Abstract
The purpose of this study was to determine the actual state of the indoor air quality in newly built or remodeled kindergartens by TVOC and HCHO concentration and teachers' responses. The field measurements on the levels of TVOC and HCHO were carried out in six classrooms of newly built or remodeled kindergartens before their opening. The interviews with teachers of subject kindergartens were carried out at the end of the first semester. The contents of the interviews were teachers' subjective responses and symptoms of the kindergarten pupils on the Sick New-School Syndrome. The results are as follows; the mean value of TVOC concentration in the classrooms of kindergartens ranged from 0.10ppm to 0.42ppm, which can theoretically exert a harmful influence on residents. The mean value of HCHO concentration ranged from 0.00ppm to 0.03ppm, which does not exceed the standard. The TVOC concentrations of the more ventilated kindergartens were lower than the others. Also, the classrooms with high concentrations of TVOC showed negative responses or symptoms in teachers and kindergarten pupils.
