APPROACH TO ODOR NUISANCE

Since the promulgation of the Swiss Environmental Protection Act, the annoyance approach has been established for odor regulation. The direct scaling of the extent of annoyance in the neighborhood of odor emitting plants has led to an evaluation scheme for public odor annoyance. The problem-solving procedure starts with checking compliance with emission standards for specific substances. Olfactometry plays an important role in defining the state of the art for odor abatement systems. An evaluation scheme for odor emissions is applied. The link between emission and public annoyance gives the assessment of odor frequencies as a measure of the ambient odor burden.
