is frequently aided by airing. The three considered buildings were located in eastern Europe. The main objective of the research was to evaluate the interior conditions, especially with regard to carbon dioxide concentration. In the afternoon, the permissible level of carbon dioxide concentration was substantially exceeded (by 190% at the most in first series of measurement). The present research has resulted in considerable improvement of indoor conditions in the analyzed kindergartens (less than 140% in third series of measurement). The presence of children and ventilation habits seemed to be the main determinants of IAQ and carbon dioxide.
