Targeted Risk Assessment (TRA)

ECETOC’s Targeted Risk Assessment (TRA) tool calculates the risk of exposure from chemicals to workers, consumers and the environment. It has been identified by the European Commission’s Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) as a preferred approach for evaluating consumer and worker health risks (ECHA, 2010 a,b).

In response to feedback received from users of the TRA, ECETOC 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 were developed in cooperation with ECHA are found in the current 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 (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 specific environmental release class (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 downloaded here together with updated user guides for these tools and ECETOC TRA Technical Reports.
