PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The registered substance is not considered readily biodegradable because the 10-day window is not fulfilled. However, as 77% biodegradation was observed after 48 days of exposure in the biodegradation study, the registered substance is not considered persistent (P). In addition, with a log Kow lower than 4.5 and an experimental BCF value well lower than 2000 L/kg, the registered substance does not meet the criterion for bioaccumulation (B). For the T criterion, no chronic NOEC/EC10 are available. However, the most sensitive species in acute conditions is fish with a 96h-LC50 value greater than 0.1 mg/L (at 1.09 mg/L), therefore the registered substance is presumably not toxic (T).
In conclusion, the registered substance could not be considered as a PBT or vPvB substance.
- Likely routes of exposure:
None
