Media enquiries: ECHA Press
The European Chemicals Agency (ECHA) has published a new chapter in the Guidance on information requirements and chemical safety assessment: Chapter B8 - Scope of Exposure Assessment.
Helsinki, 31 August 2011 - This new chapter aims to help registrants to determine the scope of the exposure assessment and when it is necessary to conduct it, based on the outcome of the hazard assessment for their substance. Guidance on how to assess the exposure and on the subsequent risk characterisation are already contained in other chapters of the Guidance on Information Requirements and Chemicals Safety Assessment (IR/CSA Guidance).
Exposure assessment for subsequent risk characterisation is required for substances registered above ten tonnes if the substance is classified as dangerous and/or has PBT/vPvB properties. This new guidance on the scope of exposure assessment clarifies that:
- the scope of the exposure assessment should address the toxicological effects, routes of exposure and environmental protection targets identified from the outcome of the hazard assessment;
- the exposure assessment should cover all hazards identified and is not only limited to classified hazards or adverse effects observed at doses/concentrations where classification is triggered.
