| dc.description.abstract | Odour emissions can cause serious annoyance in the neigbourhood of the emission source. In Malaysia, the Olfactometer is used to measure the odour emission which reports odour concentration value. The Olfactometer is very expensive and requires professional odour operator to conduct the equipment. Therefore, this research was conducted to develop on alternative odour measurement method using the Triangular Odour Bag concept. The uniqueness of this study was the design of an illustrated odour wheel and the pleasantness scales as additional odour assessment parameter. During odour sampling and measurement, several variables that might give changes to odour concentration value have been detected. The variables (size of panels, number of reused odour bag and storage time of the sampling bag) were screened in order to check their significance by conducting experiments using factorial design. The results show that out of the three variables, only the number of reused odour bag and storage time of the sampling bag significantly influence odour concentration. At the end of the study, a decision tree for sampling and odour measurement was suggested for laboratory odour measurement analysis. The decision tree developed from this study enables the identification of the suitable odour assessment procedure and equipments to a site’s condition. | en_US |
