Published thresholds
25 measured values from the literature. Grouped by what was actually measured — a threshold smelled in clean water, tasted in the mouth, or measured in a real food are three different quantities and are not pooled.
Orthonasal, in clean water
2502 ppb – 6350 ppbThe reference measurement — smelled in water. OAV is computed against this.

In a food matrix
0.100 ppb – 141 ppbMeasured in a real food, where the matrix shifts detection — not a clean-water value.
