PBT assessment: overall result

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

Persistence:


A study on "ready degradability" according to OECD 301F was conducted resulting in 0% degradation after 28 days based on CO2 evolution. It is then not expected to have a half live less than 40 days or 60 days and no further testing seems necessary. Thus, based on the screening data, the substance has to be considered to be persistent (P) or very persistent (vP).


Bioaccumulation:


The substance has a log Kow of  2.807 (Method OECD 123). Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumlative (vB).


Toxicity:


The NOEC of the long term toxicity to daphnids is 0.308 µg/L.
