PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance is not readily biodegradable and it is not hydrolysable. Since the half-life in freshwater is more than 40 days it should be considered to be persistent.
The substance does not bioaccumulate. It has a very low log Pow of -3.10 at 20° C.
The substance is not classified as carcinogenic (Cat 1 or 2) or mutagenic (Cat 1 or 2), toxic for reproduction (Cat 1, 2 or 3) nor is there other evidence of chronic toxicity relevant for classification as Xn; R48 or T; R48. The predicted No Observed Effect Concentration for freshwater organisms is based on acute algal toxicity (EC50) of > 100 mg/l (growth rate). This results in a PNEC calculated above 0.01 mg/l using an assessment factor of 1,000, which can be considered as a long-term No Observed Effect Concentration. Therefore, the substance is not toxic according to the criteria included in Annex XIII, paragraph 1.3.
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.
