Regulatory consensus
3 regulatory and scientific bodies have classified Vinclozolin. The classifications differ — that's the data.
| Agency | Year | Classification | Notes |
|---|---|---|---|
| EU | 2006 | Banned — endocrine disruptor (Reg 2006/1015/EC) | |
| EPA | 2010 | Registrations voluntarily cancelled | |
| TEDX | 2015 | Listed endocrine disruptor |
Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
