2013 CASANZ Conference. Odour Special Interest Group Workshop


The coming 21st International Clean Air and Environment Conference (7th to 11th September, 2013) in Sydney will have a special place for an Odour Special Interest Group Workshop. This workshop will take place on Sunday, the 8th of September, 2013. Odour is probably the most widespread and complex local air pollution problem in Australia and New Zealand. It accounts for the majority of complaints received by environmental authorities and can be a major source of annoyance and stress in affected communities.

Odour problems involve a complex set of scientific, analytical, technological, physiological and psychological factors. Effective long-term solutions to odour problems or effective planning to avoid such problems require an understanding of many of these factors. However, while the science surrounding odour is rapidly developing, there still remain major gaps in our knowledge of some of the key issues that are important to odour-related annoyance.

There are important challenges to the air quality community involved in odour to advance the technical, planning and regulatory aspects of odour assessment and management. OSIG is an important forum for the exchange of information, and in encouraging improved practices in odour measurement, modelling, assessment, control, management and monitoring.
