An effective odour regulatory strategy meets other requirements then the current nuisance laws based on complaint or definition of public nuisance and other regulation based on threshold measurements present. Odour Impact Model (OIM) is of interest because many parameters are considered including the impact of odours on the community. The impact of odours is judged on an emission base quantitatively (quantity and area affected using a mathematical model) and also qualitatively (degree of annoyance).

Very interesting in the review of current laws and regulations and their limits are presented. Shows the need for the development of regulations that gives a clear definition of the problem, gives and defines ways of measuring and addressing the odour problem (that are reproducible, low cost and effective) and consider the capacity (economical and technical) of the industry to control their emissions.
