Objective: To view the indoor air quality of newly decorated apartments and its effects on inhabitant health. Methods: The authors chose randomly 82 newly decorated apartments and 16 undecorated apartments in same building as objects to be surveyed. Formaldehyde concentrations in indoor air of respective apartments were determined thrice at set time (one month, 6 months and 12 months after decoration )by colorimetry. Three hundred and thirteen residents living in decorated apartments and 20 residents living in undecorated apartments were enrolled as candidates to be questioned on health using questionnaire. Results: The formaldehyde concentration in indoor air of decorated house was significantly higher than that in air of undecorated house. Irritating symptoms and signs of eyes and respiratory tract of residents living in decorated apartment were significantly severer than that of residents living in undecorated house. Conclusion: formaldehyde poisonous to human being can be released from decorated materials and reserved in indoor air for a long time and therefore attention should be paid to reduce the formaldehyde concentration taking up residence in.
