An evaluation of the inherent properties of T002675 is performed against
the ANNEX XIII criteria. If insufficient data were available, the
screening criteria as laid down in ECHA Guidance on information
requirements and chemical safety assessment Chapter R.11: PBT Assessment
(2014) were applied.
The persistency assessment is based on the screening criteria in Annex
XIII of the REACH Regulation. The biodegradation potential of the test
substance has been assessed in a OECD 301F study (Seyfried, 2007). The
results reveal that the test substance does not degrade and the
substance is considered to be not readily biodegradable. It can
therefore be concluded that based on the criteria mentioned above the
substance is persistent in the environment. The substance is concluded
to be P/vP.
The bioaccumulation assessment is based on the screening criteria in
Annex XIII of the REACH Regulation. A measured Log Kow of 1.055 at pH 5
has been determined in an OECD 117 study (Paulus, 2007). Since the
measured log Kow of the parent compound is below the criterium of log
Kow < 4.5 no further assessment on bioaccumulation is needed. The test
substance is concluded to be not B/vB.
The toxicity assessment is based on the screening criteria in Annex XIII
of the REACH Regulation. The test substance is classified as toxic for
STOT RE category 1. The test substance hence, is considered to be Toxic.
In conclusion, taking into account that the substance is P/vP, not B/vB
and T, the substance should not be considered as a PBT/vPvB substance.
