Recently, the sickness symptom related to school environment or so-called "sick school syndrome" is a social problem. Sick school syndrome is caused by chemical substances emitted from building materials and educational products.Some of the studies on sick school syndrome from a point of indoor air environment have been reported, however, we can't find the useful information on the emission of chemical substances from educational products. In addition, its size and form are various and different, and the standardized testing method has not been established.In this study, we determined the emission rates of chemical substances from some educational products and predicted pollutant concentrations in a classroom where the educational materials were placed. It turned out that the predicted value was not so serious to threaten health in an assumption of the steady-state under complete mixing, however, in an actual classroom where distribution of concentration consequently appears, concentration at the place near the emission source might be expected to be more higher values than our predicted ones.
