EC number: 201-898-9 | CAS number: 89-32-7
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
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The test material has a Log Pow of <= -2 at room temperature and is readily biodegradable (100% degradation after 28 days and satisfied the 10-Day window validation criterion). The calculated bioconcentration factor BCF calculated using Advanced Chemistry Development (ACD/Labs) Software V11.02 (© 1994-2017 ACD/Labs) was found to be 1.0 for the whole range of pH 1 to 10 at 25°C.

Description of key information
The study does not need to be conducted because the substance has a low potential for bioaccumulation based on the log Pow. The partition coefficient was found to be log Pow < -2 at room temperature. PMDA also attained 100% degradation after 28 days and satisfied the 10-Day window validation criterion. The test material can therefore be considered to be readily biodegradable.
The calculated bioconcentration factor BCF calculated using Advanced Chemistry Development (ACD/Labs) Software V11.02 (© 1994-2017 ACD/Labs) was found to be 1.0 for the whole range of pH 1 to 10 at 25°C.
Key value for chemical safety assessment
- BCF (aquatic species):
- 1 dimensionless
