Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Description of key information
Waiving of study:
In accordance with column 2 of REACH Annex IX, the Bioconcentration
Factor, BCF (required in section 9.3.2) does not need to be conducted as
calcium cyanamide is expected to have a low potential for
bioaccumulation.
- The substance is rapidly degraded within hours or a few days in
sediment and soil.
- In addition, the log Kow is expected ≤ 3 as the substance is highly
soluble in water. A very low logPow of -0.81 was calculated by EPIWIn
(v4.00) for the free acid. In addition based on its ionic structure it
is not likely to be dissolved very good in n-octanol.
- The calculated BCF for the free acid of calcium cyanamide of -0.047
also indicates no risk for bioaccumulation. The value for the Calcium
salt is expected to be even lower.
- Mammalian data does not indicate bioaccumulation.
Key value for chemical safety assessment
Additional information
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.
