Odour is typically the most common reason for environmental complaints received by councils and regulatory agencies.  Negative impacts from odours are generally nuisance-based and caused by a range of factors for which there is no simple assessment formula. 


Assessment of odours and investigation of odour nuisance is therefore a complex process requiring specialist skills.  Air Quality Professionals' Principal Air Quality Consultant, Tracy Freeman, has been providing clients with odour assessment and management advice for 20 years, and has been a key player in the development of odour assessment science in Australasia.
