According to the EU Regulation concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), DNELs are levels of exposure to a substance above which humans should not be exposed and have to be established by manufacturers and importers. Derived from the human health hazard assessment as part of the REACH requirements, they are exposure levels below which it is considered that adverse effects will not occur for a particular route and duration and frequency of exposure.
