Published thresholds

3 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

2.3 ppb – 1245 ppb

Measured in a real food, where the matrix shifts detection — not a clean-water value.

Threshold	Matrix	Source	Paper
2.3 ppb	water (food: rum)	Literature corpus	37284321
107 ppb	water (food: honey)	Literature corpus	36819689, 37284321
1245 ppb	water (food: unknown)	Literature corpus	36819689

Only values we can attribute are listed. Where a compendium's licence does not permit public attribution its figures are omitted here, so every number on this page traces to a citable source.
