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