Mould & Other Bioaerosols

Biological contaminants that may affect the health of building occupants are not limited to fungi (mould), but may also include bacteria as well as allergens produced by pets, dust mites, cockroaches and rodents. Many bioaerosols are common to both indoor and outdoor enviroments. However, the comfort and health of building occupants can be affected where there is an indoor accumulation, such as may result from a catastrophic event (e.g., flooding or sewage back-up / spill), or poor building maintenance, design or operation (e.g. chronic water intrusion or condensation).
