Relationship between summer and winter formaldehyde levels in kindergartens and primary schools Available to Purchase

Presents the results of formaldehyde (HCHO) concentration measurements undertaken in ten kindergartens and ten primary schools (one room in each) during the summer and the winter periods. The buildings were of differing 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 μg/m³, recommended by WHO for living accommodation, was frequently exceeded. The seasonal differences of concentrations were statistically significant for nine kindergartens and seven schools.
