Substance authorisations

Substance authorisations specify which food/substance combinations are authorised for (agricultural) use. If substance authorisations are used, then only the food/substance combinations that are specified in the data are assumed to be authorised and all other combinations are assumed to be not authorised. This information may, for instance, be used to determine whether concentration measurements below the LOQ or LOD could be assumed true zeros. I.e., if a food/substance combinations is assumed to be unauthorised, then the LOQ, LOD may be assumed to be a zero.
