Endotoxins isolated from the air of a Danish paper mill and the relation to change in lung function: an 11-year follow-up.

Background: A decline in lung function has been associated with farming, cotton spinning, and work in the animal feed industry. The aim of the study was to reveal if loss of lung function was associated to work at a paper mill.

Methods: Ninety-seven male paper workers (PW), and 55 control workers were examined.
