| Abstract |
A total of 129 bleachery workers in two Swedish pulp mills that use ozone for bleaching were studied together with 80 non-exposed controls. The pulp mills had previously used chlorine dioxide as the bleaching agent. Participants responded to questionnaires and were subjected to spirometry and methacholine challenge testing. Area sampling showed sporadic ozone levels exceeding 0.9ppm. There was a greater prevalence of wheezing (25%) among the bleachery workers with a history of gassings than among the referents (13%). Among current smokers, the proportion with a slightly increased bronchial responsiveness to methacholine was greater among the bleachery workers. For the period from 1992 to 1996 when the mills were using ozone, there was an increased incidence rate of wheezing among the workers in the bleachery. This finding reinforces the view that repeated peak exposures to irritants must be prevented in pulp mills. |
