PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment of the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence
The substance is readily biodegradable (72-74% within 28 d, OECD301B). Thus, the substance is considered as neither persistent (P) nor very persistent (vP).
Bioaccumulation
The BCF of test item was performed using a flow-through system with Danio rerio in accordance with 67/548/EEC method C.13 (1998). The BCF values were determined to be 244 at steady state indicating a moderate potential of the test item to boaccumualte. According to section 1 of Annex XIII of the REACH regulation (EC) No 1907/2006the test item was considered as neither bioaccumulative (B) nor very bioaccumulative (vB).
Toxicity
The lowest NOEC is 0.141 mg/L (OECD211, Daphnia magna), which is above 0.01 mg/L. Furthermore, the substance is not classified as carcinogenic, mutagenic or toxic for reproduction according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs). Therefore, the substance does not meet the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 and it is concluded that the substance is not T.
In conclusion, the substance is is not PBT / vPvB.
