Relationship between summer and winter formaldehyde levels in kindergartens and primary schools

Presents the results of formaldehyde (HCHO) concentration measurements undertaken in ten kindergartens and ten primary schools (one room each) during summer and the winter period. The buildings were of different age (1-100 years) and structure (from conventional to prefabricated type), and particle-board furniture was used in all premises. Results show that the proposed limit value of 120 mcg/m3, recommended by WHO for living accomodation, was frequlently exceeded. The seasonal differences of concentrations were statistically significant for nine kindergartens and seven schools.
