A Comparative Study of Japanese and European Olfactometry Standards

This report provides a comparative study between the odor measurement method by olfaction, which has been adopted as the Offensive Odor Control Law in Japan and the dynamic olfactometry, which has been standardized in Europe. Dilution accuracy, panel selection and odor measurements have been compared in this study. As a result of the dilution test with three standard odorants, a 46% decrease in the concentration of hydrogen sulfide at a high dilution ratio has been observed using the olfactometer, while the Japanese method has shown good performance. Twenty people have been given both screening tests. Eighteen people have passed the Japanese test, while only seven people have passed the European test. In the odor measurement of three standard odors and six actual source samples, if the panel is the same, the results of both methods have corresponded well… Get the article to read more.
