Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2008
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- secondary literature
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 305 B (Bioaccumulation: Semi-static Fish Test)
- Version / remarks:
- 1996
- GLP compliance:
- not specified
- Details on sampling:
- Samples from both test solutions and test organisms were taken daily from the 26th day to the last day during the 28-day exposure test period. Samples were prepared by extracting the lipid component from the test fish.
- Test organisms (species):
- Danio rerio (previous name: Brachydanio rerio)
- Test type:
- static
- Water / sediment media type:
- natural water: freshwater
- Total exposure / uptake duration:
- 28 d
- Nominal and measured concentrations:
- Nominal concentration of 20 mg/L (mean measured concentration <0.023 mg/L)
- Reference substance (positive control):
- not specified
- Conc. / dose:
- <= 0.02 mg/L
- Type:
- BCF
- Value:
- < 100 dimensionless
- Remarks on result:
- other: limited details are available
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The BCF for Disperse Blue 077 was determined to be <100.
- Executive summary:
The bioconcentration of Disperse Blue 077 in Zebra fish (Brachydanio rerio) was determined in a 28-day semi-static test with a test medium renewal every two days. An exposure test at a nominal concentration of 20 mg/L (mean measured concentration <0.023 mg/L) was performed in accordance with the result of the fish acute toxicity test to check the bioconcentration potential of the test substance. Samples from both test solutions and test organisms were taken daily from the 26th day to the last day during the 28-day exposure test period. Samples were prepared by extracting the lipid component from the test fish. Based on the findings of the study, the BCF for Disperse Blue 077 was determined to be <100. Lack of detection in fish extracts (< 0.02 mg/L) suggests a limited solubility in lipids and/or limited potential to partition into fish tissue from aqueous systems - most likely both.

Description of key information
The BCF for Disperse Blue 077 was determined to be <100. The bioconcentration of Disperse Blue 077 in Zebra fish (Brachydanio rerio) was determined in a 28-day semi-static test with a test medium renewal every two days. An exposure test at a nominal concentration of 20 mg/L (mean measured concentration <0.023 mg/L) was performed. Based on the findings of the study, the BCF for Disperse Blue 077 was determined to be <100. Lack of detection in fish extracts (< 0.02 mg/L) suggests a limited solubility in lipids and/or limited potential to partition into fish tissue from aqueous systems - most likely both.
Key value for chemical safety assessment
- BCF (aquatic species):
- 100 dimensionless
