Persistence
Criteria in the REACH Legislation: Critical Evaluation and
Recommendations

Substances that are persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumulative (vPvB) pose a particular risk to the environment. They are identified as substances of very high concern under the new European Regulation No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). Substantial obligations are imposed on the application of these substances. In Annex XIII of the REACH regulation, criteria for the identification of PBT and vPvB substances are described. As the identification of a substance according to these criteria requires costly, time-consuming experiments and involves animal testing, the PBT/vPvB assessment starts with the evaluation of screening criteria. Those substances that are suspected to be PBT/vPvB are subject to further testing. In contrast to bioaccumulation and toxicity, testing persistency according to the Annex XIII criteria does not require animal tests. Therefore, the definitive assessment of possible PBT/vPvB substances usually starts with the experimental determination whether the substance is persistent or not. If the substance is not persistent, further testing can be avoided. The following report about “Persistence Criteria in the REACH Legislation” was prepared by order of the UBA. The authors examine the reliability of the screening criteria and evaluate the suitability of the current Annex XIII persistency criteria. Based on these findings, they propose a testing strategy for the identification of persistent chemicals and recommend a modification of the Annex XIII persistency criteria. |
