An OEL is set for ethylenediamine, for which the scientific base is the same set of toxicological data as available in this dossier (ACGIH 2001). This is a common national OEL value within the EU. Therefore the OEL value has been used as a DNEL. No quantitative data on local long-term effects on skin or respiratory tract can be derived. Ethylenediamine is also classified as a skin sensitiser and a respiratory sensitiser. No quantitative data is available for these effects.

Additional information - General Population
Ethylenediamine is not used in applications for the general public in the EU. In its use as intermediate, ethylenediamine is consumed on reaction. Therefore no DNEL´s are derived for the general public, expect the oral long-term DNEL, to be used in assessment for man exposed via environment.
