Published thresholds
2 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.
In a food matrix
0.430 ppbMeasured in a real food, where the matrix shifts detection — not a clean-water value.
| Threshold | Matrix | Source | Paper |
|---|---|---|---|
| 0.430 ppb | water (food: unknown) | Literature corpus | 35999251 |
In air
0.030 ppbAirborne detection — not comparable to a water threshold.
| Threshold | Matrix | Source | Paper |
