Threshold Odors of Organic Chemicals

ture to discover gaps in the technology.2 Subsequently, recommendations were made for experimental research to fill these gaps. Phase two, a laboratory study, was devoted to an evaluation of the various methods of testing for odor in water and the factors affecting results. The effects on the results reported by a given odor panel member of other persons present and of the chemicals used, of temperature, and background odor have been reported.3 The application of the reported results to laboratory practice in order to determine the threshold
