Administrative data

PBT assessment: overall result

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

An assessment of the PBT status of the substance has been made using all available data. The information available suggests that the substance does not meet the PBT screening criteria as outlined in Directive 2006/121/EC (Appendix A).

Persistence Assessment

 

In a OECD301F (manometric) study with 9% mineralisation at 28 days was observed. In three inherent tests, mineralisation was ranging from 20-36% after 28 days. It can be concluded from the available screening tests that the substance exhibits inherent (primary) biodegradability, and is therefore not expected to persist indefinitely in the environment. However, since the substance is not readily biodegradable and the biodegradation was less than 70% in the inherent tests, it has to be classified as P, according to the PBT screening criteria.

 

Bioaccumulation Assessment

 

In the absence of a measured BCF value, the log KOWcan be used as a screening criterion for bioaccumulative potential (i. e. >4.5). As the log KOWof the substance is below 4.5, the B/vB criterion is not met. Therefore the substance is identified as not B.

 

Toxicity Assessment

 

The acute effect information for all three trophic levels is much higher than the screening criterion of 0.1 mg/l. It can therefore be expected that the substance is not toxic towards aquatic organisms.

 

The overall conclusions, based on the present available data, of the preliminary PBT assessment are that the (screening) criteria for PBT/vPvB are not met and that further testing in the scope of the final PBT assessment is not considered to be required.
