[Moulds--occupational and environmental hazards].

This paper reviews the most common health effects of exposure to moulds. Allergens of mould may induce rhinitis or bronchial asthma, whereas occupational exposure frequently leads to hypersensitivity pneumonitis. Moulds also reveal cancerogenic and neurotoxic properties. They may cause serious infections, organic dust toxic syndrome and sick building syndrome. Methods used to evaluate exposures and decrease concentrations of spores in the house environment are also presented.
