PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The persistency assessment is based on the screening criteria in Annex XIII of the REACH Regulation. In a guideline study on readily biodegradability following the OECD 301B (Desmares-Koopmans, 2016), no significant biodegradation was observed for the substance. As the substance is concluded not to be readily biodegradable and appears to be hydrolytically stable, it should be considered potentially P and vP.
The bioaccumulation assessment is based on the screening criteria in Annex XIII of the REACH Regulation. The available evidence on the bioaccumulation potential for the substance indicates that the screening criteria for bioaccumulation potential (B and vB) are not met. Based on a log Pow of 2.2, a low BCF can be estimated. Since the log Pow of the substance is < 4.5, the screening criteria for bioaccumulation are not fulfilled and the substance is concluded not to have a bioaccumulative potential (not B / not vB).
The toxicity assessment is based on the screening criteria in Annex XIII of the REACH Regulation. The test substance is classified as Mutagenic category 2 and STOT RE 2 according to the Regulation EC N° 1272/2008, hence fulfilling the criteria to be considered as T.
As a conclusion, taking into account the conclusions the substance is P and vP and T but not B/vB. Hence, the substance should not be considered as a PBT/vPvB substance.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
