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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 237-235-5 | CAS number: 13703-82-7
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- (Q)SAR
- Adequacy of study:
- weight of evidence
- Study period:
- 2018-01-08
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, and documentation / justification is limited
- Justification for type of information:
- please refer to 'Attached justification'
- Guideline:
- other: ECHA Guidance R.6
- Principles of method if other than guideline:
- - Software tool(s) used including version: EPIWIN v4.11
- Model(s) used: BCFBAF v3.01
- Model description: see field 'Attached justification'
- Justification of QSAR prediction: see field 'Attached justification' - Key result
- Type:
- BCF
- Value:
- 0.893 L/kg
- Conclusions:
- The Bioconcentration factor according to Arnot-Gobas method (upper trophic) is log BCF = -0.05 (BCF = 0.893 L/kg bw). However, the prediction does not fall into the applicability domain of this model, since the substance is inorganic.
- Executive summary:
The Bioconcentration factor (BCF) was predicted with BCFBAF v3.01 which is implemented in EPIWIN v4.11. The Bioconcentration factor according to Arnot-Gobas method (upper trophic) is log BCF = -0.05 (BCF = 0.893 L/kg bw). However, the prediction does not fall into the applicability domain of this model, since the substance is inorganic.
Reference
The prediction does not fall into the applicability domain of this model, since the substance is inorganic.
Description of key information
The Bioconcentration factor (BCF) was predicted with BCFBAF v3.01 which is implemented in EPIWIN v4.11. The Bioconcentration factor according to Arnot-Gobas method (upper trophic) is log BCF = -0.05 (BCF = 0.893 L/kg bw). However, the prediction does not fall into the applicability domain of this model, since the substance is inorganic.
This endpoint is not mandatory for the tonnage band 10 - 100 tpa (REACH Regulation Annex VIII). Data in a WoE approach is only provided in order to better estimate the bioaccumulation potential for the substance (please refer to PBT Assessment).
Key value for chemical safety assessment
- BCF (aquatic species):
- 0.893 L/kg ww
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.
