PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
While the substance itself does not meet P criteria as demonstrated in a recent enhanced ready biodegradation study, it did not reach 50% biodegradation within 60 days due to a prolonged lag time. Nevertheless, the substance was significantly degraded (32%) within 60 days demonstrating that the parent had primarily degraded within the period of the test so the parent itself cannot be considered as P. With a log Kow of 4.4 and a measured BCF of 120,Kg/L the substance does not meet the screening criteria for B or vB and the substance has an acute toxicity >1 mg/L and so fails to meet the T screening criterion
