Abstract Although peat bogs are one of Quebec's important natural resources, few scientific data exist on these workplaces which employ approximately 700 workers. These workers are exposed to high concentrations of microorganisms that could affect their respiratory health. In this study, the biological contaminants contained in the peat moss and their effects on health are identified and the air quality in processing and packaging plants equipped with dust control systems is evaluated, together with the health status of the workers. The results show that the levels of exposure to various contaminants often exceed the permissible limits. For various reasons, the control systems at source do not maintain the dust emissions at acceptable levels. The report concludes with a series of recommendations to improve the working conditions in peat bogs.
