Formaldehyde vapor in mobile homes: a cross sectional survey of concentrations and irritant effects.

Abstract
Sixty-five Wisconsin mobile home households volunteered for an assessment of indoor formaldehyde gas. Sixty-one teenage and adult occupants completed health questionnaires. Formaldehyde concentrations ranged from less than 0.10 to 0.80 ppm, with the risk of ocular discomfort showing a positive dose-response relationship.
