Abstract

This study was followed up asthma incidence rate in primary schools indoor air quality. To investigate the history and prevalence rate of allergic diseases(asthma, atopy dermatitis, allergic rhinitis and conjunctivitis), the standardized and generally used International Study of Asthma and Allergies in Childhood(ISAAC) questionnaire was used to conduct the symptom survey for all participating subjects. The concentrations of major indoor air pollutants(dust mite allergen, aldehydes , VOCs, TBC, phthalate) were observed from April to May 2007. Sampling was undertaken at 19 primary schools. The sampling sites of air pollutants are classroom’s indoor and hallway. Dust mite allergen part it was detected from the case classroom and infirmary. The exposure quality of aldehyde and the place pollution level was indoor＞outdoor＞hallway, which whole is disease incidence rate high group appears more highly the low group than. The partially result of formaldehy and VOCs, the concentration of high environmental disease incidence rate showed also high. However, house dust allergen, TBC and phthalate measurement school was not the effect where the comparison of difference.
