The detection threshold values of cis-configuration “green” odors fall in the range of 8.1 x 10⁹ to 8.1 x 10¹¹ molecules/ cm³. The detection threshold values of trans-configuration “green” odors fall in the range of 8.1 x 10⁷ to 8.1 x 10¹¹ molecules/ cm³. Statistical analysis shows that there is no significant difference between the threshold values of cis-configuration and trans-configuration “green” odors (Wilcoxon signed rank test; p> 0.01).
