Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Not specified
- GLP compliance:
- not specified
- Type:
- BCF
- Value:
- 0.6 dimensionless
- Basis:
- not specified
- Conclusions:
- The BCF for methylal, estimated from its octanol/water partition coefficient, 0.00, using a recommended regression equation (Lyman et al., 1990) is 0.6 (SRC). Therefore, methylal should not bioconcentrate in fish and aquatic organisms.
This information is peer reviewed in HSDB. - Executive summary:
The BCF for methylal, estimated from its octanol/water partition coefficient, 0.00, using a recommended regression equation (Lyman et al., 1990) is 0.6 (SRC). Therefore, methylal should not bioconcentrate in fish and aquatic organisms.
This information is peer reviewed in HSDB.
Reference
Description of key information
According to Annex IX in REACH regulation, for susbtance with a Kow value < 3, no study needs to be conducted. With a log Kow of 0.0, this condition is fulfilled for methylal. Methylal BCF was estimated at 0.6 with BCFBAF Programm (v3.00).
Methylal should not bioconcentrate in fish and aquatic organisms.
Key value for chemical safety assessment
- BCF (aquatic species):
- 0.6 dimensionless
Additional information
Methylal log BCF was estimated at 0.6 and 0.5 from Lyman et al. (1982) recommended regression equation (using log Kow of 0.00) and BCFBAF Programm (v3.00), respectively. Therefore, methylal should not bioconcentrate in fish and aquatic organisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
