Assessment Factors to Derive DNELs

Start date: 25 Mar. 2010

This Workshop will be held to disseminate the approaches developed by the ECETOC task force and the ERASM project. Relevant examples will be shared. Workshop participants will be asked to discuss the proposals made and to assess where the science could be further developed in support of the implementation of REACH.

The primary target audience of the Workshop are those in industry that are directly involved in the preparation of chemical safety dossiers under REACH.

Regulators and academics are invited as observers and discussion partners, and the organisers would very much welcome their input and advice.

The outcome of the workshop will be summarised as an ECETOC workshop report.

If you need any further information, please contact christa.hennes@ecetoc.org, scientific officer in charge of the event.
