PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
While BABS Acid does not meet the criteria for ready biodegradation in a standard study, a longer term study demonstrated over 98% biodegradation. Therefore, the substance undergoes extensive primary biodegradation and would likely be considered potentially P but not vP. Modeling results show a calculated BCF of Log 0.5 (BCF = 3.162), which when considering additionally that the substance has a low Log Kow (1.27) and is soluble in water ( 263.6 g/L), demonstrates that the substance is not expected to bioaccumulate and is not B. BABS Acid also does not meet the criteria for toxicity. Therefore, BABS Acid s not PBT and not vPvB.
