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 (Link to Chesar website).
Version 3.1 is available both as an integrated model and a standalone version for the consumer part, and together with updated user guides can now be downloaded from this webpage. 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 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.
The ECETOC Targeted Risk Assessment (TRA) tool was launched in 2004. The TRA consists of 3 separate models for estimating exposures to workers, consumers and the environment that arise during a series of events (‘exposure scenarios‘). In order to ensure that the TRA fully aligned with the expectations contained in Chapters R12-R16 of the Technical Guidance on Information Requirements and Chemicals Safety Assessment (IR&CSA), ECETOC released version 2 of the TRA in 2009. The general success of the TRA concept is witnessed by the fact that, by the beginning of 2012, there were over 11,000 downloads of the TRA Tool.
Following the completion of Phase 1 of REACH in December 2010, ECETOC approached users of the TRA to seek their ideas for how the TRA might be further improved. The aim of this exercise was to ensure that key learnings arising from the use of the TRA in 2009/10 could be captured into an updated version that would be available for use in Phase 2 of REACH. The intention was not to radically overhaul the TRA, rather to further improve its accuracy and flexibility, within its existing framework.
Version 3 of the Targeted Risk Assessment (TRA) Tool
In April 2012, ECETOC launched version 3 of the Targeted Risk Assessment (TRA) Tool together with updated user guides. The TRA Tool is available in two forms: as an integrated exposure/risk assessment tool covering worker, consumer and environmental exposures; and as a standalone consumer exposure estimation tool. Both forms of the TRA are downloadable from the TRA website without charge, together with their supporting user guides. It is not ECETOC‘s intention to support a standalone worker version 3 of the tool. Technical Report No. 114 details the full technical basis for version 3. The technical basis for TRA v1 and TRA v2 remains accessible via the Technical Reports 93 and 107.
ECETOC has been working with the European Chemicals Agency (ECHA) as part of its work activities associated with the delivery of a revised version of the Chesar Chemical Safety Assessment tool (http://chesar.echa.europa.eu/). The new version of Chesar was released in June 2012 and is intended to directly reflect version 3 of the TRA for both worker and consumer exposures. Furthermore, Chesar v2 allows the incorporation of the Specific Environmental Release Categories (SpERCs) that are included as a key element of the environmental component of the TRA v3.
