[Lung function and respiratory tract disease among stonewool factory workers].

Introduction: We examined the respiratory health of a Danish workforce exposed to man-made vitreous fibres (MMVF) during production.

Material And Methods: Workers with more than five years' occupational exposure to MMVF (n = 377) were compared to a group without MMVF exposure (n = 381). Respiratory health was assessed by questionnaire, dynamic spirometry, and measurement of transfer factor.
