PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance is not PBT or vPvB as it is not expected to bioaccumulate in organisms based on its low Pow of <0 at 20°C and a measured BCF in carp of < 1.3. A weight of evidence assessment for persistence is appended to Section 13 of the CSR. This concludes that under aerobic conditions sulfolane can degrade completely to carbon dioxide, water, biomass and sulphate within the REACH persistence criteria for surface water or soil compartments. Under certain low nutrient or anaerobic conditions sulfolane may however persist in the environment. Sulfolane would meet the criteria for toxicity based on its classification as a Category 1 reprotoxicant.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
