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

	Study	Country	Methods	CCP-exposed workers			Results
				Number responding to survey[1]	Workers with complaints
					Number	%
	Öberg 1980 (cited in Murray 1991[2])	Sweden	Authors surveyed 205 workers; 74% handled more than 10 CCP forms daily.	205	82	40	Respondents complained of itching and dryness of the hands, eyes, and mouth; 4 reported eczema.
	Sondergard 1981 (cited by Murray 1991 and Olsen and Mørck 1985[2])	Sweden	Surveyed offices of an airline.	93	68	73	Symptoms not described; dose-response connection was not statistically significant because of small numbers of workers in two groups.
	Menné et al. 1981	Denmark	Authors surveyed those with CCP exposure at telephone company by asking about symptoms caused by CCP.	1,855	208	11	5.1 % of men (32 of 624) and 14.3% of women (176 of 1,231) reported skin symptoms or mucous membrane irritation.

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