Published thresholds

1 measured value 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.

Retronasal / in-mouth

6.0 ppb

Tasted rather than smelled — a different sense, not comparable.
