Table 4–3. Summary of cross-sectional studies that used questionnaires to assess the health effects of indoor air contaminants in general or CCP specifically

Studies of indoor air contaminants:
	Skov et al. 1987, 1989	Denmark	Questionnaires were sent to 4,369 municipal workers in different buildings. Ambient measurements were taken for a large number of factors.	424 men	110	26	Clerks had the highest frequency of mucosal irritation; social workers had the highest frequency of general symptoms. Other significant correlations with mucosal irritation and general symptoms included sex, job category, photoprinting, and VDTs. Older buildings had lower incidences, but no relationship was found between naturally and mechanically ventilated buildings. Handling CCP was related to mucous membrane symptoms (OR=1.3; P<0.0001) and general symptoms (OR=1.6; P<0.0001).
				1,102 women	397	36

1. The number of CCP-exposed workers surveyed was not generally known except for those responding to the surveys; therefore, response rates were unknown.
