PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Persistence Assessment

The substance is neither readily nor inherently biodegradable in standard tests for biodegradability. However, the substance is subject to direct photolysis.

 

Bioaccumulation Assessment

Due to the very low log Kow of less than 0, the substance has no potential for bioaccumulation. The log Kow of the substance is much lower than the threshold value of the screening criterion for B (log Kow > 4.5). Furthermore, experimental tests on the substance on fish were performed and no evidence for bioaccumulation was indicated. In all experiments performed only trace concentrations (less than 0.05 mg/kg) of the tested substance were present in the fish at exposure levels up to of 1 mg/l. In most instances, no detectable substance levels were found.

Therefore B-criterion is not fulfilled.

 

Toxicity Assessment

The substance is non toxic to mammalian and aquatic organisms. The substance is classified neither for environmental toxicity nor as CMR or T, R 48 or Xn, R 48. It can be concluded that the substance has no toxic properties.
