Determining DNELs

Producers and importers of a chemical substance must define DNELs in the REACh dossier, in order to protect workers, consumers and the general population potentially exposed to the chemical substance.

DNELs must be defined for several types of population: workers, consumers and humans via the environment.

This fact sheet will help you understand how DNELs are calculated and defined, and their impact on the substance to which they apply.
