Outline of Final Research Achievements

This study aimed to establish evaluation and source identification method for environmental odours using GC/MS-olfactometry considering advantages of instrumental analysis and sensory measurement. Three pretreatment operations were compared to investigate simplified, inexpensive and uncomplicated pretreatment method to concentrate environmental odours. Also sensory odour intensity scale was reconsidered and a new practical series of six dilution steps of 1-butanol with explanatory labels were established. These results can be useful for all people related to environmental odour measurement and evaluation around the world.
