Subjective indoor air quality in schools in relation to exposure.

Relates exposure measurements for indoor air quality in schools to perception of IAQ by employees. A questionnaire was used to gather information on subjective air quality, domestic exposures and health aspects. 38 schools were covered in the study. A 53% section of personnel reported bad or very bad indoor air quality. Worst reports came from the younger personnel, those dissatisfied with their psychosocial work climate and those not exposed to domestic tobacco smoke. Less IAQ dissatisfaction was reported for older schools and those with displacement ventilation. No link was found between complaints and air change rate or CO2 concentration.
