ECETOC Targeted Risk Assessment Tool Update to TRAv3.1

ECETOC Targeted Risk Assessment Tool Update to TRAv3.1
and Publication of related Addendum to Technical Report No. 114
on the Technical Basis for version 3 of the TRA

Brussels, June 2014

In response to feedback received from users of the TRA, ECETOC has further improved the consumer portion of the model by the inclusion of the ability to account for infrequent uses of consumer products. The changes which have been developed in cooperation with ECHA are now found as version 3.1 of the TRA and are also to be found within version 2.3 of Chesar (https://chesar.echa.europa.eu/).

A detailed explanation of the rationale for the changes is contained in an Addendum to ECETOC Technical Report 114 (just published as ECETOC Technical Report No. 124) which provides further clarification of how ECETOC has applied ‘transfer factors’ in the TRA’s prediction of oral, dermal and inhalation exposures. These improvements now enable the information contained within developments such as the DUCC Specific Consumer Exposure Determinants (http://www.ducc.eu/Activities.aspx) to be suitably processed.

The update to version 3.1 was used as an occasion to include an updated SpERC list and improvements of the functionalities by offering the export and import of single substance datasets. Version 3.1 is available both as an integrated model and a standalone version for the consumer part, and can be found at the ECETOC TRA website https://www.ecetoc.org/tools/targeted-risk-assessment-tra/ together with updated user guides for these tools and ECETOC TRA Technical Reports.

The Addendum to ECETOC Technical Report 114 has been published as ECETOC Technical Report 124: Addendum to TR114: Technical Basis for the TRA v3.1. The Summary and free PDF of the report are available at http://bit.ly/ecetoc-tr124
