Published thresholds
16 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
105 ppbThe reference measurement — smelled in water. OAV is computed against this.

| 105 ppb SIDA | water | Rychlik 1998 · 2 studies | — |
In a food matrix
0.240 ppb – 1036 ppbMeasured in a real food, where the matrix shifts detection — not a clean-water value.

Measured impact first, then profile shareEvery ingredient known to contain l-limonene. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of l-limonene in it.
