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 air
87.0 ppbAirborne detection — not comparable to a water threshold.
| Threshold | Matrix | Source | Paper |

| 87.0 ppb | air | Nagata 2003 | — |
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.
Thresholds in published tables
Numbers printed in open-access papers, grouped by the medium the table states. Median and full range of the values; “agree” means two or more papers whose middle 80% of values sit within 100×. Not reviewed.
| Medium | Median | Range | Values | Papers | Papers agree? |
|---|---|---|---|---|---|
| air | 2190 µg/L air | 0.37–6e+03 | 3 | 2 | no (4.2 decades) |
| food matrix | 4e+04 ppb | 4e+04–4e+04 | 1 | 1 | one paper |
| unstated | 370 ppb | 370–800 | 3 | 2 | yes |

Measured impact first, then profile shareEvery ingredient known to contain butyl formate. 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 butyl formate in it.
