• A survey investigating the relationship between odour impact, wellbeing, odour observation, and perception, is implemented.
  • It was found that odour impact was determined by a small number of factors including distance, odour legislation, and odour annoyance.
  • Factors such as odour frequency also play a role in determining odour impact.
  • The implications of this research and the techniques used are discussed.


In the context of environmental malodour, surveys are valuable as they allow for the relatively detailed analysis of multiple factors pertaining to odour perception and subsequent reaction. However, the causes for an individual to experience odour impact while a neighbour will not are still not understood. The goal of this current survey design was to consolidate varying research paths for surveys within the environmental odour research space. This survey investigated the area of effect for wastewater treatment plants by using stratified random sampling techniques that radiated from the industrial areas. Additionally, this survey provided a “non-alerted” response to environmental malodour that represents a step forward for ecological validity. The authors found a small number of items relating to odour annoyance and home ownership that can be used in order to predict odour impact for individual community members. However, the authors also did not find any relationship with odour impact and perceived control. This survey design and analysis reconciles the varied approaches towards community surveys administered in prior literature, as well as providing information to improve future community engagement policies.
