title: [Measurement and evaluation of environmental odors].
abstract: The odor problem in the vicinity of a sludge drying plant was solved by installation of a biofilter. The success of this measure was examined by olfactometric measurements such as dilution to threshold determination and scaling of hedonic tone. The odor emissions were evaluated by questioning of the population in the neighbourhood of the plant. The question of acceptability was answered by a simple empiric model based on the percentage of highly annoyed people in the afflicted areas.
