PBT assessment list

ECHA’s persistence, bioaccumulation and toxicity (PBT) assessment list includes the substances undergoing a PBT/vPvB assessment that have been brought for discussion to ECHA’s PBT Expert Group.


Explanatory note

Inclusion in the list means that an informal hazard assessment for PBT/vPvB properties either is under development or has been completed since February 2013.

For each substance, the table shows the assessing or evaluating Member State (submitter), the outcome from the assessment, and the date of the latest update to the list entry.

Other process details and hazard assessment outcome documents are also available and can be accessed through the ‘Details’ icon.

One possible outcome of such an assessment is that a substance is considered not to have PBT/vPvB properties.

If the outcome is that the substance is considered to have PBT/vPvB properties, confirmation through the formal risk management and decision-making processes is needed before any regulatory action can be taken due to these properties.

The intentions of authorities to submit a dossier to the formal REACH and CLP processes are notified through the Registry of Intentions. All biocidal active substances have to undergo a formal PBT assessment. You can see the status of biocides assessments on the Biocidal Active Substances page.


The information and views set out in the PBT assessment list and in the hazard assessment outcome documents are those of the evaluating authority and do not necessarily reflect the position or opinion of the other Member States or ECHA. Neither ECHA nor the evaluating authority nor any person acting on either of their behalves may be held liable for the use, which may be made of the information contained therein. Statements made or information contained in the documents are without prejudice to any formal regulatory activities that ECHA or the Member States may initiate at a later stage. PBT assessments and their outcomes are compiled on the basis of information available by the date of the publication of the document.

Hazard assessment outcome document
Included to substances of very high concern in the Candidate List for eventual inclusion in Annex XIV on 17 January 2023 (Equivalent level of concern having probable serious effects to the environment (Article 57(f) -
environment); Equivalent level of concern having probable serious effects to human health (Article 57(f) –human health)).
The combined intrinsic properties which demonstrate scientific evidence of probable
serious effects to human health and the environment and which give rise to an equivalent
level of concern are the following: very high persistence, high mobility in water, potential
for being transported in the water phase over long distances and toxicity.
