Health Effects from Mould Exposure in Indoor Environments - revised

Topics: Contaminants and Hazards, Biological Agents, Indoor Air Location: General, Canada

Moulds are naturally occurring and widespread in the environment; therefore, it is not possible to eliminate exposure. Sufficient evidence exists to conclude that exposure to mould in indoor environments is associated with asthma and asthma-like symptoms (in asthmatic people), upper respiratory tract symptoms, cough and wheeze, and hypersensitivity pneumonitis in susceptible people. There is insufficient evidence to conclude that a causal relationship exists between mould exposure in indoor environments and human health effects (although associational relationships exist for some health effects as indicated above). It is not possible to set guidelines based on levels of exposure at which effects will or will not occur, as a reliable quantitative relationship between mould exposure and health has not been established.
