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.

Description of key information
Key value for chemical safety assessment
Additional information
In Annex X, Section 9.5.1, Column 2 of Regulation (EC) No 1907/2006, it
is laid down that long-term toxicity testing on sediment organisms shall
be proposed by the registrant if the chemical safety assessment
indicates the need to investigate further the effects on sediment
organisms.
According to Annex I of this regulation, the chemical safety assessment
triggers further action when the substance or the preparation meets the
criteria for classification as hazardous according to Regulation EC
1272/2008 and its second adaptation 286/2011 or is assessed to be a PBT
or vPvB. The hazard assessment of the substance reveals neither a need
to classify the substance as hazardous to the environment, nor is it a
PBT or vPvB substance, nor are there any further indications that the
substance may be hazardous to the environment. The potential
transformation products of the substance were also assessed for their
PBT/vPvB status; none of the 24 relevant transformation products were
identified as PBT/vPvB substances (see IUCLID Ch. 5.2.1/5.2.2/5.2.3).
The substance has a low adsorption potential based on the estimated log
Koc, which is below 3 (see IUCLID Ch. 5.4.1). Hence, an adsorption to
activated sludge, suspended matter or sediment particles is unlikely.
Based on the low estimated BCF values, bioaccumulation in aquatic
organisms is not to be expected (see IUCLID Ch. 5.3.1).
As sediment is not an environmental compartment of concern, no test on
sediment toxicity is performed. The equilibrium partitioning method has
been used for assessing the hazard to sediment organisms.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
