Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Sediment toxicity

Description of key information
Toxicity to sediment organisms is not a standard information requirement in Annex IX. Therefore the equilibrium partitioning method has been used for the PNEC sediment derivation.
Key value for chemical safety assessment
Additional information
In the absence of measured data the PNECsedcan be provisionally calculated using the equilibrium partitioning method (EPM). According to the TGD this method uses the PNECaquaticand the sediment/water partitioning coefficient as inputs.
The PNECsed is then calculated using the equations detailed in the TGD |
|
PNECsed |
= Ksusp-water* PNECaquatic * 1000 * 1 / RHOsusp |
|
|
Where: |
|
PNECaquatic dissolved |
= 0.714 mg/L |
Ksusp-water |
= 0.908 m3/m3 |
RHOsusp |
= 1150 kg/m3(TGD, equ. 18) |
PNECsed-EPM |
= 0.564 mg/kg ww |
|
= 2.59 mg/kg dw |
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.
