Abstract:		"Odor pollution has become a serious environmental problem arising from volatile organic compounds (VOCs) and other pollutants. But the studies on odor intensity and other olfactory evaluations are seriously influenced by the diversity, distinct concentration fluctuation and complex interaction of pollutants. In order to explore the relationship between odor intensity and components concentrations of odor mixture, several typical VOCs in indoor environment were used to simulate odor mixtures. A panel of six sensory assessors was employed to rate the odor intensities of the mixture and its unmixed components. The outcome showed that the presence of an odorant barely influenced the odor intensity of the mixture when its nature logarithm of odor activity value (OAV) was lower than 20% of the mixture's total amount. The application of this method as a pretreatment method for the odor mixture could apparently simplify the studies on odor interaction and olfactory evaluation"
