Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The PNEC derivation was as follows justified:
PNEC freshwater sediment:
K_(susp-water) = 708
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (708/1150)*4.4*1000
= 2.7 mg/kg wwt
= 12.5 mg/kg dw
PNEC marine water sediment:
K_(susp-water) = 708
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000
= (708/1150)* 0.44 * 1000
= 0.27 mg/kg wwt
= 1.27 mg/kg dw
PNEC soil:
K_(soil-water) = 142
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water)/ RHO_(soil))*PNEC_freshwater*1000
= (142/1700)*4.4*1000
= 0.367 mg/kg wwt
= 0.415 mg/kg dw

Classification,
Labelling, and Packaging Regulation (EC) No 1272/2008
The
available experimental test data are reliable and suitable for
classification purposes under Regulation (EC) No 1272/2008. Based on the
data above, the substance has not to be classified for short-term
(acute) aquatic toxicity, but for long-term (chronic) aquatic toxicity
the substance is Cat 2 (H411: Toxic to aquatic life with long
lasting effects)
according to Regulation (EC) No 1272/2008 (CLP), as amended for the
twelfth time in Regulation (EU) No 2019/521.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
